Test:
1. The test specimens and the tests required by this specification shall conform to those described in the latest issue of Test Methods and Definitions A 370.
2. The longitudinal tension test specimen shall be taken from the end of the pipe or, for continuous-welded pipe, it shall be permissible to be taken from the skelp, ata point approximately 90° from the weld, and shall not be flattened between gage marks. The sides of each specimen shall be parallel between gage marks. If desired, the tension tests are permitted to be made on the full section of pipe. When impracticable to pull a test specimen in full section,
the standard 2-in. [50-mm] gage length tension test speci-men shown in Fig. A2.3 of Test Methods and Definitions
A 370 is acceptable.
3. Transverse weld test specimens from electric-resistance-welded pipe shall be taken with the weld at the center of the specimen. All transverse test specimens shall be approximately 1 1⁄2in. [40 mm] wide in the gage length and shall represent the full wall thickness of the pipe from which the specimen was cut.
4. Test specimens for the bend and flattening tests shall be taken from pipe. Test specimens for the flattening test shall be smooth on the ends and free from burrs.
5. All specimens shall be tested at room temperature.
