1 Scope
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.
