In no case shall the manufac-turers stated inside diameter minus the tolerance in Table 2 beless than the required minimum inside diameter.NOTE 2The manufacturers stated inside d

36、iameter is the nominaldiameter plus or minus the inside diameter tolerances. The minimuminside diameter is the smallest diameter the pipe can be with thesetolerances and is used for the hydraulic design of the pipe.NOTE 3The outside diameters and the corrugation pitch of productsmanufactured to this

37、 specification are not specified; therefore, compatibil-ity between pipe and fittings made to this specification from differentmanufacturers should be verified.6.2.3 Laying LengthThe pipe shall be supplied in anylaying length agreeable to both the owner and the manufac-turer. Laying length shall not

39、flec-tion shall meet the requirements given in Table 2 when testedin accordance with 7.4.NOTE 4The 5 % deflection criterion, which was selected for testingconvenience, is not a limitation with respect to in-use deflection. Theengineer is responsible for establishing the acceptable deflection limit.6
