Requirements6.1 GeneralThe pipe and fittings should be homogeneousthroughout and free of visible cracks, holes, f

26、oreign 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 tests.6.2 Dimension and To

The rate ofcrosshead motion shall be 0.20 to 0.25 in./min (5.1 to 6.3mm/min). Three specimens shall be tested. If all three meet thisrequirement, the sample me

30、ets this requirement. If one or twofail, additional testing shall be conducted in accordance with6.3.1.1.

34、 confidence limit (LCL)shall be within 15 % of the average value. The LCL shall becalculated using the Students “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 LCL exceeds

35、 the minimum pipe stiffnessrequirement in Table 3, but is not within 15 % of the average,the sample meets the requirements of the Pipe Stiffness testing.The eleven specimens include the three tested under 6.3.1, andan additional eight with rotation by 35, as specified in TestMethod D 2412, continuin

37、E 3For quality control testing, a single specimen may be usedwith the thinnest wall at the top.NOTE 4The 5 % deflection criterion, which was arbitrarily selectedfor testing convenience, should not be considered as a limitation withrespect to in-use deflection. The engineer is responsible for establi

38、shingthe acceptable deflection limit.NOTE 5The strength and load-carrying capabilities of plastic pipe aremeasured and reported as pipe stiffness, which is determined in accor-dance with Test Method D 2412. The term “crush strength” is notapplicable to plastic piping because the values obtained can

39、be signifi-cantly different, depending on the bedding, loading, or testing techniqueused, and the term derives from rigid pipe and refers to its ultimatestrength at rupture.6.3.2 Pipe FlatteningThere shall be no evidence of rup-ture when pipe is deflected 25 % of the initial inside diameterwhen test

When 2 or more specimens fail,

42、test 10additional specimens. When 17 of 20 specimens tested pass,accept the lot. When 4 or more of 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 Fai

43、lure of the test specimen shall be shattering orany crack or break extending entirely through the pipe wall andvisible to the unaided eye.6.3.4 BondThe bond between layers shall be strong anduniform. It shall not be possible to separate any two layers witha probe or point of a knife blade so that th

44、e layers separatecleanly, or so the probe or knife blade moves freely betweenthe layers; nor shall separation of bond occur between layersduring testing performed under the requirements of this speci-fication.6.3.5 Pigments or Screening AgentsThe ABS compoundused in the outer layer shall contain pig
