33、allcomply with Table 1, when tested in accordance with 7.6.6.6.1 The wall thickness must be increased to meet the pipestiffness requirement PS46 or PS115 listed in Table 1 whenmaterial with modulus lower than 500,000 psi (3447 MPa) isused.6.7 Gaskets:6.7.1 All gaskets shall meet the requirements of
34、Specifica-tion F477 and be molded into a circular form or extruded to theproper section and then spliced into circular form. Gasketsshall be made of a properly vulcanized high-grade elastomericcompound.6.7.2 The basic polymer shall be natural rubber, syntheticelastomer, or a blend of both.6.7.3 The
35、gasket shall be designed with an adequate com-pressive force so as to effect a positive seal under all combi-nations of joint tolerances. The gasket shall be the only elementdepended upon to make the joint flexible and watertight.6.8 Joint TightnessJoints made with pipe and fittings shallshow no sig
36、n of leakage, when tested in accordance withSpecification D3212. All surfaces of the joint upon which thegasket may bear shall be smooth and free of imperfections,ridges, fractures, or cracks that could adversely affect sealabil-ity.6.9 Acetone ImmersionThe pipe shall not show excessiveflaking or di
37、sintegrate, when tested in accordance with TestMethod D2152.NOTE 5This test is intended only for use as a quality control test andnot for use as a simulated service test.7. Test Methods7.1 Conditioning:7.1.1 Referee TestingWhen conditioning is required forreferee tests, condition the specimens in ac
38、cordance withProcedure A of Practice D618 at 73.4 6 3.6F (23 6 2C) and50 6 5 % relative humidity for not less than 40 h prior to test.Conduct tests under the same conditions of temperature andhumidity, unless otherwise specified.7.1.2 Quality Control TestsFor quality control tests, con-dition specim
39、ens for a minimum of4hinairor1hinwater at73.4 6 3.6F (23 6 2C). Test the specimens at 236 2Cwithout regard to relative humidity.7.2 Test ConditionsConduct tests in the Standard Labora-tory Atmosphere of 73.4 6 3.6F (23 6 2C) and 50 6 5%relative humidity, unless otherwise specified in this specifica-
40、tion. In cases of disagreement, the tolerances shall be 61.8F(61C) and 62 % relative humidity.7.3 SamplingThe selection of the sample or samples ofpipe shall be as agreed upon between the purchaser and seller.In case of no prior agreement, any sample selected by thetesting laboratory shall be deemed
41、 adequate.7.4 FlatteningFlatten three specimens of pipe, each 6 in.(152 mm) in length, between parallel plates in a suitable pressuntil the distance between the plates is 40 % of the outsidediameter of the pipe. The rate of loading shall be uniform andsuch that the compression is completed within 2
42、to 5 min. Thespecimen shall pass if no splitting, cracking, or breaking isobserved under normal light with the unaided eye.7.5 Impact ResistanceDetermine the impact resistance ofthe pipe in accordance with Test Method D2444, using a 30-lb(15-kg) or 20-lb (10-kg) Tup B and flat-plate holder B. Test s
43、ixspecimens. All shall pass. If one fails, test another six speci-mens; 11 passes out of 12 tested shall be acceptable. If two ormore specimens fail, results shall be considered unacceptableand the test shall be recorded as a failure with no furtherretesting allowed.NOTE 6Sections shorter than those
44、 specified in Test Method D2444,but not less than 6 in. (152 mm) in length, may be tested to accommodatethe impact-testing machine since this will be a more severe impact-resistance test.7.6 Pipe StiffnessDetermine the pipe stiffness at 5 %deflection datum in accordance with Test Method D2412. Testt
45、hree specimens, each 6 in. (152 mm) in length, and determinethe average pipe stiffness at 5 % deflection in accordance withTest Method D2412. The pipe stiffness shall equal or exceedthe minimum value listed in Table 1.NOTE 7The 5 % deflection criterion, which was arbitrarily selectedfor testing conv
46、enience, should not be considered as a limitation withrespect to in-use deflection. The engineer is responsible for establishingthe acceptable deflection limit.7.7 Acetone ImmersionThis test shall be conducted inaccordance with Test Method D2152. This procedure is usedfor determining the degree of f
47、usion of extruded PVC plasticpipe as indicated by reaction to immersion in anhydrousacetone. It is applicable only for distinguishing betweenunfused and properly fused PVC.8. Retest and Rejection8.1 If the results of any test(s) do not meet the requirementsof this specification, the test(s) may be c
48、onducted again inaccordance with an agreement between the purchaser and theseller. There shall be no agreement to lower the minimumrequirement of the specification by such means as omittingtests that are a part of the specification, substituting ormodifying a test method, or by changing the specific
49、ationlimits. In retesting, the product requirements of this specifica-tion shall be met, and the test methods designated in thespecification shall be followed. If, upon retest, failure occurs,the quantity of product represented by the test(s) does not meetthe requirements of this specification.F679 1539.
