ISO 23711:2003 PDF

ISO 23711:2003 specifies requirements for materials used for moulded seals made of thermoplastic elastomers (TPEs) for joints in:

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