Common Requirements5.1 Bolting supplied to this specification

16、 shall conform tothe requirements of SpecificationA962/A962M. These require-ments include test methods, finish, thread dimensions, mark-ing, certification, optional supplementary requirements, andothers. Failure to comply with the requirements of Specifica-tionA962/A962M constitutes nonconformance w

17、ith this speci-fication. In case of conflict between the requirements of thisspecification and SpecificationA962/A962M, this specificationshall prevail.6. Materials and Manufacture6.1 Finishing Process:6.1.1 Threads may be formed by machining or rolling.Threads may be formed after precipitation heat

18、 treatment orafter solution anneal but prior to precipitation heat treatment.Type designations are as follows:Type M1threads formed by machining after precipitationheat treatment.Type M2threads formed by machining after solutionanneal but prior to precipitation heat treatment.Type R1threads formed b

The rupture shall occur in the smooth section of thebar.8.2.4.3 As an alternative procedure and, when specificallyapproved by the purchaser, separate smooth and notched testspecimens, machined from adjacent sections of the sam

27、e piece,with gage sections conforming to the respective dimensions ofTable 7, may be tested under the above conditions. The notchedspecimen need not be tested to rupture but shall not rupture inless time than the companion smooth specimen.8.2.4.4 When the minimum specified time to rupture inTable 6

28、has been achieved, incremental loading may be used toaccelerate the time to rupture. At intervals of 8 to 16 h,preferably 8 to 10 h, the stress shall be increased in incrementsof 5000 psi 34.5 MPa. Rupture location, and elongationrequirements shall be as prescribed in Table 6, 8.2.4.2, and8.2.4.3.8.
