Piping systems for rehabilitation of underground drains, sewers and water supply networks — Part 3: Unplasticized poly (vinyl chloride) (PVC-U) material

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation by means of renovation of underground non-pressure drainage and sewerage networks. It is applicable to unplasticized poly (vinyl chloride) (PVC-U) pipes, fittings and assemblies, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with close-fit pipes.
