24、l SpecificationVirgin ABS plastic shall con-form to the requirements prescribed in Specification D3965with a cell classification of 4-2-2-2-2. The color and form ofthe material shall be as agreed upon between the seller and thepurchaser in accordance with Specification D3965.5.2 The ABS plastic shal

Use it only in the core layer. The pipeproduced shall meet all the requirements of this s
27、pecification.6. Requirements6.1 GeneralThe pipe and fittings should be homogeneousthroughout and free of 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 re
28、quirements in this section are intended only foruse as quality control tests, not as simulated service tests.6.2 Dimension and Tolerance:6.2.1 Outside DiameterThe outside diameter and toler-ances shall meet the requirements of Table 1 when measured inaccordance with Test Method D2122. The tolerances
29、 forout-of-roundness shall apply to pipe prior to shipment.6.2.2 Wall ThicknessThe wall thickness and tolerancesshall meet the requirements of Table 2 when measured inaccordance with Test Method D2122.6.2.3 LengthThe pipe shall be in either 10 or 20-ft (3.05 or6.1-m) lengths, unless otherwise specif
30、ied. The allowabletolerance on length shall be +12, 0 in. (+12, 0 mm).6.3 Performance Requirements:6.3.1 Pipe StiffnessThe minimum pipe stiffness values at5 % deflection when measured in accordance with Test MethodD2412, shall equal or exceed the values in Table 3. The rate ofcrosshead motion shall
31、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 meets this requirement. If one or twofail, additional testing shall be conducted in accordance with6.3.1.1. If all three fail, the sample does not meet therequirement.6.3.1.1 Pi

33、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 Students “t” distribution, with N-1 de-grees of freedom, where N is the n
34、umber of specimens. Thecritical t value shall be used to at least three significant digits.Alternatively, if the LCL exceeds 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 in
35、clude the three tested under 6.3.1, andan additional eight with rotation by 35, as specified in TestMethod D2412, continuing throughout the remaining speci-mens.6.3.1.2 The LCL based on testing eleven specimens iscalculated as follows:LCL 5 avg PS! 2 $2.76std. dev.!/= N!%where: avg PS! 5 (PSi!#/11!

37、convenience, should not be considered as a limitation withrespect to in-use deflection. The engineer is responsible for establishingthe acceptable deflection limit.NOTE 5The strength and load-carrying capabilities of plastic pipe aremeasured and reported as pipe stiffness, which is determined in acc
38、or-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 the term derives from rigid pipe and refers to its ultimatestrength at rupture.6

Threespecimens shall be tested; all shall meet the requirements.Failure shall be a crack or break extending entirely through thepipe
