What is BS EN 291 – static rubber seals for domestic gas about?
BS EN 291 is a European Standard that specifies requirements and test methods for homogeneous rubbers for static seals used in domestic gas appliances of all categories, and in auxiliary equipment mounted or intended to be mounted on such appliances which are in contact with combustible gases up to 200 mbar (not including LPG in liquid phase).
BS EN 291 does not specify the geometrical characteristics of the seals. The normal range of envisaged operating temperatures covered by BS EN 291 is 0 °C to 60 °C. Temperatures outside this range can be proposed by the manufacturer with limits between – 20 °C and + 150 °C.
Note: BS EN 291 defines only the quality of materials to be used for the manufacture of seals. It may be necessary to carry out supplementary tests on the seals themselves.
