(+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 equ

34、al or exceed the values in Table 3. 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 meets this requirement. If one or twofail, additional testing shall be conducted in accordance with6.3.1.1.

35、 If all three fail, the sample does not meet therequirement.6.3.1.1 Pipe Stiffness and Lower 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 g

36、iven 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-1degrees of freedom, where N is the number of specimens. Thecritical t value shall be used to at least three significant digits.Alt

37、ernatively, if the LCLexceeds the minimum PS requirementin Table 3, but is not within 15 % 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 Meth

38、odD2412, continuing throughout the remaining specimens.6.3.1.2 The LCL based on testing 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!

It should not be considered as a limitation with respect toin-use deflection. The engineer is responsi

40、ble for establishing the accept-able 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 D2412. The term “crush strength” is notapplicable to plastic piping because the valu

41、es obtained can be signifi-cantly different, depending on the bedding, loading, or testing 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 i

42、nside 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). 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

43、 eye.6.3.3 Impact ResistanceThe minimum impact resistance,when tested at the time of manufacture, 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,ac

44、cept 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 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 r
