标准范围
ISO 9631:2003规定了用于热饮用水和非饮用水供应（最高110°C）的硫化橡胶密封件的材料要求。根据密封类型、密封应用和特定密封的要求，规定了不同的密封名称。还给出了成品接头密封件的一般要求。考虑到管道接头的性能是密封材料性能、密封几何形状和管道接头设计的函数，相关产品标准中规定了特定应用要求的任何附加要求。本国际标准适用于规定接头性能要求的产品标准。本国际标准适用于所有管道材料的接缝密封，包括铁、钢、粘土、纤维水泥、混凝土、钢筋混凝土、塑料和玻璃钢。适用于复合密封和非复合密封的弹性元件。对于由硬度范围为76 IRHD至95 IRHD的材料制成的复合密封件，只有当材料参与密封功能或有助于密封件的长期稳定性时，才适用断裂伸长率、压缩永久变形和应力松弛的要求。本国际标准不包括由多孔橡胶材料制成或带有封闭空隙（作为其设计的一部分）的接合环。
ISO 9631:2003 specifies requirements for materials used in vulcanized-rubber seals for hot potable and non-potable water supply (up to 110 °C).The different seal designations specified are defined according to seal type, seal application and the requirements for a particular seal.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 International Standard is intended to be used where appropriate with product standards which specify performance requirements for joints.This International Standard is applicable to joint seals for use with 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 and non-composite seals. In the case of composite seals made from materials with hardnesses ranging from 76 IRHD to 95 IRHD, the requirements for elongation at break, compression set and stress relaxation apply only when the material participates in the sealing function or contributes to the long-term stability of the seal.Joint rings made from cellular rubber materials or with enclosed voids as part of their design are not covered by this International Standard.
