Gives requirements for the materials used for moulded seals only of thermoplastic elastomers (TPE) used in joints of: thermoplastic rainwater piping systems; thermoplastic piping systems for non-pressure underground drainage and sewerage (continuous flow not exceeding 45 degree C and intermittent flow not exceeding 95 degree C); thermoplastic piping systems for non-pressure waste water discharge (intermittent flow not exceeding 95 degree C) inside buildings.

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

1. thermoplastic piping systems for non pressure waste water discharge (intermittent flow up to 95 ?C) inside buildings;

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. 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.
