标准范围

本文件规定了硫化橡胶密封件所用材料的要求:A）？冷饮用水供应（高达50？°C）；b）？排水、污水和雨水系统（连续流量高达45？°C，间歇流量高达95？°C）。密封件的不同名称是根据其类型、应用和要求定义的（见表？5）。还给出了成品接头密封的一般要求；考虑到管接头的性能是密封材料特性、密封几何形状和管接头设计的函数，特定应用要求的任何附加要求在相关产品标准中规定。在适当的情况下，本文件旨在与规定接头性能要求的产品标准一起使用。本文件适用于所有管道材料的接头密封，包括铁、钢、粘土、纤维水泥、混凝土、钢筋混凝土、塑料和玻璃钢。它适用于复合材料或非复合材料密封件的弹性体部件。对于硬度范围为76？IRHD-M到95？IRHD-M，断裂伸长率、压缩永久变形和应力松弛的要求仅在材料参与密封功能或密封的长期稳定性时适用。将封闭空隙作为其设计的一部分制成的接头密封包含在本文件的范围内。

This document specifies requirements for materials used in vulcanized rubber seals for the following:

a)       cold drinking-water supplies (up to 50 °C);

b)       drainage, sewerage, and rainwater systems (continuous flow up to 45 °C and intermittent flow up to 95 °C).

The different designations of seals specified are defined according to their type, application, and requirements (see Table 5).

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 document is intended to be used, where appropriate, with product standards which specify performance requirements for joints.

This document 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 composite seals for materials of hardness ranges from 76 IRHD-M to 95 IRHD-M, the requirements for elongation at break, compression set, and stress relaxation apply only when the material is participating in the sealing function 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 this document.
