24、for the drainage and venting ofsewage and certain other non-hazardous liquid wastes.NOTE 1Before installing pipe for waste disposal use, the approval of the cognizant building code authority should be obtained as conditions notcommonly found in normal use may be encountered and temperatures in exces
25、s of 180F (82C) may be encountered.NOTE 2This specification does not include requirements for pipe intended to be used to vent combustion gases.5. Materials5.1 Material SpecificationVirginABS plastic shall conform to the requirements prescribed in Specification D3965 with a cellclassification of 4-2
26、-2-2-2. The color and form of the material shall be as agreed upon between the seller and the purchaser inaccordance with Specification D3965.5.2 The ABS plastic shall conform to the following requirements:5.2.1 Acrylonitrile-Butadiene-Styrene (ABS) PlasticPlastic shall contain a minimum of 15 % acr
27、ylonitrile, 6 % butadiene, and15 % styrene or substituted styrene, or both, of polymers or blends of polymers.5.2.2 ABS plastic shall contain no more than 10 % of other monomeric or polymeric components plus other necessarycompounding ingredients.5.3 Rework MaterialThe manufacturer shall use only hi
28、s own clean rework pipe material conforming with these cell classrequirements. Use it only in the core layer. The pipe produced shall meet all the requirements of this specification.6. Requirements6.1 GeneralThe pipe and fittings should be homogeneous throughout and free of visible cracks, holes, fo
29、reign inclusions, orother injurious defects. The pipe shall be as uniform as commercially practicable in color, opacity, density, and other physicalproperties.4 Available from Standardization Documents Order Desk, DODSSP, Bldg. 4, Section D, 700 Robbins Ave., Philadelphia, PA 19111-5098, http:/www.d

31、h Test Method D2122. The tolerances for out-of-roundness shall apply to pipe prior to shipment.6.2.2 Wall ThicknessThe wall thickness and tolerances shall meet the requirements of Table 2 when measured in accordancewith Test Method D2122.6.2.3 LengthThe pipe shall be in either 10 or 20-ft (3.05 or 6
32、.1-m) lengths, unless otherwise specified. The allowable toleranceon length shall be +12, 0 in. (+12, 0 mm).6.3 Performance Requirements:6.3.1 Pipe StiffnessThe minimum pipe stiffness values at 5 % deflection when measured in accordance with Test MethodD2412, shall equal or exceed the values in Tabl
33、e 3. The rate of crosshead motion shall be 0.20 to 0.25 in./min (5.1 to 6.3 mm/min).Three specimens shall be tested. If all three meet this requirement, the sample meets this requirement. If one or two fail, additionaltesting shall be conducted in accordance with 6.3.1.1. If all three fail, the samp
34、le does not meet the requirement.6.3.1.1 Pipe Stiffness and Lower Confidence LimitIn the event that one or two of the specimens tested in 6.3.1 fail to meetthe minimum requirement, the average pipe stiffness of eleven specimens shall meet or exceed the minimum requirement givenin Table 3. The 99 % l
35、ower confidence limit (LCL) shall be within 15 % of the average value. The LCL shall be calculated usingthe Students “t” distribution, with N-1 degrees of freedom, where N is the number of specimens. The critical t value shall be usedto at least three significant digits. Alternatively, if the LCL ex
36、ceeds the minimum pipe stiffness requirement in Table 3, but is notwithin 15 % of the average, the sample meets the requirements of the Pipe Stiffness testing. The eleven specimens include the threetested under 6.3.1, and an additional eight with rotation by 35, as specified in Test Method D2412, co
37、ntinuing throughout theremaining specimens.6.3.1.2 The LCL based on testing eleven specimens is calculated as follows:LCL5avg PS!2$2.76std. dev.!/=N!%where:avg PS!5(PSi!#/11!

38、3For quality control testing, a single specimen may be used with the thinnest wall at the top.NOTE 4The 5 % deflection criterion, which was arbitrarily selected for testing convenience, should not be considered as a limitation with respect toin-use deflection. The engineer is responsible for establi
39、shing the acceptable deflection limit.NOTE 5The strength and load-carrying capabilities of plastic pipe are measured and reported as pipe stiffness, which is determined in accordancewith Test Method D2412. The term “crush strength” is not applicable to plastic piping because the values obtained can
40、be significantly different,depending on the bedding, loading, or testing technique used, and the term derives from rigid pipe and refers to its ultimate strength at rupture.6.3.2 Pipe FlatteningThere shall be no evidence of rupture when pipe is deflected 25 % of the initial inside diameter whenteste
41、d in accordance with Test Method D2412. Three specimens shall be tested; all shall meet the requirements. Failure shall bea crack or break extending entirely through the pipe wall visible to the unaided eye.6.3.3 Impact StrengthThe minimum impact resistance, when tested at the time of manufacture, s
