16、commodate 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 supplier andpurchaser. All dimensions shall be compatib

17、le 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 pitting, cracks, blisters, air marks, or any othe

18、rimperfections that may affect product performance in service7.2 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 ability of theadhesive to adhere to the flanged surfa

Sampling, Tests, and Retests8.1 Test specimens representative of the gaskets to be usedshall be randomly selected from the manufactured lot fortesting. The manufactured lot shall be a minimum of eigh

20、thours 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 Gaskets9.1 Test ApparatusThe apparatus used to conduct t

21、his 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 method is useful indetermining the ability of the gas

23、 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 alcohol. Apply thegasket assembly to the test apparatus

24、. 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, fill theassembly with water expelling all air, p
