36、in Table 3. All dimensions are minimum with anegative tolerance of zero.6.4 Impact StrengthThe impact strength of the pipe and fittings shall not be less than the values given in Table 4 when testedin accordance with 8.9.NOTE 1This test is intended only as a quality control test, not as a simulated
37、service test.6.5 Pipe StiffnessThe pipe stiffness at 5 % deflection shall be not less than the values given in Table 5 when tested inaccordance with 8.10. This requirement does not apply to fittings.NOTE 2The 5 % deflection criterion, which was arbitrarily selected for testing convenience, should no
38、t be considered as a limitation with respect toin-use deflection. The engineer is responsible for establishing the acceptable deflection limit.NOTE 3The strength and load-carrying capabilities of plastic drain and sewer pipe are measured and reported as Pipe Stiffness, which is determinedin accordan
39、ce with Test Method D2412. The term “crush strength” is not applicable to plastic piping because (a) the values obtained can be significantlydifferent, depending on the bedding, loading, or testing technique used; and (b) the term derives from rigid pipe and refers to its ultimate strength atrupture

Retest and Rejection7.1 If the results of any test(s) do not meet the requirements of this specification, the test(s) may be con
42、ducted again inaccordance with an agreement between the purchaser and the seller. There shall be no agreement to lower the minimumrequirement of the specification by such means as omitting tests that are a part of the specification, substituting or modifying a testmethod, or by changing the specific
43、ation limits. In retesting, the product requirements of this specification shall be met and thetest methods designated in the specification shall be followed. If, upon retest, failure occurs, the quantity of product representedby the test(s) does not meet the requirements of this specification.8. Te
