scope:

This European Standard specifies the requirements for pipes and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems with structured-wall pipes intended to be used for soil and waste discharge (low and high temperature) inside buildings (marked with "B"). It also specifies the test parameters for the test methods referred to in this standard. It covers pipes with an external and internal smooth layer which are connected with foamed PVC-U or by radial legs in solid PVC-U. The fully foamed PVC-U pipes and spiraly-formed PVC-U pipes are not covered by this standard.
