Scope of standard 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: Title of Specification ASTM Designation Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and Elevated Temperatures A234/A234M Specification for Wrought Austenitic Stainless Steel Piping Fittings A403/A403M Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Low-Temperature Service A420/A420M Specification for Butt-Welding, Wrought-Carbon Steel, Piping Fittings with Improved Notch Toughness A758/A758M Specification for As-Welded Wrought Austenitic Stainless Steel Fittings for General Corrosive Service at Low and Moderate Temperatures A774/A774M Specification for Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fittings A815/A815M Specification for Heat-Treated Carbon Steel Fittings for Low-Temperature and Corrosive Service A858/A858M Specification for Wrought High-Strength Low-Alloy Steel Butt-Welded Fittings A860/A860M 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.
