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 A 105/A 105M Forgings, Carbon Steel, for General-Purpose Piping A 181/A 181M Forged or Rolled Alloy-Steel Pipe Flanges, Forged A 182/A 182M Fittings, and Valves and Parts for High Temperature
Service Forgings, Carbon and Low Alloy Steel, Requiring Notch A 350/A 350M Toughness Testing for Piping Components Forged or Rolled 8 and 9 % Nickel Alloy A 522/A 522M Steel Flanges, Fittings, Valves, and Parts for Low-Temperature Service Forgings, Carbon and Alloy Steel, for Pipe Flanges, A 694/A 694M Fittings, Valves, and Parts for High-Pressure
Transmission Service Flanges, Forged, Carbon and Alloy Steel for Low A 707/A 707M Temperature Service Forgings, Carbon Steel, for Piping Components with A 727/A 727M Inherent Notch Toughness Forgings, Titanium-Stabilized Carbon Steel, for A 836/A 836M 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.

1.3 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.

1.4 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.
