17、f this specification.6. General Requirements6.1 WorkmanshipThe pipe and fittings shall be homog-enous throughout and essentially uniform in color, opacity,density, and other properties. The inside and outside surfacesshall be semimatte or glossy in appearance (depending on thetype of plastic) and fr

18、ee of chalking, sticky, or tacky material.The pipe and fitting walls shall be free of cracks, holes, blisters,voids, foreign inclusions, or other defects that are visible to thenaked eye and that may affect the wall integrity. Holesdeliberately placed in perforated pipe are acceptable. Thesurface sh

19、all be free of excessive bloom. Bloom or chalkingmay develop in pipe exposed to the direct rays of the sun(ultraviolet radiant energy) for extended periods; consequently,these requirements do not apply to pipe and fittings afterextended exposure to direct rays of the sun.NOTE 2Wall thickness may var

20、y within each corrugation. Variation isacceptable provided the tubing meets all physical requirements.7. Detail Requirements7.1 General:7.1.1 The following requirements shall be met by perforatedor nonperforated pipe, as applicable.7.1.2 Individual results shall be used to determine compli-ance with

There shall be no separationof layers when the pipe is deflected 20 %, in accordance withTest Method D2412, nor shall it be possible to separate thelayers with the point of a knife when the pipe is in the deflectedcondition.NOTE 3This test may be conducted as a continuation

27、 of pipe stiffnesstesting as specified in 9.5.NOTE 4Until an ASTM specification for an acceptable stress-cracktest is published, environmental stress cracking should be evaluated by theuser on the basis of data furnished by the manufacturer.7.8 Fitting Requirements:7.8.1 The fittings shall not reduc

28、e or impair the overallintegrity or function of the pipe line.NOTE 5Common corrugated fittings include in-line joint fittings, suchas tees, Ys, reducers, couplers, elbows, and end caps. These fittings areinstalled internally or externally by various methods, such as snap-on,V-insertion, screw-on, or

29、 wrap around.NOTE 6Some corrugated fittings will not fit all pipe. Only fittingssupplied or recommended by the pipe manufacturer should be used.7.8.2 Joints made with couplers, installed in accordancewith the manufacturers instructions, shall not separate whentested in accordance with 9.8.7.8.3 Fitt

30、ing specimens shall not crack or split when testedin accordance with 9.9.8. Sampling and Retest8.1 SamplingSamples of pipe and fittings sufficient todetermine conformance with this specification shall be taken atrandom from stock by the testing agency.

31、ype under consideration.8.2 Retest and RejectionIf any test failure occurs, the pipeor fitting may be retested to establish conformity. The test shallbe repeated on two additional samples from the same lot orshipment. If either of these two additional samples fail, the pipeor fitting does not comply

32、 with this specification.9. Test Methods9.1 Conditioning Test SpecimensCondition the specimenprior to test at 73.4 6 3.6F 23 6 2C and 50 6 5 % relativehumidity for not less than 40 h prior to the test, in accordancewith Procedure A in Practice D618 for those tests whereconditioning is required, unle

33、ss otherwise specified.9.2 Test ConditionsConduct tests in laboratory atmo-sphere of 73.4 6 3.6F 23 6 2C and 50 6 5 % relativehumidity, unless otherwise specified.9.3 Inside DiameterMeasure the inside diameter of three1-ft 300-mm specimens, with any suitable device accurate toF667/F667M 1526132 in.

Make all measurements onthe pipe while it is resting on a relatively flat surface, in astraight lin

35、e, with no external tensile or compressive forcesexerted on the pipe.9.5 Pipe StiffnessSelect a minimum of three pipe speci-mens and test for pipe stiffness F/y, as described in TestMethod D2412, except for the following conditions: (1) Thetest specimens shall be at least as long as the outside diam

39、ch resistance. Subject each testspecimen to a longitudinal stretching force equal to 5 lb/in. ofnominal inside diameter to a maximum of 50 lb, excluding theweight of the specimen. Hang the specimens in a verticalmanner with the test force applied as a dead (hanging) weightto the bottom end of the pi

40、pe. The gauge length for determiningpercent elongation shall be the middle 3-ft 1-m portion of theunstretched specimen.
