4,2,3,3 Acceptance Criteria for Bend Tests. The convex surface of the bend test specimen shall be
visually examined for surface discontinuities. For accep tance, the surface shall contain no
discontinuities ex ceeding the following dimensions:
(I) 1/8 in 13 mm] measured in any direction on the surface
(2) 3/8 in [10 mm] the sum of the greatest dimen sions of all discontinuities exceeding 1/32 in [
1 mm], but less than or equal to 1/8 in [3 mmJ
(3) 1/4 in [6 mm]--the maximum corner crack, except when that corner crack results from visible
slag inclusion or other fusion type discontinuity, then the 1/8 in [3 mmJ maximum shall apply
Specimens with corner cracks exceeding 1/4 in [6 mm] with no evidence of slag inclusions or other
fusion type discontinuity shall be disregarded, and a replacement test specimen from the original
weldment shall be tested.
