4.1.1 In addition, test the pipe designs covered by Tables 706.02-1, 706.02-
2, 706.02-3, and 706.02-4 and ASTM C 76 (ASTM C 76M), Tables 2 through 5,
and interpolated designs by the three-edge bearing method. When the test load on
the pipe reaches 115 percent of the required 0.01-inch (0.3 mm) crack D-load
without developing a 0.01-inch (0.3 mm) or larger crack, accept the test specimen
for strength. If any test specimen fails to pass this test, but attained the 0.01-inch
(0.3 mm) crack, continue the test until the ultimate D-load is reached.
4.1.2 In addition, accept pipe 54 inches (1350 mm) and larger in diameter
covered by Tables 706.02-1, 706.02-2, 706.02-3, and 706.02-4, and ASTM C 76
(ASTM C 76M), Tables 2 through 5, and interpolated designs according to Section
12 and the following requirements:
1. When pipe from a plant has been approved by the Laboratory for
a specified design and pipe from the same plant has wall and steel area not less
than the approved pipe.
