26、ber 2005.This standard is Part of a System Standard for plastics piping systems of a particular material for a specifiedapplication. There are a number of such System Standards.System Standards are based on the results of the work undertaken in ISO/TC 138 “Plastics pipes, fittings andvalves for the

27、transport of fluids“, which is a Technical Committee of the International Organisation forStandardization (ISO).They are supported by separate standards on test methods to which references are made throughout the SystemStandard.The System Standards are consistent with general standards on functional
