Elastomeric seals - Requirements for materials for pipe joint seals used in water and drainage applications - Thermoplastic elastomersstandard by International Organization for Standardization, 09/30/2022
standard by International Organization for Standardization, 09/30/2022
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.
