16、 standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.1

17、5.2 Gaskets shall be tested in accordance with Section 9 onpipe samples complying with applicable industry standards ofmaximum and minimum dimensions. It shall be permissible tomachine pipe samples to attain maximum or minimumdimensions, or both.5.3 The gasket assembly when tested in accordance with

18、Section 9 shall not leak.5.4 The gasket shall accommodate vitreous china plumbingfixtures and flanges conforming to applicable industry stan-dards.6. Dimensions, Mass, and Permissible Variations6.1 Gaskets shall conform to the dimensions and dimen-sional tolerances as agreed upon between the supplie

19、r andpurchaser. All dimensions shall be compatible with the dimen-sions and tolerances of the specific pipe materials and sizes andvitreous china plumbing fixture to which it is designed to join.7. Workmanship, Finish, and Appearance7.1 The surface of preformed gaskets shall be smooth andfree from p

20、itting, cracks, blisters, air marks, or any otherimperfections that may affect product performance in service.7.2 Neither the flash thickness nor the flash extension shallexceed132 in. (1 mm).7.3 Mold release, oil, or grease used in the manufacturingprocess will have a detrimental effect on the abil

21、ity of theadhesive to adhere to the flanged surface of the fixture gasket.Care should be taken not to contaminate the flanged surface ofthe gasket.8. Sampling, Tests, and Retests8.1 Test specimens representative of the gaskets to be usedshall be randomly selected from the manufactured lot fortesting

22、. The manufactured lot shall be a minimum of eighthours old. Tests shall be performed at room temperature.8.2 Where there is a failure in the original test, the entire testshall be rerun with twice the number of samples and any failureshall be cause for rejection.9. Test Method for Assembled Gaskets

23、9.1 Test ApparatusThe apparatus used to conduct this testshall be designed according to the applicable outlet dimensionsof the vitreous china plumbing fixture. See Fig. 1 for example.The test apparatus shall be constructed of clear acrylic witha polished finish.9.2 Significance and UseThis test meth

24、od is useful indetermining the ability of the gasket assembly to provide apermanent seal against water, sewer, sewer gas, and the like invitreous china plumbing fixture to sanitary drain line connec-tions.9.3 HazardsThis is a pressurized hydrostatic test andunder no circumstances shall water be subs

25、tituted with air.Care should be taken in expelling all air prior to pressurizingthe test assembly. Wear eye protection during pressure tests andstrictly adhere to safety precautions at all times.9.4 ProcedureHydrostatic Joint Tightness Test: Wipe thesurface of the test apparatus with denatured alcoh

26、ol. Apply thegasket assembly to the test apparatus. Insert the test apparatusassembly into the test pipe providing an adequate spacebetween the test apparatus and the flange to prohibit compres-sion of the gasket between the test apparatus and flange.Securely tighten the test apparatus to the flange

27、, fill theassembly with water expelling all air, pressurize to 4.3 psi fora period of 15 min. Any leakage shall result in failure. Refer toFig. 2.10. Certification10.1 The gasket manufacturer shall keep appropriate pro-duction and testing records showing compliance to thisspecification, including ce

28、rtified documentation from the PVCcompound producer showing compliance with SpecificationD5926. The manufacturer shall be required to provide saidinformation at the request of the purchaser.11. Product Marking11.1 Each gasket shall be marked with the manufacturersname or trademark, or both.11.2 The

29、type and size of pipe for which the gasket is or themanufacturers product identification shall be marked on orattached to each gasket.11.3 All gaskets shall be marked with the designationASTM A1045 showing compliance to this specification.12.
