Scope of this Standard

This standard specifies the requirements for unplasticized poly(vinyl chloride) (PVC U) pipes, fittings and piping systems intended for use for non-pressure underground drainage and sewerage for the conveyance of soil and waste discharge of domestic and industrial origin, as well as surface water. It covers buried pipework but does not apply to piping systems buried within the building structure. In the case of industrial discharge, the chemical and temperature resistance have to be taken into account, but this will have to be done separately. This International Standard is applicable to PVC U pipes with or without an integral socket. Fittings may be manufactured (i.e. produced on a large scale) by injection-moulding or be fabricated (i.e. produced on a small scale) from pipes and/or mouldings. This International Standard also specifies the test parameters for the test methods referred to herein. It does not cover requirements for the K value of the raw material.
