This specification covers general requirements for ferritic alloy steel, austenitic alloy steel, and stainless steel tubes. The steel shall made by any process. The material shall conform to the tensile property requirements prescribed in the individual product specification. Yield strength tests and elongation tests shall be made to conform to the requirements. Flattening test, reverse flattening test, reverse bend test, flaring test, flange test, hardness test, ultrasonic test, eddy current test, flux leakage test, and hydrostatic test shall be made to conform to the requirements specified.

1.1 This specification covers a group of requirements that, unless otherwise specified in an individual specification, shall apply to the ASTM product specifications noted below.

1.2 In the case of conflict between a requirement of a product specification and a requirement of this general requirements specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this general requirements specification and a more stringent requirement of the purchase order, the purchase order shall prevail.

1.3 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.
