GB/T 8411的本部分适用于电绝缘用陶瓷、玻璃陶瓷、玻璃结合云母和玻璃材料。本部分规定了试验方法,目的在于用这些方法测出试样所用材料的典型性能参数。在多数情况下,电绝缘陶瓷部件的尺寸和形状与试样相差很远,因此这些测试所得出的结果仅是实际部件特性的指导性参数。对试样成型和试样处理方法的要求在相关处讨论。
本标准规定了岩心的钻取、处理、保存及岩心分析的准备、测试方法、技术要求及编写报告的格式、本标准适用于在油气藏勘探、开发过程中,对钻井取心及井壁取心岩样的测试分析,其他岩心的分析亦应参照执行、
本标准规定了低压绝缘子瓷件的技术要求、试验、包装和标志的一般要求。本标准适用于直流电压低于1000V的或交流电压低于1000V、频率不超过lOOHz的架空电力线路、电气装置和设备上使用的绝缘子瓷件。本标准不适用于在有破坏瓷及釉的介质(气体或液体)中工作的瓷件。
