1.1 This specification 2 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 Seamless Cold-Drawn Carbon Steel Feedwater Heater Tubes A556/A556M Seamless, Cold-Drawn Carbon Steel Tubing for Hydraulic System Service A822/A822M (A) These designations refer to the latest issue of the respective specifications. 1.2 One 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. 1.3 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. 1.4 The 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.
