Elastomeric seals - Material requirements for pipe joint seals used in water and drainage applications - Part 1: Vulcanized rubber

pending
Organization: CEN
Publication Date: 1 July 2016
Status: pending
Page Count: 35
ICS Code (Seals for pipe and hose assemblies): 23.040.80
scope:

This European Standard specifies requirements of materials used for vulcanized rubber seals in:

- cold water (T ≤ 50 °C);

- cold water (T ≤ 50 °C) and intermittently hot water (T ≤ 95 °C);

- cold water (T ≤ 50 °C) and continuously hot water (T ≤ 110 °C).

The different designations of seals specified are defined according to their type, application and requirements (see Table 1).

This European Standard defines requirements for seals, partially defining the properties of the vulcanized rubber material as a performance indicator of the finished seal. 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, pipe system material and pipe joint design. This standard should be used where appropriate with product standards which specify performance requirements for joints.

It is applicable to elastomeric components of composite or non-composite seals.

In case of composite seals for materials of hardness ranges from 55 IRHD to 95 IRHD, the requirements for elongation at break, compression set and stress relaxation apply only when the material is participating in the sealing function, or the long term stability of the seal.

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