Scope

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. 1.3  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 SI units or inch-pound units 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 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. 1.5  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
