标准范围

本文件规定了在一般工作温度下，供应管道和配件、辅助设备和阀门密封件中使用的弹性体材料的要求？5°C至50°C，特殊情况下从？15°C至50°C，用于以下情况:a)一般应用(参见表4，G型系列):-气体燃料[气相的人造天然气和液化石油气(LPG)]，-芳烃含量高达30%(按体积计)的烃流体，包括液相中的LPG；b)特殊应用（参见表4，H型）:-适用于携带含有气体冷凝物和芳烃含量不受限制的烃流体的气体燃料的材料。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、密封几何形状和管道连接的函数，特定应用要求的任何附加要求在相关产品标准中规定国际设计。本文件适用于规定接头性能要求的产品标准。本文件适用于所有管道材料的接头密封，包括铁、钢、铜和塑料。在复合密封圈的情况下，5.2.8和5.2.9中的要求仅在用于任何弹性体部件的材料与气体燃料或碳氢化合物流体接触时适用。硬度等级为80和90的材料的断裂伸长率、拉伸强度、压缩永久变形和应力松弛要求仅当它们构成密封件中直接参与密封功能或直接有助于长期稳定性的部分时才适用。本文件不适用于以下情况:-由多孔材料制成的密封件；-具有封闭空隙作为其设计的一部分的密封件；-需要耐火焰或耐热应力的密封件；-密封件，其包含连接预硫化型材端部的接头。

This document specifies requirements for elastomeric materials used in seals for supply pipes and fittings, ancillaries and valves at operating temperatures in general from?5 °C up to 50 °C and in special cases from?15 °C up to 50 °C, for the following:a) general applications (see Table 4, type G series):

• — gaseous fuel [manufactured, natural and liquefied petroleum gas (LPG) in the gaseous phase],
• — hydrocarbon fluids with an aromatic content up to 30 % (by volume), including LPG in the liquid phase;

b) special applications (see Table 4, type H):

• — materials suitable for carrying gaseous fuels containing gas condensates and hydrocarbon fluids of unrestricted aromatic content.

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 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, copper and plastics.In the case of composite sealing rings, the requirements in 5.2.8 and 5.2.9 apply only when the materials used for any elastomeric parts come into contact with gaseous fuel or hydrocarbon fluid.Elongation at break, tensile strength, compression set and stress relaxation requirements for materials of hardness classes 80 and 90 apply only when they constitute that part of the seal which participates directly in the sealing function or contributes directly to long-term stability.This document is not applicable to the following:— seals made from cellular materials;— seals with enclosed voids as part of their design;— seals required to be resistant to flame or to thermal stress;— seals which contain splices joining pre-vulcanized profile ends.
