2、 oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers material and performancerequir
3、ements for plasticized PVC compression gaskets used inthe connection of residential and commercial vitreous chinaplumbing fixtures to 2, 3 and 4-in. sanitary drain lines. Thesetype gaskets are inserted into and compress against the insidediameter of the sewer pipe, closet or urinal flange whileattac

16、ous 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 compatible with the dim
17、en-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 otherimperfections t
18、hat 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 surface of the fixtur
19、e 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. The manufactured lot shall be a minimum of eighthours old. Test
20、s 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 this testshall be
21、 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 gasket assembly to
22、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 substituted with air.Care should be taken in expelling all air prior t
23、o 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. Insert the tes
24、t 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, pressurize to 4.3
25、 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 this speci-fication, including certified documentation from the PVCcompound producer showing comp
26、liance 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 type and size of pipe for which the gasket is or themanufacturer
27、s 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.
