1.1 This specification covers a group of common requirements that shall apply to steel flanges, forged fittings, valves, and parts for piping applications under any of the following individual product specifications: | Title of Specification | ASTM Designation | | | Forgings, Carbon Steel, for Piping Components | A105/A105M | | Forgings, Carbon Steel, for General-Purpose Piping | A181/A181M | | Forged or Rolled Alloy-Steel Pipe Flanges, Forged | A182/A182M | | Fittings, and Valves and Parts for High Temperature Service | | Forgings, Carbon and Low Alloy Steel, Requiring Notch | A350/A350M | | Toughness Testing for Piping Components | | Forged or Rolled 8 and 9% Nickel Alloy | A522/A522M | | Steel Flanges, Fittings, Valves, and Parts | | for Low-Temperature Service | | Forgings, Carbon and Alloy Steel, for Pipe Flanges, | A694/A694M | | Fittings, Valves, and Parts for High-Pressure Transmission Service | | Flanges, Forged, Carbon and Alloy Steel for Low | A707/A707M | | Temperature Service | | Forgings, Carbon Steel, for Piping Components with | A727/A727M | | Inherent Notch Toughness | | Forgings, Titanium-Stabilized Carbon Steel, for | A836/A836M | | Glass-Lined Piping and Pressure Vessel Service |
1.2 In case of conflict between a requirement of the individual product specification and a requirement of this general requirement specification, the requirements of the individual product specification shall prevail over those of this specification. 1.2 By mutual agreement between the purchaser and the supplier, additional requirements may be specified (see section 4.1.2). The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order as agreed upon between the purchaser and supplier. 1.3 The values stated in either inch-pound units or SI units (metric) are to be regarded separately as standard. Within the text and the tables, 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. |
