There shall be no separation oflayers when the pipe is deflected 20 %, in accordance with Test Method D2412, nor shall it be possible to separate the layers withthe point of a knife when the pipe is in the def
31、lected condition.NOTE4This 3This test may be conducted as a continuation of pipe stiffness testing as specified in 9.5.NOTE5Until 4Until an ASTM specification for an acceptable stress-crack test is published, environmental stress cracking should be evaluated bythe user on the basis of data furnished
32、 by the manufacturer.F667 1227.8 Fitting Requirements:7.8.1 The fittings shall not reduce or impair the overall integrity or function of the pipe line.NOTE6Common 5Common corrugated fittings include in-line joint fittings, such as tees, Ys, reducers, couplers, elbows, and end caps. Thesefittings are
33、 installed internally or externally by various methods, such as snap-on, V-insertion, screw-on, or wrap around.NOTE7Some 6Some corrugated fittings will not fit all pipe. Only fittings supplied or recommended by the pipe manufacturer should be used.7.8.2 Joints made with couplers, installed in accord
34、ance with the manufacturers instructions, shall not separate when tested inaccordance with 9.8.7.8.3 Fitting specimens shall not crack or split when tested in accordance with 9.9.8. Sampling and Retest8.1 SamplingSamples of pipe and fittings sufficient to determine conformance with this specificatio
35、n shall be taken at randomfrom stock by the testing agency. Samples shall be representative of the product type under consideration.8.2 Retest and RejectionIf any test failure occurs, the pipe or fitting may be retested to establish conformity. The test shallbe repeated on two additional samples fro
36、m the same lot or shipment. If either of these two additional samples fail, the pipe orfitting does not comply with this specification.9. Test Methods9.1 Conditioning Test SpecimensCondition the specimen prior to test at 73.4 6 3.6F (23 6 2C) and 50 6 5 % relativehumidity for not less than 40 h prio
