3、ions. See Specification A962/A962M for thedefinition of bolting.1.2 The following referenced common requirements areindispensable for application of this specification: SpecificationA962/A962M.1.3 Supplementary requirements of an optional nature areprovided for use at the option of the purchaser. Th

4、ese supple-mentary requirements only apply when specified individuallyby the purchaser in the purchase order or contract.1.4 This specification is expressed in both inch-pound unitsand in SI units; however, unless the purchase order or contractspecifies the applicable “M” specification designation (

5、SIunits), inch-pound units shall apply.1.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independ

Ordering Information3.1 The inquiry and orders for material under this specifi-cation shall include the following, as required, to describe thedesired material adequately:3.1.1 Grade and Class3.1.2 Condition (Section 5),3.1.3 Heat treatment (Section 6),3.1.4

8、 Supplementary Requirements (S1 to S9),3.1.5 Reports required (Section 16),3.1.6 End use, and3.1.7 Any special requirements.3.2 The purchaser is referred to the listed supplementaryrequirements.4. Common Requirements4.1 Bolting supplied to this specification shall conform tothe requirements of Speci

9、ficationA962/A962M. These require-ments include test methods, finish, thread dimensions, macroetch, marking, certification, optional supplementary require-ments, and others. Failure to comply with the requirements ofSpecification A962/A962M constitutes nonconformance withthis specification. In case

10、of conflict between this specificationand Specification A962/A962M, this specification shall pre-vail.5. Manufacture5.1 Bolting material shall be supplied hot-rolled or hot-forged or cold-finished at the option of the producer. However,if desired by the purchaser, cold finishing may be specified.6.

11、Heat Treatment6.1 Bolting material ordered in the annealed condition shallhave a structure suitable for machining. Such annealed materialis not intended to be used without subsequent quenching andtempering as specified in 6.21This specification is under the jurisdiction of ASTM Committee A01 on Stee
