1.1This specification2 covers a group of requirements which, with the exceptions of 6.3 and Sections 7, 8, 19, 20, 21, 22, 23, 24, and 25, are mandatory requirements to the following ASTM tubular product specifications:3
| Title of Specification | ASTM DesignationA |
| Electric-Resistance-Welded Carbon Steel and Carbon-Manganese Steel Boiler Tubes | A178/A178M |
| Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes | A179/A179M |
| Seamless Carbon Steel Boiler Tubes for High-Pressure Service | A192/A192M |
| Seamless Medium-Carbon Steel Boiler and Superheater Tubes | A210/A210M |
| Electric-Resistance-Welded Carbon Steel Heat-Exchanger and Condenser Tubes | A214/A214M |
| Seamless and Electric-Welded Low-Alloy Steel Tubes | A423/A423M |
| Specification for Seamless and Welded Carbon Steel Heat-Exchanger Tubes with Integral Fins | A498/A498M |
| Seamless Cold-Drawn Carbon Steel Feedwater Heater Tubes | A556/A556M |
| Seamless, Cold-Drawn Carbon Steel Tubing for Hydraulic System Service | A822/A822M |
1.2One or more of Sections 6.3, 7, 8, 19, 20, 21, 22, 22.1, 24, and 25 apply when the product specification or purchase order has a requirement for the test or analysis described by these sections.
1.3In 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.
1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation (SI) of the product specification is specified in the order.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
