Over deze norm
This European Standard specifies requirements for elastomeric materials used in sealing rings for supply pipes and fittings at operating temperatures in general from -5° C up to 50° C and in special cases from -15° C up to 50° C, for the following: a) gaseous fuel (manufactured, natural and liquefied petroleum gas (LPG) in gaseous phase); b) hydrocarbon fluids with aromatic content up to 30% (v/v), including LPG in liquid phase. This Standard is applicable to joint seals for all pipeline materials including iron, steel, copper and plastics. It is not necessarily applicable to materials for joint seals used in pipelines carrying industrial waste fluids. In the case of composite sealing rings, depending on their design and after agreement between the manufacturer and the user, requirements in 4.2.8 and 4.2.9 apply only when the materials used for any elastomeric parts come into contact with gaseous fuel or hydrocarbon fluid. Compression set and stress relaxation requirements for materials of hardness classes 80 and 90 apply only when they constitute that part of the seal which participates directly in the sealing function.
