In the test for pipe notethe load when the initial inside diameter is reduced by 5 %(pipe stiffness), by 15 % (deflection load), and continue the testuntil the diameter is reduced by 60 % of its original value(crush resistance).

43、 acceptable when the wall thickness at all points isequal to or greater than the wall thickness of pipe of the samematerial and diameter that meets the crush resistance require-ments. Each specimen shall meet the requirements of 6.3.2.7.4.2 ProcedureTerminate the test when the inside diam-eter of pi

44、pe test specimens is reduced to 40 % of its originalvalue or the pipe cracks or shows other visible evidence offailure. Terminate the test on fittings when the load reaches1000 lbf/ft (1350 N/m) of centerline length. Observe the loadand deflection at the first evidence of cracking, if any. Recordloc

46、spectively, in pounds per linearfoot, or newtons per metre. For pipe stiffness, divide the loadin pounds-force or newtons at 5 % deflection by the specimenlength in inches or metres and then divide by the deflection ininches or metres. Calculate the values for each specimenseparately. Examine the te
