Homopolymer PVCcompounds must meet or exceed the requirements of the abovelisted minimum cell classification number.5.2 Re

19、work MaterialClean rework material generatedfrom the manufacturers own pipe or fittings production maybe used by the same manufacturer provided pipe or fittingsproduced meet all the requirements of this specification.5.3 GasketsElastomeric gaskets shall comply with therequirements described in Speci

20、fication F 477.5.4 LubricantThe lubricant used for assembly shall besuitable for use with PVC pipe and elastomeric seals for thisapplication and have no detrimental effect on the gasket or onthe pipe.6. Joining Systems6.1 Gasketed JointThe integral bell gasketed joint, cou-pling, or fitting joints s

21、hall be designed so that when as-sembled, the gasket (which is attached to either the bell or thespigot) will be compressed radially on the pipe spigot or in thebell to form a water-tight seal. The joints shall be designed tocomply with and show no sign of leakage when tested inaccordance with 7.7 w
