ASTM A703/A703M-12a

1.1 This specification covers a group of common requirements that, unless otherwise specified in an individual specification, shall apply to steel castings for pressure containing parts under each of the following ASTM specifications:

Title of Specification	ASTM Designation
Steel Castings, Carbon, Suitable for Fusion Welding for High-Temperature Service	A216/A216M
Steel Castings, Martensitic Stainless and Alloy for Pressure-Containing Parts, Suitable for High- Temperature Service	A217/A217M
Castings, Austenitic, Austenitic-Ferritic (Duplex) Pressure-Containing Parts	A351/A351M
Steel Castings, Ferritic and Martensitic, for Pressure Containing Parts, Suitable for Low-Temperature Service	A352/A352M
Steel Castings, Alloy, Specially Heat-Treated, for Pressure-Containing Parts, Suitable for High- Temperature Service	A389/A389M
Steel Castings Suitable for Pressure Service	A487/A487M
Castings, Iron-Nickel-Chromium and Nickel Alloys, Specially Controlled for Pressure Retaining Parts for Corrosive Service Castings, Austenitic-Ferritic (Duplex) Stainless Steel, for Pressure-Containing Parts	A990 A995/A995M

1.2 This specification also covers a group of supplementary requirements which may be applied to the above specifications as indicated therein. These are provided for use when addi- tional testing or inspection is desired and apply only when specified individually by the purchaser in the order.

1.3 In case of conflict between the requirements of the individual specification and this general specification, the former shall prevail.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.
