IEC TR 61244-4:20 19（E）为用于暴露于电离辐射的设备类型的电绝缘材料（EIM）和电绝缘系统（EIS）的评估/验证提供了一般指南。除了传感器、致动器/电机以及插头和端子之外，电缆是这些EIM和EIS的众所周知的典型应用。其类型范围涵盖低压电力电缆、控制电缆和仪表电缆。由于其相对简单的设计，电缆是研究EIM和EIS降解过程的理想设备类型。但是这些研究的结果可以很容易地转移到列举的设备类型上。尽管如此，本文件提供了一份关于鉴定/验证程序的最新报告，用于模拟不同强度下温度和辐射的同时影响，而不是给出对特定测试方法有效的详细测试程序。注1？将本文件用于特定产品时，可能需要规定其他产品相关程序。注2？本文档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、以前的经验以及边界条件。

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.
