28、essThe tests outlined in this section areconsidered to be one-time qualification tests to establish theadequacy of the manufacturers joint design. Instead of requir-ing performance of these tests, the purchaser may require themanufacturer to certify that pipes and couplings equivalent inmaterial and
29、 design have passed the tests enumerated in thissection. At his own expense, however, the purchaser, bydesignation with his order, shall have the option to require thatassembled pipes and couplings pass the following performancetests without leakage.6.3.1 CouplingsThe couplings, when assembled on pi
30、pe,shall be capable of withstanding simultaneously:6.3.1.1 The minimum crushing load prescribed in Table 1,when tested in accordance with the appropriate section of TestMethods C497, and6.3.1.2 The hydrostatic pressure tests described in 6.3.1.3and 6.3.1.4.TABLE 1 Minimum Crushing LoadPipe ClassD Lo

34、a single pipe with a couplingon each end. The assembly shall be subjected to an internalhydrostatic pressure of 10 psi 70 kPa for 10 min. Any visiblewater leakage shall be considered failure of the test require-ments.6.3.1.4 Maximum Deflected PositionUpon completion ofthe test for pipe in straight a

The deflected assemblyshall be subjected to an internal hydrostat

Dimensions and Tolerances7.1 Couplings and coupling areas of the pipe shall bemachined or otherwise finished to such dimensions as willmeet the joint tightness requirements defi

Sampling9.1 Test all material under this specification after immersionunder water at 73 6 7F 23 6 4C for a minimum of 24 h forthe crushing tests and in a normal air-dried condition inequilibrium with atmospheric humidity for the flexural
41、 tests.9.1.1 Employ sampling procedures providing an averageoutgoing quality limit (AOQL) of 6.5 %, except where specificsampling is required by particular test procedures. AppendixX2 describes a sampling plan which provides an AOQL of6.5 %.9.1.2 The minimum sample size for sampling and accep-tance
42、by attributes or variables shall be in Table 2.9.1.3 Pipes of different sizes or classes but of sequentialmanufacture in a continuous manufacturing process may besampled as being in the same inspection lot.9.2 For crushing tests sample the required number of fulllengths of pipe according to the insp
43、ection lot size. Cut one testspecimen no shorter than 6 in. 150 mm long from theunmachined end of each of the selected pipe lengths.(WarningIn addition to other precautions, when cuttingfiber-cement products minimize the dust that results. Prolongedbreathing or frequent breathing of significant airb
44、orne concen-trations of silica is hazardous. When such dust is generated,effective measures shall be taken to prevent inhalation.)NOTE 5When sampling from continuous production, these tests maybe conducted on dry, equilibrium, or saturated specimens, provided arelationship can be established between
45、 this testing and the specifiedvalues.NOTE 6A manufacturers process with an AOQL of 6.5 % indicatesthat better than 93.5 % of the inspected production exceeds the specifi-cations for marginally accepted product. This type of specificationprovides the protection and confidence of a clearly defined lo
46、werboundary. This would not be true if acceptance were based solely on theaverage value of the measured property. Examples of sampling schemeswhich may be used can be found in documents such as ISO 390. Othersampling schemes may be used which maintain equally rigorous qualitylevels. Inspection by at
47、tributes consists of determining, for every item ofa sample, the presence or absence of a certain qualitative characteristic(attribute) with respect to the applicable specification. It is, in essence, apass-fail inspection which determines the number of items in a sample thatdo or do not conform to
48、the specification. An attribute could be adimensional measurement, or a flexural strength value, or others that aredescribed in these test methods. Inspection by variable consists ofmeasuring a quantitative characteristic for each item in a sample.Conformance with the applicable specification is det
49、ermined from themean values of the measured properties and the statistical variations ofthese values above and below the mean. Appendix X2 details samplingplans to suit all common sampling situations, and specifies the number ofspecimens to be taken from each batch and the acceptance/rejectioncriteria. The specified inspection levels have been selected to suitfiber-cement products, to balance the cost of assessment against confi-dence in results commensurate with this industry.9.3 Each len
