32、6.3.1 fail tomeet the minimum requirement, the average pipe stiffness of11 specimens shall meet or exceed the minimum requirementgiven in Table 2. The 99% lower confidence limit (LCL) shallbe within 15% of the average value. The LCL shall becalculated using the Students “t” distribution, with N-1 de
33、-grees of freedom, where N is the number of specimens (11).The critical t value shall be used to at least three significantdigits. Alternatively, if the LCL exceeds the minimum PSrequirement in the applicable table but is not within 15% of theaverage, the sample meets the requirements of the pipesti

The 11 specimens include the three testedunder 6.3.1 and an additional eight with rotation by 35, asspecified in Test Method D2412, continuing throughout theremaining specimens.6.3.1.2 The LCL based on testing eleven specimens iscalculated as follows:LCL 5 avgPS! 2 $2.76 std. dev.!=N

When 9 or more of 40 specimens fail, the lot does notmeet the requirements of this specification.6.3.3.2 Failure of the test specimen shall be shattering orany crack or break extending entirely through the pipe wall andvisible to the unaided eye.
41、6.3.4 BondThe bond between layers shall be strong anduniform. It shall not be possible to separate any two layers witha probe or the point of a knife blade so that the layers separatecleanly, nor shall separation of the bond occur between layersduring testing performed under the requirements of this

The test sample shall be 18 60.1 in. (457 6 3 mm)
43、 long. Create a seal on the O.D. and theI.D. of the pipe near one end in a manner that permits theexposed core to be subjected to water pressure (Note 6). Anysign of water emanating from the core at the opposite end after30 minutes is indication of an open cell structure and thespecimen does not mee
44、t the requirements of this specification.NOTE 6The method of sealing against the I.D. and O.D. of the pipe isnot specified, as several acceptable methods are available. One suchmethod uses an elastomeric no-hub adapter clamped to the O.D. andpneumatic or mechanical test plug to seal the I.D.6.4 Othe
