scope:

This standard specifies requirements for elastomeric materials used in seals for supply pipes and fittings , ancillaries and valves 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: General applications 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. Special applications: Materials suitable for carrying gaseous fuels containing gas condensates and hydrocarbon fluids of unrestricted aromatic content. This standard is applicable to joint seals for all pipeline materials including iron, steel, copper and plastics.
