16、acturers own production of the product, maybe used by the manufacturer provided that the tubing andfittings produced meet all requirements of this specification.6. General Requirements6.1 WorkmanshipThe pipe and fittings shall be homog-enous throughout and essentially uniform in color, opacity,densi
17、ty, and other properties. The inside and outside surfacesshall be semimatte or glossy in appearance (depending on thetype of plastic) and free 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 a
18、re visible to thenaked eye and that may affect the wall integrity. Holesdeliberately placed in perforated pipe are acceptable. Thesurface shall 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; con
19、sequently,these requirements do not apply to pipe and fittings afterextended exposure to direct rays of the sun.NOTE 3Wall thickness may vary within each corrugation. Variation isacceptable provided the tubing meets all physical requirements.7. Detail Requirements7.1 General:7.1.1 The following requ
20、irements shall be met by perforatedor nonperforated pipe, as applicable.7.1.2 Individual results shall be used to determine compli-ance with the requirements, unless otherwise stated.7.2 Dimensions and Tolerances:7.2.1 Pipe:7.2.1.1 Nominal DiameterThe nominal diameter of thepipe shall be the average

There shall be no separationof layers when the pipe is deflected 20 %, in accordance withTest Method D 2412, nor shall it be p
26、ossible to separate thelayers with the point of a knife when the pipe is in the deflectedcondition.NOTE 4This test may be conducted as a continuation of pipe stiffnesstesting as specified in 9.5.NOTE 5Until an ASTM specification for an acceptable stress-cracktest is published, environmental stress c
27、racking 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 reduce or impair the overallintegrity or function of the pipe line.NOTE 6Common corrugated fittings include in-line joint fittings, suchas tees, Ys, reducer
28、s, couplers, elbows, and end caps. These fittings areinstalled internally or externally by various methods, such as snap-on,V-insertion, screw-on, or wrap around.NOTE 7Some corrugated fittings will not fit all pipe. Only fittingssupplied or recommended by the pipe manufacturer should be used.7.8.2 J
29、oints made with couplers, installed in accordancewith the manufacturers instructions, shall not separate whentested in accordance with 9.8.7.8.3 Fitting specimens shall not crack or split when testedin accordance with 9.9.8. Sampling and Retest8.1 SamplingSamples of pipe and fittings sufficient tode
30、termine conformance with this specification shall be taken atrandom from stock by the testing agency. Samples shall berepresentative of the product type under consideration.8.2 Retest and RejectionIf any test failure occurs, the pipeor fitting may be retested to establish conformity. The test shallb
31、e repeated on two additional samples from the same lot orshipment. If either of these two additional samples fail, the pipeor fitting does not comply 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 % relati
32、vehumidity for not less than 40 h prior to the test, in accordancewith Procedure A in Practice D 618 for those tests whereconditioning is required, unless 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 oth
33、erwise specified.9.3 Inside DiameterMeasure the inside diameter of three1-ft (300-mm) specimens, with any suitable device accurate to6132 in. (0.8 mm), at two positions, namely, the block seamand 90 from the block seams, and average the six measure-ments.9.4 LengthMeasure pipe with any suitable devi
34、ce accu-rate to 6132 in. in 10 ft (1 mm in 3 m). Make all measurementsF667062on the pipe while it is resting on a relatively flat surface, in astraight line, with no external tensile or compressive forcesexerted on the pipe.9.5 Pipe StiffnessSelect a minimum of three pipe speci-mens and test for pip
35、e stiffness F/Dy, as described in TestMethod D 2412, except for the following conditions: (1) Thetest specimens shall be at least as long as the outside diameter;the exact length shall be an integer multiple of corrugationpitch. (2) Locate the first specimen of all tubularly extrudedpipe in the load
36、ing machine with the imaginary line betweenthe two corrugator seams (end view) parallel to the loadingplates. The specimen must lay flat on the plate within18 in. (3mm) and may be straightened by hand bending at roomtemperature. Use the first location as a reference point forrotation of the other tw
37、o specimens. Rotate the second speci-men 45 and the third specimen 90. Test each specimen in oneposition only. (3) The deflection indicator shall be readable andaccurate to 60.001 in. (60.02 mm). (4) The parallel platesmust exceed the samples in length. (5) If the pipe under test hasselfcoupling end
38、 sections, include a selfcoupling assembly asone of the three test lengths.9.6 ElongationTest a minimum of three specimens, each60 in. (1.5 m) in length, for stretch resistance. Subject each testspecimen to a longitudinal stretching force equal to 5 lb/in. ofnominal inside diameter to a maximum of 5
39、0 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 pipe. The gage length for determiningpercent elongation shall be the middle 3-ft (1-m) portion of theunstretched specimen. Apply the test w
40、eight gently, and allowit to remain for 3 min; then quickly measure the gage length tothe nearest 0.125 in. (3 mm) to determine elongation. Calculateelongation ( E) as follows:E, % 5elongation 3 100gage lengthCalculate the average of the three values.9.7 Pipe Stiffness While Elongated Test three 30-
41、in.(762-mm) gage lengths cut from the centers of the 60-in.(1.5-m) specimens for pipe stiffness at 5 and 10 % deflection asdescribed in Test Method D 2412, except for the followingconditions: (1) stretch the test specimen as shown in Fig. 1 tothe same percent elongation as determined in 9.6 and test
42、 inthis condition; (2) support the test specimen on a rigid baseplate 12 in. (305 mm) in length; and (3) apply a load plate 12in. (305 mm) in length to the center portion of the 30-in.(760-mm) specimen.9.8 Joint-Separation TestRepeat the elongation test speci-fied in 9.6 on two specimens with a coup
43、ling in the center ofthe specimens. Separation shall be considered a failure. Gagelength and stretch are omitted in this test.9.9 BrittlenessTest pipe and fitting specimens in accor-dance with Test Method D 2444, except six specimens shall betested. Use Tup B weighing 5.5 lb (2.5 kg); the height of
44、thedrop shall be 5 ft (1.5 m). Use a flat-plate specimen holder.Condition the specimens for 24 h at a temperature of 25 63.6F (3.9 6 2C), and conduct all tests within 60 s ofremoval from this atmosphere. The center of the falling tupshall strike on a corrugation crown for three specimens andbetween
