本指南的目的是对电绝缘材料必须运行的伽马辐射、中子通量和温度的环境条件进行分类。这些环境分类适用于将暴露于核辐射的非军事设备和装置的适当电气绝缘类型的规范和选择。

The purpose of this Guide is to classify the environmental conditions of gamma radiation, neutron flux, and temperature in which electrical insulating materials must operate. These environmental classifications are applicable to the specification and selection of the appropriate types of electrical insulation for nonmilitary equipment and devices that will be exposed to nuclear radiation.
