Each specimen shall meet the requirements of 6.3.2.7.4.2 ProcedureTerminate the test when the inside diam-et
44、er of pipe 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. R
