本指导性技术文件规定户外用聚合物绝缘材料的重要材料性能,并在材料适用的情况下列出包含有最低要求的标准测试方法。如果没有适用的标准测试方法,则参考本指导性技术文件中总结的测试方法。 本指导性技术文件适用于系统电压高于1000V 交流电压的户外高压用聚合物绝缘材料,也包括外壳是设备整体部件的应用场合,例如在避雷器里和电缆终端。本指导性技术文件范围仅限于这些材料。绝缘子的使用性能取决于若干因素,如材料的类型、设计、环境条件等。因此,选择材料时,满足下列要求是必要的,但是这不能保证材料用于户外绝缘时性能达标。

1.1 This test method covers the procedure for determining the volume resistivity, measured longitudinally, of extruded crosslinked and thermoplastic semiconducting, conductor and insulation shields for wire and cable. 1.2 In common practice the conductor shield is often referred to as the strand shield. 1.3 Technically, this test method is the measurement of a resistance between two electrodes on a single surface and modifying that value using dimensions of the specimen geometry to calculate a resistivity. However, the geometry of the specimen is such as to support the assumption of a current path primarily throughout the volume of the material between the electrodes, thus justifying the use of the term ???longitudinal volume resistivity.??? (See 3.1.2.1) 1.4 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 7.1.
