标准摘要
[中文适用范围]： 本文件是IEC 61244的一部分，为评估和验证拟用于暴露于电离辐射设备类型的电气绝缘材料（EIM）和电气绝缘系统（EIS）提供了总体指导。除了传感器、执行器/电机以及插头和端子外，电缆是这些EIM和EIS的典型应用。其类型谱系包括低压电力电缆、控制电缆和仪表电缆。由于其设计相对简单，电缆是研究EIM和EIS降解过程的理想设备类型。然而，这些研究的结果可以轻松转移到列举的设备类型。尽管如此，本文件提供了关于模拟温度和辐射在不同强度下同时效应的资格/验证程序的最新技术报告，而不是提供适用于特定测试方法的详细测试计划。注1：将本文件用于特定产品可能需要指定额外的产品相关程序。注2：本文件中描述的一些程序是新兴技术。因此，可以额外考虑指定的先决条件、先前的经验以及边界条件。 [外文原描述]： IEC TR 61244-4:2019(E) provides general guidance for the evaluation/verification of electrical insulation materials (EIM) and electrical insulation systems (EIS) intended to be used in types of equipment exposed to ionizing radiation. Beside sensors, actuators/motors as well as plugs and terminals, cables are a well-known typical application of those EIM and EIS. Their type spectrum covers low voltage power cables, control cables and instrumentation cables. Because of their comparable simple design, cables are the ideal type of equipment to study EIM and EIS degradation processes. But the results of these studies can be easily transferred to the enumerated types of equipment. Nonetheless, this document provides a state-of-the art report on qualification/verification procedures used to simulate simultaneous effects of temperature and radiation at varying intensities rather than give detailed test programmes valid for specific test methods. NOTE 1 Use of this document with specific products can require specification of additional product related procedures. NOTE 2 Some of the procedures described in this document are emerging technologies. Therefore, specified prerequisites, former experiences as well as boundary conditions can be additionally taken into account.
