Elastomeric seals. Requirements for materials for pipe joint seals used in water and drainage applications. Thermoplastic elastomers. | Status: Current

1 Scope This document specifies requirements for materials used for moulded seals made of thermoplastic elastomers (TPEs) for joints in:

1. a) thermoplastic piping systems for non-pressure wastewater discharge (intermittent flow at up to 95 °C) inside buildings;
2. 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);
3. 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.
