The allowablet
31、olerance on length shall be +12, 0 in. (+12, 0 mm).6.3 Performance Requirements:6.3.1 Pipe Stiffness The 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 be 0.20 to 0.25 in
32、./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 Pipe Stiffness and L
33、ower Confidence LimitIn theevent that one or two 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 averag
34、e value. The LCL shall becalculated using the Students “ t” distribution, with N-1degrees 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
35、 % of the average, the samplemeets the requirements 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
36、eleven specimens iscalculated as follows:LCL 5 avg PS! 2 $2.76std. dev.!/=N!% (1)where:avg PS! 5 (PSi!#/11!std. dev.! 5 F(PS22 (PS!2/NN 2 1G1/2N=11.6.3.1.3 The 15 % requirement is calculated as follows:Avg 2 LCL!/Avg! 3100#15% (2)NOTE 3For quality control testing, a single specimen may be usedwith t
37、he thinnest wall at the top.NOTE 4The 5 % deflection criteria 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-carryi
38、ng capabilities of plastic pipe aremeasured and reported 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 testi
39、ng techniqueused, and because the term derives from rigid 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
40、 shall be 0.20 to 0.25 in./min (5.1 to 6.3mm/min). Three 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 man
41、ufacture, shall comply withTable 4. Test in accordance 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
42、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.TABLE 2 Wall Thickness and Tolerance for ABS Schedule
