Full Description

This document specifies requirements and associated test methods for rubber materials used in gasinstallations, gas equipment and gas appliances in contact with 1st, 2nd and 3rd family combustible gasesas classified in EN 437:2018, additionally LPG, bio methane and bio LPG, in the same quality, are covered.It also establishes a classification based on temperature range and hardness. This document is applicableto materials from which homogeneous seals and homogeneous or reinforced diaphragms aremanufactured.

Since the dimensions and shape of the components differ from those of standard test pieces taken fromsheet material as used for type testing of the rubber materials according to this document, toleranceshave been made in the requirements specified by Annex A for the components with respect to thosespecified for standard test pieces.

The range of operating temperatures covered by this document is -40 C to +150 C.

For applications with potential condensation, this document is not applicable for silicon rubber, e.g. above200 hPa (200 mbar) nominal pressure or at temperatures below 0 C with 3rd family gases.
