2, the side of the specimen turned toward the gap of the jig shall be the face for face-bend specimens, the root for root-bend specimens, and the side with the greater discontinuities, if any, for side-bend specimens. The specimen shall be forced into the die by applying load on the plunger until the curvature of the specimen is such that a 1 ⁄8 in. 2) is used. 3), the side of the specimen turned toward the roller shall be the face for face-bend specimens, the root for root-bend specimens, and the side with the greater discontinuities, if any, for side-bend specimens.

2 and polished for examination. All flash shall be removed from the strips and the welds shall be visually examined per QW-194. Half of the strips from each pipe specimen shall then be prepared as root bend specimens and the remaining strips shall be prepared as face bend specimens in accordance with QW-160. The specimens shall be tested in accordance with QW-160, except for the following: (a) For P-No. 1) shall be three times the thickness of the specimen. (b) In lieu of QW-163, the sum of lengths of individual open flaws on the convex surface of all the bend test specimens taken from each pipe individually shall not exceed 5% of the outside circumference of that test pipe.

1(f). 1 General. Drop weight tests shall be made when required by other Sections. Test procedures and apparatus shall conform to the requirements of ASTM Specification E 208. 1 Production Assembly Mockups. 2. (a) Plate-to-Shape (1) The mockup for plate-to-shape shall be cut transversely to provide three approximately equal test specimens not to exceed approximately 2 in. (50 mm) in length. The test specimen that contains the start and stop of the weld shall be fracture tested in accordance with QW-182.
