Elastomeric seals. Material requirements for pipe joint seals used in water and drainage applications. Thermoplastic elastomers | Status: Current, Under review

1 Scope This standard specifies requirements for materials used for moulded seals only of thermoplastic elastomers (TPE) used in joints of:

1. 1) thermoplastic piping systems for non pressure waste water discharge (intermittent flow up to 95 °C) inside buildings;
2. 2) thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow up to 45 °C and intermittent flow up to 95 °C);
3. 3) thermoplastic rainwater piping systems.

General requirements for finished joint seals are also given; any additional requirements called for by the 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.
