ICS Code (Iron and steel pipes): | 23.040.10 |
scope:
1.1 This specification covers a number of grades of nominal-wall-thickne
Note 1--TP329 (S32900) formerly in this specification, has been transferred to Specifications A789/A789M and A790/A790M.
1.2 An optional supplementary requirement is provided, and when desired, shall be so stated in the order.
Note 2--For tubing smaller than 1/2 in. [12.7 mm] in outside diameter, the elongation values given for strip specimens in shall apply. Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in outside diameter or with walls thinner than 0.015 in. [0.4 mm].
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
