In order to operate pressure equipment at an acceptable level of risk, the extent and frequency of inspection, the quality of process control and monitoring and the potential consequence of failure shall be taken into account. NOTE: Guidance on risk management is given in Appendix B. 1.6 SAFETY Appendix C sets down principles and procedures to be followed to ensure the safety of personnel during the inspection of pressure equipment. 1.7 SPECIAL CONDITIONS AND VARIATIONS It is not possible to write requirements to cover all cases of in-service inspection of pressure equipment. In special cases there may be a need to depart from the requirements in this Standard. Where departure from this Standard is necessary, the departure shall— (a) be justified and fully documented by a competent person; and (b) give a level of safety and quality that is no less than that specified in this Standard. Any departure from this Standard is the subject of agreement between the parties concerned. 1.8 REFERENCED STANDARDS Where this Standard makes reference to other Standards, these referenced Standards are not intended to be limiting or exclusive and alternative standards may be substituted for the referenced standards, where these give an equivalent level of safety and equipment quality. A list of pressure equipment Standards used in Australia and New Zealand and procedures for their use are included in AS/NZS 1200. COPYRIGHT Purchased By : Ms Renu Renu.

AS/NZS 3788:2006 10 SECTION 2 INSPECTION REQUIREMENTS 2.1 OBJECTIVES OF INSPECTION The objectives of in-service inspection are to— (a) promote the safety and health of persons in the workplace and of the public; (b) comply with occupational health and safety legislation; (c) limit the potential damage to property; and (d) protect the environment, through the control, reduction or elimination of risk associated with the pressure equipment. These objectives are achieved by— (i) verifying that fabrication and operation comply with design conditions; (ii) verifying that pressure equipment is safe and fit for service under the specified operating conditions until the next planned inspection; (iii) verifying that maintenance, repairs, and alterations are carried out in a manner which maintains the integrity of the pressure equipment; (iv) indicating repairs, replacements or alterations which may be needed, and assessing remaining safe life of the pressure equipment. Additional inspections may be carried out for a number of reasons, including, but not limited to— (A) assessment of the early performance of new design, material, fabrication, and testing; and (B) investigation and assistance in determining the causes of failure, hazards, reduced performance, or abnormal conditions which may lead to failure, and to determine what consequent temporary or long-term action is required to ensure continued safe operation or life commensurate with commercial requirements. 2.2 ASSET INTEGRITY LIFE CYCLE Fitness for service during the overall life cycle of pressure equipment is determined by activities at the stages listed as follows: (a) Concept—initially when many main decisions which affect ultimate safety (and inspection) are made. (b) Design—usually design review and verification. (c) Material—usually examination, marking and certificate correlation. (d) Fabrication. (e) Installation. (f) Commissioning—including identification and registration. (g) Operation—on line. (h) Periodic in-service inspection. (i) Maintenance. COPYRIGHT
