Study Notes
Philippine Agricultural Engineering Standard (PAES 316:2002)
- This standard specifies metal bars, pipes, and tubes for agricultural machinery and structures.
- It follows PNS 01-4:1998 (ISO/IEC Directives Part 3:1997) for structure and drafting of international standards.
Foreword
- The standard was initiated by AMTEC to enhance AFMA implementation through improved agricultural engineering standards, funded by BAR of the Department of Agriculture (DA).
- "Shall" indicates mandatory requirements for compliance.
- "Should" indicates recommendations, not strict requirements.
- Several references were consulted, including the James F. Lincoln Arc Welding Foundation, and various ISO standards (dimensions of hot-rolled steel sections, hot-rolled steel bars, etc.).
Scope
- This standard defines specifications and technical information for metal bars, pipes, and tubes used in agricultural machinery and structures.
References
- The standard references several international standards (JIS, PNS) related to steel, general structures, corrosion resistance, and pipes for various applications.
Application
- Metal bars, pipes, and tubes are used for components, structural framing, and mechanical elements for agricultural machines and structures in agriculture.
Definitions
- Bar: A long, evenly shaped piece of solid metal.
- Deformed bar: Steel bars with protrusions (lugs).
- Nominal diameter of deformed bar: Equivalent diameter of a round bar with the same mass per meter.
- Pipe: Long hollow cylinders of specified thickness.
- Tube: Long, hollow products of various shapes and dimensions.
Bars - Classification
- Bars are classified by cross-section (Figure 1).
- Round (smooth or deformed).
- Square.
- Flat.
- Angled (equal/unequal legs).
- Channel sections.
- I-beams.
- Detailed dimensions are provided in Tables 1-8.
Dimensions
- Tables 1-8 outline dimensions and properties (mass per unit length, moment of inertia, section modulus) for various bar cross-sections (round, square, flat, equal-leg/unequal-leg angled, channel, I-beams).
- Specific tables detail dimensions for different types of bars and variations in dimensions.
Nomenclature
- The standard details how to denote dimensions of bars.
Materials (For Hot-Rolled Steel Bars)
- Material specifications are referenced to JIS standard for hot rolled steel bars.
- Mechanical properties (yield and tensile strength) are given in Table 9 for different grades.
Designation and Markings
- Bars and pipes have unique marking systems with manufacturer information, specification details, and dimensions.
- Detailed markings and codes are illustrated in Figures 2 and 3.
Pipes – Classification and Dimensions
- Pipes are categorized into light and heavy gauges.
- Dimensions are specified in Table 10.
Tubes – Classification, Dimensions and Materials
- Tubes are categorized by shape. (e.g. circular, square, rectangular).
- Dimensions for different tube types are given in Tables 12-14.
- Materials for tubes, particularly carbon steel, follow specific JIS standards (Table 11).
Nomograms (Figures 4 and 5)
- Nomograms (Figures 4 and 5) provide methods to determine appropriate dimensions based on loading, length of the beam, and allowable stress.
