ASTM A530/A530M-12
1.1 This specification covers a group of requirements which, with the exceptions of Section 6.3, Section 14, Section 21, and Section 22, are mandatory requirements to the ASTM pipe product specifications noted below unless the product specification specifies different requirements, in which case the requirement of the product specification shall prevail.
1.2 Sections 6.3 or 21 are mandatory if the product specification has a requirement for product analysis or flattening tests.
1.3 Section 22 is mandatory if the product specification has a hydrostatic test requirement without defining the test parameters.
1.4 Section 14 is for information only.
1.5 In case of conflict between a requirement of the product specification and a requirement of this general requirement specification, only the requirement of the product specification need be satisfied.
| Title of Specification | ASTM DesignationA |
| Seamless Carbon Steel Pipe for High-Temperature Service | A106/A106M |
| Metal-Arc-Welded Steel Pipe for Use With High- Pressure Transmission Systems | A381 |
| Seamless Carbon Steel Pipe for Atmospheric and Lower Temperatures | A524 |
| Centrifugally Cast Carbon Steel Pipe for High- Temperature Service | A660 |
| Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures | A671/A671M |
| Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures | A672/A672M |
| Carbon and Alloy Steel Pipe, Electric-Fusion-Welded for High-Pressure Service at High Temperatures | A691/A691M |
A These designations refer to the latest issue of the respective specifications.
1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation (SI) of the product specification is specified in the order.
Note 1—The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
