Die Annotation des Normtextes ASTM A960/A960M-23 :
This specification covers the common requirements that shall apply to wrought steel piping fittings. The material shall consist of forgings, bars, plates, and seamless or welded tubular products. Ferritic steels shall be fully killed. Hollow cylindrically shaped parts up to and including NPS 4 may be machined from bar or seamless tubular material. Elbows, return bends, tees, and header tees shall not be machined directly from bar stock. The following procedures shall be done for heat treatment: full annealing, solution annealing, isothermal annealing, normalizing, tempering and post-weld heat treatment, stress relieving, and quench and temper. Chemical analysis, heat analysis, and product analysis shall also be done. The chemical requirements shall conform to the required compositions of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, columbium, titanium, aluminum, lead, and copper. The following tests shall be done for the mechanical requirements: tension, hardness, impact, and hydrostatic tests.

1.1?This specification covers a group of common requirements that shall apply to wrought steel piping fittings covered in any of the following individual product specifications or any other ASTM specification that invokes this specification or portions thereof:
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 4.1.8). 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 by 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 specification. 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. |
