EN 549:2019+A1:2023

Rubber materials for seals and diaphragms for gas appliances and gas equipment

This document specifies requirements and associated test methods for rubber materials used in gas installations, gas equipment and gas appliances in contact with 1st, 2nd and 3rd family combustible gases as 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 applicable to materials from which homogeneous seals and homogeneous or reinforced diaphragms are manufactured.
Since the dimensions and shape of the components differ from those of standard test pieces taken from sheet material as used for type testing of the rubber materials according to this document, tolerances have been made in the requirements specified by Annex A for the components with respect to those specified 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. above 200 hPa (200 mbar) nominal pressure or at temperatures below 0 °C with 3rd family gases.

Gumeni materiali za tesnila in membrane v plinskih aparatih in plinskih napravah - Dopolnilo A1

Ta dokument določa zahteve in z njimi povezane preskusne metode za gumene materiale, ki se uporabljajo v plinskih napeljavah, plinskih napravah in plinskih aparatih v stiku z vnetljivimi plini iz 1., 2. in 3. družine, razvrščenimi v skladu s standardom EN 437:2018, pri čemer zajema tudi utekočinjeni naftni plin (LPG), biometan in utekočinjeni naftni plin biološkega izvora enake kakovosti. Vzpostavlja tudi razvrstitev glede na temperaturno območje delovanja in trdoto. Ta dokument se uporablja za materiale, iz katerih so izdelana homogena tesnila in homogene ali ojačane membrane.
Ker se mere in oblika komponent razlikujejo od standardnih preskušancev iz plastnega materiala, ki se uporabljajo za tipsko preskušanje gumenih materialov v skladu s tem dokumentom, so bila v zahtevah, določenih v dodatku A, določena dovoljena odstopanja za komponente glede na tiste, ki veljajo za standardne preskušance.
Ta dokument zajema temperaturno območje delovanja od –40 °C do +150 °C.
Za načine uporabe, pri katerih je lahko prisotna kondenzacija, se ta dokument ne uporablja za silikonsko gumo, npr. pri nazivnem tlaku nad 200 hPa (200 mbar) ali temperaturi pod 0 °C s plini iz 3. družine.
