Procedures 1 Scope This document defines the quality requirements for suppliers of parts and materials that are used in MLA products. This document describes the expected actions, documentation, and communication to be used by MLA and MLA’s suppliers. The required actions defined in this document are intended to ensure that the supplier’s products meet the expectations of MLA and our customers. 2 General Requirements 2.1 Products quality It is the expectation of MLA that each supplier will provide parts that meet all the functional, physical, and other requirements listed on the drawing and associated specifications. The use of subcontractors; independently selected, MLA-designated, or ML-approved, does not relieve the supplier of the responsibility to ensure the quality of subcontracted parts, materials, and services. 2.2 Quality management System 2.2.1 Quality Planning The supplier shall implement and maintain a quality system that has been well conceived through careful planning such as the current ISO 9001 or equivalent standard. The supplier’s quality system shall be documented in a quality manual. The quality manual shall detail the procedures that the supplier uses to ensure product quality including, but not limited to, process controls, training, and implementation of effective corrective actions, and have the approval and direction of executive management of the supplier's facility. 2.2.2 Control of Process Suppliers shall control product realization processes according to their quality system as approved by MLA. If the system should deviate including, but not limited to, relocation of equipment, facility, etc., it is the supplier's responsibility to take the necessary action to re-establish control. The supplier shall apply procedures and effective controls sufficient to maintain required specifications, reduce variation, document inspection and test results, and maintain identity of materials throughout the process. Written processing and inspection/test instructions should be readily available, understood, and followed by appropriate personnel. 2.2.3 Product Monitoring and Measurement MLA nonconforming material shall be identifiable as to process status and shall be reviewed for correction or rejection. The supplier shall ensure that nonconforming material is not shipped to MLA without written MLA deviation approval. If written deviation approval from MLA is granted, a copy of the deviation record must be submitted with the product shipment in accordance with the Product Inspection Report Submittal Requirements listed below. 2.2.4 Control of Measuring Devices The supplier shall establish and maintain documented procedures to control, calibrate, and maintain inspection, measuring, and test devices used to ensure conformance of the product to the specified requirements. 3|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Calibration and test sources must be accredited to ISO/IEC 17025 or equivalent. Inspection, measuring, and test equipment shall be used in a manner that ensures that the measurement uncertainty is known and is consistent with the required measurement capability. 2.2.5 Lot Control Suppliers shall have lot identification control procedures in effect when materials and/or processes require lot segregation for effective control and traceability. 3 Supplier Approval Process 3.1 General All new suppliers must be approved within the ML group of companies. This process will be initiated upon identification of the supplier as a potential candidate for MLA. The approval process will include completion of a self-assessment using the form contained in CAQ023. In cases where the supplier will provide class I or II parts as defined in MSJ1-2002, this will also include an on-site assessment by an ML company quality representative. The self-assessment and on-site assessment, if required, shall result in a minimum score as shown in table 1 below. Part Class Minimum Score I 90 II 80 III 60 Table 1 – Quality System Assessment Score Requirements Quality system approval can be revoked at any time at the discretion of MLA. 3.1.1 Conditional Approval MLA, at its discretion, may give temporary conditional approval. To gain full approval, the supplier will be required to complete improvements to their quality system as directed by the Auditor. These improvements must be made within the time frame established by the Supplier Quality Engineer (SQE), or the conditional approval will be revoked. 3.1.2 Sub-tier Suppliers Sub suppliers may be audited based on the complexity or criticality of part(s). Below is a flow chart showing how to decide the necessity of audit for sub suppliers. 4|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 3.2 Special Process Audit Special processes (e.g., forging, casting, and heat treating) audit may be required and will be determined by the part requirement and criticality on the drawing. The assessment forms (XAR201-XAR216) will be provided as needed by MLA Supplier Quality Engineer (SQE). 4 Production Part Approval Process (PPAP) 4.1 General PPAP elements address the planning and production activities for purchased parts to reduce the potential for receipt of defective components at MLA. The supplier will be required to submit/attach PPAP documentation as per the drawing requirements to Commodity Manager and/or Supplier Quality Engineer (SQE)upon their request. PPAPs will be required in each case where a supplier is making a new production part number for MLA. Unless otherwise specified, on new programs, PPAPs will be required in the pre-production phase. The documentation and parts submitted shall be representative of the intended production process, including tooling. If parts are not representative, notify the Commodity Manager. 5|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 4.2 Element Requirements Supplier Quality Engineer (SQE) will determine PPAP level based on part drawing and/or MSJ12002E. Part class level can be found on the drawing bottom right corner (See below image). o If this section does not have circle on class 1 or 2, it is deemed as class 3 part. o 4.2.1 Level 2 PPAP (Class 1 and 2 Parts) Bubble Print and Inspection Report ✓ Labeled or numbered in an orderly fashion and correspond to the Inspection Report. ✓ General form used by both MLA and the supplier for documenting the evaluation of dimensional inspection. Quality Control Plan ✓ A planning tool used to summarize and document product and process control characteristics, the capability of process/measuring systems and the plan to control the process (Appendix A). In terms of control plan, suppliers may use their standard format or may contact the MLA Supplier Quality Engineer (SQE) for an example form (Appendix A). Performance Test Report 6|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures ✓ General form used by both MLA and the supplier for documenting the evaluation of material, and performance specifications mentioned on MLA drawing. ✓ Related standards for each part are described in the top right column or note in blank area of drawings (refer following pictures). In case supplier needs any information about part standards, supplier shall reach out to commodity manager. 7|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Material Certificate ✓ The supplier shall perform tests for part(s) and product material(s) when chemical, physical, or metallurgical requirements are specified on MLA drawing. ✓ Materials requiring records, certifications and /or test results include but are not limited to: Structural steels including plate, sheet, tubing, bars, rounds, and shapes. Casting, forging and Welded products. Weld Penetration Test ✓ A welding penetration test will be required for all welded parts. All parts requiring welding shall follow P-M40UCA-01 welding standard and testing requirements. FMEA Analysis or Process Flow Diagram. ✓ The process FMEA is a document that describes the potential failure modes, potential causes of those failures, and calculated risk associated with each potential cause in processes. Suppliers may use their standard FMEA format or may contact the MLA Supplier Quality Engineer (SQE) for an example form (Appendix B). Process Capability Study plan & Results. ✓ CpK – The capability index for a stable process. The estimate of the standard deviation is based on variation within the subgroup. ✓ Capability study will be required for all tight tolerance machined class 1 parts. MLA Supplier Quality Engineer (SQE) will provide dimensions or specifications that are required capability study to suppliers. For process capability study submissions, products shall be manufactured at the production site using the tooling, gauging, process, materials, and operators from the production environment. This production run shall be a minimum of 30 consecutive parts, unless otherwise specified by the supplier quality representative. MLA SQE may request suppliers to improve measuring methods or frequency in their regular production process if there are dimensions or specification that are below Cpk 1.33. Suppliers may use their standard format for capability study, but MLA SQE will send a calculation sheet if requested. (Appendix C). Results Interpretation Index Value > 1.33 The process currently meets MLA requirements. The process is currently acceptable but may require 1.00 ≤ Index Value ≤ 1.33 some improvement. The process does not currently meet the acceptance Index Value < 1.00 criteria. 4.2.2 Level 4 PPAP (Class 3 Parts) Bubble Print and Inspection Report 8|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures ✓ Labeled or numbered in an orderly fashion and correspond to the Inspection Report. ✓ General form used by both MLA and the supplier for documenting the evaluation of dimensional data. Quality Control Plan ✓ A planning tool used to summarize and document product and process control characteristics, the capability of process/measuring systems and the plan to control the process. In terms of control plan, suppliers may use their standard format or may contact the MLA Supplier Quality Engineer (SQE) for an example form (Appendix A). Performance Test Report ✓ General form used by both MLA and the supplier for documenting the evaluation of material and performance specifications mentioned on MLA drawing. ✓ Related standards for each part are described in the top right column or note in blank area of drawings (refer following pictures). In case supplier needs any information about part standards, supplier shall reach out to commodity manager. 9|Page Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Material Certificate ✓ The supplier shall perform tests for part(s) and product material(s) when chemical, physical, or metallurgical requirements are specified on MLA drawing. ✓ Materials requiring records, certifications and /or test results include but are not limited to: Structural steels including plate, sheet, tubing, bars, rounds, and shapes. Casting, forging and Welded products. Weld Penetration Test: ✓ A welding penetration test will be required for all welded parts. All parts requiring welding shall follow P-M40UCA-01 welding standard and testing requirements. 4.3 Tooling Consideration All tooling to be paid by MLA must be ordered on a purchase order and unless otherwise agreed upon, final tooling invoices shall be paid only after MLA approves the initial samples produced with production tooling. An on-site inspection of the tooling utilized by the supplier to produce the MLA parts may be waived based upon the type of tools and volume requirements. However, MLA representatives upon demand may inspect all tooling owned by MLA and held at the supplier's location. The supplier shall identify all MLA tooling that is held at the supplier's location with an appropriate identification control system for easy identification. 10 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Additional Drawing Examples 11 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Additional Drawing Examples 12 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 4.4 PPAP Review After sample parts and documentation have been submitted to MLA by supplier, Supplier Quality Engineer (SQE) will review documentation. PPAP approval will be indicated on the part submission warrant (PSW). The PSW is generated automatically in our system; therefore, the supplier is not required to submit their warrant to MLA. If a PPAP component is deemed to be deficient by the MLA SQE, the supplier will be notified of the deficiency and will be requested to resubmit that PPAP component. 5 Supplier Quality Score 5.1 General MLA assigns a score to each supplier monthly to grade their quality performance for the month. The quality score is a component of the overall score used to evaluate supplier performance by our sourcing group. Scoring is based on PPM which is determined by dividing the quantity of pieces rejected by total pieces received in each month times one million. Suppliers with low scores are reviewed on a regular basis to determine if corrective action is needed. 5.2 Scoring There are twenty-five (25) points available for the quality section of the supplier score. Scores are established using receiving inspection results and line rejects. Full points are awarded for achieving a PPM equal to or less than 400 PPM. No points will be awarded for a supplier with a PPM of 5000 or greater. The following table lists PPM scores and its classification rating. PPM Scoring Range Classification 400 or less 25 Excellent A 401-585 24 Acceptable B 586-770 23 Needs Improvement C 2145 or more 16 or less Unacceptable D Table – Supplier Scores 6 Rejected Material Report (RMR) 6.1 General If a nonconformance is found, MLA communicates the problem using an RMR. It is MLA’s policy to return nonconforming parts or material to the supplier for replacement. There may be situations where MLA chooses to not enforce this policy and, in these instances, other actions may be taken based upon internal evaluations and discussions with the supplier. 6.2 RMR Notification and Response Process Upon generation of an RMR, the supplier will be notified by e-mail which may contain a hyperlink to the RMR. The supplier shall provide a returned goods authorization (RGA) and shipping instructions in the area provided on the 13 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures RMR. Supplier shall make first reply to RMR within 3 days in case local supplier and 5 days in case international supplier. Upon receipt of the RGA, MLA will return the defective material to supplier at the supplier’s expense. 6.3 Alternative RMR Response Processes In those cases where the material will not be returned to the supplier, the supplier shall initiate an alternative process to satisfy their obligations. Alternatives to our standard policy include deviation, rework, or sort. At the supplier’s request, parts may also be scrapped at MLA at supplier’s expense. 6.3.1 Deviation The commodity manager, in coordination with the supplier, may request that the parts be used as-is by using the deviation process. The deviation request will be filled in by the commodity manager and will be routed to the appropriate personnel at MLA. If approved, the parts may be used. 6.3.2 Rework Defective parts may be reworked by the supplier at MLA or by a third party. The supplier is expected to arrange all rework activities, including transportation to and from the rework location. MLA may be willing to rework defective parts at the supplier’s expense; however, we do not have the staff to accommodate rework. The supplier will be charged our fully burdened overtime rate for rework performed by MLA personnel. The supplier will be charged our fully burdened overtime rate of $100 per hour for reworking performed by MLA personnel. 6.3.3 Sort at supplier expense Defective parts may be sorted by the supplier at MLA or by a third party. The supplier is expected to arrange all sorting activities, including transportation to and from the sorting location. MLA may be willing to sort defective parts at the supplier’s expense; however, we do not have the staff to accommodate this additional work. The supplier will be charged our fully burdened overtime rate of $100 per hour for sorting performed by MLA personnel. Nonconforming parts will be managed per the requirements stated in section 6 as appropriate. 14 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 6.4 Appeal The supplier may appeal against a rejection by MLA by making a request with the quality department or commodity manager at MLA. The facts supporting the appeal will be considered by the MLA and the supplier will be notified of our decision. If the appeal is accepted, the RMR will be modified or voided as appropriate. 6.5 Failure to Respond If the supplier fails to respond to an RMR, MLA will send a reminder of the need to respond. If the supplier has not responded in 30 days, the commodity manager will be notified to help resolve the problem. If a response is not received at 45 days, MLA reserves the right to return the parts at the supplier’s expense or take other actions as necessary to support MLA’s needs. Failure to respond will be considered as implicit acceptance of MLA decisions and associated charges. It is the supplier’s responsibility to notify MLA Quality and Purchasing of any personnel changes. 7 Supplier Corrective Action Request 7.1 General The notification of supplier corrective action request is a process used by MLA to gain confidence in the supplier’s ability to provide consistent quality or perform at a higher level than has been demonstrated. Reasons for supplier corrective action request generation include grievous defects, recurring problems, serious production impact, or other reasons at the discretion of the Supplier Quality Engineer (SQE). The supplier should consider the supplier corrective action request to be an indication of MLA’s perception that a serious system deficiency exists and should treat the subject with urgency and thoroughness. 7.2 Containment It is our expectation that containment will be initiated immediately upon receipt of notification that a problem has been detected at MLA. Containment must be sufficient to prevent future shipment of additional defective products to MLA and require documentation. MLA will request 3D/6D/8D investigation depending on the impact of rejection. 7.3 Root Cause The supplier is responsible for investigation into the root cause of the problem and may be assisted by an MLA if such assistance is needed. Adequate root cause investigation is necessary to ensure that corrective action can be implemented in a manner that prevents future problems. The results of the root cause investigation shall be documented. MLA will request 3D/6D/8D investigation depending on the impact of rejection. 7.4 Corrective Action Corrective action must address the root cause and ensure that the defect will not reoccur. Corrective action will be reviewed for adequacy and approved after the effectiveness is verified by the Supplier Quality Engineer (SQE). 15 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 8 Reliability 8.1 General Our suppliers are a critical partner in providing forklifts to our customers that perform in the expected manner for their design life. To ensure adequate product life, MLA will define testing and analyses for selected components to validate acceptable performance in expected operating conditions. These tests and analyses may be defined at the component level or higher as deemed necessary by MLA. The supplier may perform additional tests and analyses at their discretion that supplement defined requirements. It is expected that the supplier will actively and independently review reliability performance and pursue solutions to reliability problems that may arise throughout the component life cycle. 8.2 Warranty Reduction Activities Warranty claims reflect the supplier’s contribution to the reliability of our forklifts. We expect the supplier to actively pursue reduction of warranty claims through process improvements and design changes. The MLA Supplier Quality Engineer (SQE) will assist the supplier in investigations and understanding of product application issues that may contribute to warranty as needed. 9 Process Change Requirements Any change that may affect quality or reliability of purchased components shall be reported to the MLA Supplier Quality Engineer (SQE) and Purchasing groups at least 90 days prior to implementation of the change via 3M Process Change Notice form found in Appendix D. Approval must be obtained from MLA prior to shipping parts produced under these changed conditions. The following table lists common changes and typical requirements associated with those changes. MLA Change Description Typical Requirement Facility Move Quality System Assessment, New PPAP Sub Supplier Change Quality System Assessment, New PPAP as required Production Line Move New PPAP Material Change New PPAP Manufacturing Process Change New PPAP Manufacturing Equipment Change New PPAP Table 3 – Typical Change Requirements Requirements associated with changes not listed in the table above will be defined by the MLA Supplier Quality Engineer (SQE). 16 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 10 Supplier Request for Design Change The supplier is encouraged to request changes to MLA designed components to improve quality, reliability, cost, or function. All design change requests should be initiated and routed through the appropriate Commodity Manager. The Commodity Manager will coordinate all activities associated with the proposed change with appropriate personnel at MLA and supplier. 11 Deviation Request MLA drawings and standards define the part or assembly requirements. A verbal agreement between the supplier and anyone at MLA does not relieve the supplier from the responsibility of meeting the requirements listed on the drawings and specified standards. An approved MLA deviation request is the only acceptable document relieving the supplier of their responsibility to meet all drawing and documented specifications. Prior to shipment of parts or assemblies that do not meet MLA requirements, the supplier shall submit a deviation request to the MLA commodity manager and buyer/planner in order to receive confirmation of approval. 12 Drawing Control All Suppliers shall maintain latest revision drawings of MLA parts, including all the standards. These drawings and engineering standards shall be kept at the supplier’s location as controlled documents. Related standards for each part are described in the top right column or note in blank area of drawings. Supplier also shall keep those standards. In case supplier needs any information about part standards as shown in below ML drawing example, supplier shall reach out to. 17 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures 13 Confirmation of quality assurance system and quality control 13.1 Quality records MLA may request the submission of documents or records related with quality of products such as inspection record etc. to confirm the quality assurance system and quality control of the supplier's products. 13.2 Quality Audit MLA may request to enter the supplier's factory or office, with the supplier's consent, to confirm the supplier's quality assurance system and quality control for the products for MLA. 14 Quality Standards 14.1 Welding The standard “P-M40UCA-01 apply to all welded components unless otherwise specified in print (Please refer to attached file). 14.2 Cosmetics Cosmetics of products shall follow standard “P-M10UCA-02” (Please refer to attached file). 14.3 Special Standard If there are any quality requirements that cannot be clearly expressed numerically in the specifications, MLA may establish quality standards which may have visual aids etc. with supplier's agreement. 18 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Appendix A – Example format of control plan 19 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Appendix B –Example format of process FMEA 20 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Appendix C - Example format of capability study 21 | P a g e Document Title Governing Department Approval Manager Revision Date Revision Number SQM Supplier Quality RJ Patel 4/29/2024 0 SQM - Supplier Quality Requirements & Procedures Appendix D – 3M Process Change Notice 3 M Process C hange N otice V en d or en try f ield Su p p lier n ame: A p p lication d ate: 1.

Objective This Standard applies to all structural welds used in the manufacture of forklift equipment and should be used to establish standard acceptance criteria for the visual and dimensional inspection of welds. The purpose of this standard is to evaluate and maintain weld quality levels consistent with industry practice and maintain confidence that the product welds will perform as intended. Specific practices and weld parameters used for production welding are to be based on those used to qualify the process. This is accomplished through documented Welder Performance Qualifications (PQR) and a Welding Procedure Specification (WPS) program. Continuous weld process quality validation is accomplished through the implementation of OP 7.5.2.QE. Weld evaluation should be made prior to paint and/or assembly to ensure complete visual access and provide for a more professional rework, where required. 2.

DEFINITIONS: Consistent Finish: A surface condition that is harmonious over the entire area. If the material is lightly textured, it must be lightly textured over the full surface. Localized surface variations will be cause for rejection. Customer Interface Surface: Typically a high gloss, smooth surface associated with the Class 1 specification. Class 1 surfaces are those that have high visibility to the fork truck operator. Discontinuity: Any local variation in material continuity, including change in geometry, holes, cavities, cracks, structure, composition, or properties. Injurious Defect: When any discontinuity, single or multiple, is of such size, shape, type, and location that it creates an elevated chance of material failure in service. Localized Imperfection: A surface feature that causes the visual perception of a discontinuity and is evident as an inconsistent surface finish. A localized imperfection can be light grinding marks resulting in a uniform finish but is unacceptable due to the inconsistency of the surface. Mill Finish: The finish produced in hot rolling that does not conform to any definite contour. Mill finish products may contain some discontinuities, the more common of which are checked surfaces and edges, thin edges (feather) or damaged surfaces and edges due to handling or processing. Workmanlike Finish: A finish that is in compliance with the requirements of this standard as specified on the purchase order. (2) Scratches: A linear defect over 5mm that can be repaired by polishing with a fine particle compound. Scratches are acceptable for all Class surfaces, provided they cannot be felt with the fingertip. Gouges: Hollowed out areas, either linear or rounded. Gouges are prohibited on Class 1 & 2 surfaces and acceptable on 3 & 4 surfaces if the depth and length of the gouge do not exceed the requirements of the applicable standard. Pits: The wasting of base material as a result of corrosion. Corrosion pitting is unacceptable on Class 1 & 2 surfaces. Isolated pitting less that 0.5mm in diameter is tolerable on Class 3 & 4 surfaces provided there is no loose rust or scale involved and the depth does not exceed the limits of the applicable standard. Grinder or Jitterbug swirl marks: Scratch like indications left as a result of power sanding. Swirl marks shall be evaluated using the scratch criteria. Rolled in scale impressions: Light indications pressed into the material as a result of a forming operation. Acceptable if the indications cannot be felt with the fingertip. Friction Digs: Light indications pressed into the material as a result of a forming operation. Acceptable if the indications cannot be felt with the fingertip. Roller Marks: Light indications pressed into the material as a result of a forming operation. Acceptable if the indications cannot be felt with the fingertip. Die Marks: Light indications pressed into the material as a result of a forming operation. Acceptable if the indications cannot be felt with the fingertip. Weld bead, defect etc: Refer to UCA’s Engineering Standard P-M40UCA-01. (3) 3. GENERAL REQUIREMENTS: The material furnished under this standard shall conform to the requirements of the current edition of the applicable ASTM standard. Additional supplementary requirements necessary to meet the quality requirements specified in the standard shall also be met. The material shall be free of injurious defects and shall have a workmanlike finish. Any discontinuity open to the surface shall be considered potentially injurious and shall be characterized by the wet magnetic particle (MT) inspection method to determine size, orientation and frequency. All suspected potentially injurious indications shall be referred to UCA for a determination based on component use and discontinuity location. It is the supplier’s responsibility to exercise their right of rejection (ASTM A 6/A 6M, paragraph 17.2) of all material with questionable discontinuities, ensuring compliance to this standard and the requirements of the intended application. Any indication that causes UCA or the end user to question the integrity of the part is unacceptable. There shall be no unauthorized weld repair on the material provided to UCA. 4. UNACCEPTABLE MATERIAL CONDITIONS: Seams: Longitudinal discontinuity on the surface of the material and caused by entrapped gas. Seams are elongated during the rolling process and, when viewed in the cross section, are perpendicular to the surface. Laps: Discontinuities that occur during the hot rolling of both semi-finished and finished material. Laps are the folding over of material and caused from gouging during the rolling process or misalignment of the rolls. Lamination: A subsurface, nonmetallic discontinuity flattened by the rolling process and aligned parallel to the rolling direction. Laminar tear: A subsurface, step-like crack in the base metal propagating from a lamination and with the basic orientation parallel to the rolled direction. Cracks / Linear indication: Any linear discontinuity with length 3 times greater than width and can be either surface or subsurface. 5. COSMETIC SURFACE CLASSES: Surface classification is determined by product use and customer visibility and can be referenced in the attached supplement. There are four designations of surface classes used to distinguish between the highly visible areas to the least visible locations. Material selection shall be based on the cosmetic as well as the functional requirements of this standard. Merchant Quality steel (e.g. A36M) is unacceptable for use in any UCA applications, unless specifically called out on the drawing. (4) 6. COSMETIC SURFACE CLASS DESIGNATIONS: Class 1: A consistent finish with no rust or scale. Class 1 surfaces are typically those provided by a cold rolled or cold reduced process. Visually, the class 1 surface is comparable to a 240 grit finish, at least a 16 Ra rating or confirmed by visual comparison with a micro finish comparator surface finish block. *Class 1 surfaces are considered a customer interface surface that requires a consistent finish. Trim panels and overhead guard pillars are examples of class 1 surfaces. Class 2: A consistent finish with no rust or loose scale. Class 2 surfaces are typically those provided by shot blasting, pickled and oiled product or a quality hot rolled mill finish. Visually, the class 2 surface is comparable to a 60 grit finish, at least a 125 Ra rating or confirmed by visual comparison with a micro finish comparator surface finish block. *Class 2 surfaces are highly visible locations without the requirement of the high gloss appearance due to the functional requirements of the parts. Masts and counterweights are examples of surfaces considered class 2. Classes 3 & 4: A typical mill finish with no rust or scale and not requiring a consistent finish. *Classes 3 & 4 finishes are typical of those areas least visible to the operator. (5) 7.
