Test Methods7.1 SamplingTake a random sample from each lot orshipment of the pipe and fittings sufficient to determineconformance with this specification.About 40 ft (12 m) of pipeare required to make the tests prescribed. The number offittings required varies depending on
41、 the size and type offitting.7.2 Conditioning7.2.1 For referee testing at 73F, condition the specimensprior to test at 73.4 6 3.6F (23 6 2C) and 50 6 5 % relativehumidity in accordance with Practice D618, Procedure A.7.2.2 For routine quality control testing at 73F, conditionthe specimens at the tem
42、perature and humidity of the manu-facturers testing facility for not less than1horuntil thespecimens are at the room temperature.7.3 Test Conditions7.3.1 For referee purposes, conduct tests in the standardlaboratory atmosphere of 73.4 6 3.6F (23 6 2C) and 50 65 % relative humidity.7.3.2 For routine
43、quality control testing, conduct tests at thetemperature and humidity of the manufacturers testing area.7.4 Deflection Load and Crush ResistanceMeasure thedeflection load and crush resistance of pipe and fittings inaccordance with Test Method D2412. In the test for pipe notethe load when the initial
44、 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). The rate of head approach shall be 0.20 to0.25 in./min (5.1 to 6.4 mm/min). Each specimen shall meetthe requirements of 6
45、.3.1.7.4.1 Fitting Test SpecimensTest three complete fittings.Shim fittings to give full centerline contact with platens.Fittings having nonuniform diameters such as reducers shall beconsidered acceptable when the wall thickness at all points isequal to or greater than the wall thickness of pipe of
46、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 pipe test specimens is reduced to 40 % of its originalvalue or the pipe cracks or shows other visible evidenc
47、e 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. Recordlocation and type of failure.7.4.3 CalculationFor pipe, divide the load in pounds-force or newtons at 15 % def
48、lection (deflection load) and alsoat failure (crush resistance), if such occurred, by the length ofthe pipe test specimen in feet or metres to obtain the deflectionload and crush resistance, respectively, in pounds per linearfoot, or newtons per metre. For pipe stiffness, divide the loadin pounds-fo
49、rce 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 test results for each specimen forconformance to the requirements of 6.3.1 and 6.3.2.TABLE 5 3.25-in. Outside Diameter Reducing Sanitary Tee and 45 Wyes, in.
