The pipe or fittings producedshall meet all the requirements of this specification.6. Requirements6.1 GeneralThe pipe and fittings shall be homogeneousthroughout and free of
26、 visible cracks, holes, foreign inclusions,or other injurious defects. The pipe shall be as uniform ascommercially practicable in color, opacity, density, and otherphysical properties.6.1.1 The requirements in this section are intended only foruse as quality control tests, not as simulated service t

33、of the specimens tested in 6.3.1 fail tomeet the minimum requirement, the average pipe stiffness ofeleven specimens shall meet or exceed the minimum require-ment given in Table 3. The 99 % lower confidence limit (LCL)shall be within 15 % of the average value. The LCL shall becalculated using the Stu
34、dents “t” distribution, with N-1 de-grees of freedom, where N is the number of specimens. Thecritical t value shall be used to at least three significant digits.Alternatively, if the LCLexceeds the minimum PS requirementin Table 3, but is not within 15 % of the average, the samplemeets the requireme
35、nts of the Pipe Stiffness testing. The elevenspecimens include the three tested under 6.3.1, and an addi-tional eight with rotation by 35, as specified in Test MethodD2412, continuing throughout the remaining specimens.6.3.1.2 The LCL based on testing eleven specimens iscalculated as follows:LCL 5av

37、iteria is arbitrarily selected for testingconvenience. It should not be considered as a limitation with respect toin-use deflection. The engineer is responsible for establishing the accept-able deflection limit.NOTE 5The strength and load-carrying capabilities of plastic pipe aremeasured and reporte
38、d as pipe stiffness, which is determined in accor-dance with Test Method D2412. The term “crush strength” is notapplicable to plastic piping because the values obtained can be signifi-cantly different, depending on the bedding, loading, or testing techniqueused, and because the term derives from rig
39、id pipe and refers to itsultimate strength at rupture.6.3.2 Pipe FlatteningThere shall be no evidence of rup-ture when pipe is deflected 40% of the initial inside diameterwhen tested in accordance with Test Method D2412. The rateof head approach shall be 0.20 to 0.25 in./min (5.1 to 6.3mm/min). Thre
40、e specimens shall be tested. All shall meet therequirements. Failure shall be a crack or break extendingentirely through the pipe wall visible to the unaided eye.6.3.3 Impact ResistanceThe minimum impact resistance,when tested at the time of manufacture, shall comply withTable 4. Test in accordance
41、with Test Method D2444 using TupB and Holder B. Use a 30-lb (13.6 kg) tup for testing all pipesizes.6.3.3.1 Test 10 specimens. When 9 or 10 specimens pass,accept the lot. When 2 or more specimens fail, test 10additional specimens. When 17 of 20 specimens tested pass,accept the lot. When 4 or more of
42、 20 specimens fail, test 20additional specimens. When 32 of 40 specimens pass, acceptthe lot. When 9 or more of 40 specimens fail, the lot does notmeet the requirements of this specification.6.3.3.2 Failure of the test specimen shall be shattering orany crack or break extending entirely through the
43、pipe wall andvisible to the unaided eye.6.4 Coextruded Pipe:6.4.1 Thickness of Outer LayerFor pipe produced by thecoextrusion process, that is, pipe containing two or moreconcentric layers, the outer layer shall be at least 0.020 in.(0.50 mm) thick and shall contain pigments or screening agentsto pr
