适用范围：This standard specifies requirements for materials used in factory cast polyurethane sealing elements used in joints for drainage, sewerage and rainwater systems and non-potable water supply for continuous flow up to 45 ℃. General requirements for finished joint seals are also given; any additional requirements called for by the particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design. This standard is applicable to joint seals for all pipeline materials, including iron, steel, clay, fibre cement, concrete, plastics and glass-reinforced plastics.
