24、 not rupture in less than 24 hours. The test shall be continued to rupture without change of load. Elongation after rupture, measured at room temperature, shall be not less than 10% in 2 inches (50.8 mm). Tests shall be conducted in accordance with ASTM E139. 3.3.3.1 For product 0.010 inch (0.25 mm)
25、 and under in nominal thickness, stress rupture properties may be established using a sample up to 0.025 inch (0.64 mm) in nominal thickness from the same master coil and heat. The suppliers certification of test shall indicate the thickness at which the stress rupture test was performed. 3.3.3.2 Th
26、e test of 3.3.3 may be conducted using incremental loading. In such case, the load required to produce an initial axial stress of 24.0 ksi (165 MPa) or higher shall be used to rupture or for 24 hours, whichever occurs first. After the 24 hours and at intervals of 8 to 16 hours thereafter, the stress
27、 shall be increased in increments of 2.0 ksi (14 MPa).
