BS EN 681-3:2000

This standard BS EN 681-3:2000 Elastomeric seals. Materials requirements for pipe joint seals used in water and drainage applications is classified in these ICS categories:

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

This standard specifies requirements for materials used in vulcanized rubber seals of cellular materials for non-pressurized drainage, sewerage and rainwater systems and non- pressure non-potable water supply (continuous flow up to 45 °C).

General requirements for the 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.

This standard is applicable to joint seals for pipeline materials of vitrified clay, fibre cement, concrete, reinforced concrete, plastics and glass-reinforced plastics.

Joint seals made with an enclosed void as part of their design are included in the scope of this European Standard.
