标准范围
This International Standard specifies requirements for materials used in vulcanized rubber seals forthe following:a) cold drinking-water supplies (up to 50 °C);b) drainage, sewerage, and rainwater systems (continuous flow up to 45 °C and intermittent flowup to 95 °C).The different designations of seals specified are defined according to their type, application, andrequirements (see Table 3).General requirements for finished joint seals are also given; any additional requirements called for bythe particular application are specified in the relevant product standards, taking into account that theperformance of pipe joints is a function of the seal material properties, seal geometry, and pipe jointdesign. This International Standard is intended to be used, where appropriate, with product standardswhich specify performance requirements for joints.This International Standard is applicable to joint seals for all pipeline materials, including iron, steel,clay, fibre cement, concrete, reinforced concrete, plastics, and glass-reinforced plastics.It is applicable to elastomeric components of composite or non-composite seals. In the case of compositeseals for materials of hardness ranges from 76 IRHD to 95 IRHD, the requirements for elongation atbreak, compression set, and stress relaxation apply only when the material is participating in the sealingfunction or in 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 thisInternational Standard.
