BS EN 681-2:2000

This standard BS EN 681-2:2000 Elastomeric seals. Material requirements for pipe joint seals used in water and drainage applications is classified in these ICS categories:

• 23.040.80 Seals for pipe and hose assemblies
• 23.040.05 Pipelines and its parts for external sewage systems

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.
