適用范圍：This Standard specifies requirements for synthetic elastomeric materials used in vulcanized seals with the exception of natural rubber and polyisoprene compounds for—(a) cold potable water supply (up to 50°C);(b) hot potable and non-potable water supply (up to 110°C);(c) drainage, sewerage and rainwater systems (continuous flow up to 45°C andintermittent flow up to 95°C);The different designations of seals specified are defined according to their type, application and requirements (see Table 4.1).General requirements for finished joint seals are also given. Any additional requirementscalled 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 should be used, where appropriate, with product Standards that specify performance requirements for joints.This Standard is applicable to joint seals for all pipeline materials, including iron, steel, clay, fibre cement, concrete, reinforced concrete, plastics and glass-reinforced plastics; and elastomeric components of composite or non-composite seals.In the case of composite seals for materials of hardness ranges from 76 IRHD to 96 IRHD, the requirements for elongation at break, compression set and stress relaxation apply only when the material is participating in the sealing function, or the long-term stability of the seal.Joint seals made with an enclosed void as part of their design are included in the scope of this Standard.Means for demonstrating compliance with this Standard are given in Appendix A.
