1 Scope
This document specifies requirements for materials used for moulded seals made of
thermoplastic elastomers (TPEs) for joints in:
-
a) thermoplastic piping systems for non-pressure wastewater discharge (intermittent flow at up to 95 °C) inside buildings;
-
b) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow at up to 45 °C and intermittent flow at up to 95 °C);
-
c) thermoplastic rainwater piping systems.
General requirements for finished joint seals are also given; any additional requirements
for a particular application are specified in the relevant product standards taking
into account that the performance of pipe joints is a function of the seal material
properties, seal geometry and pipe joint design.
