Introduction

Organic insulating material plays an important role in the electrical system. They metallic materials, ceramic materials, become electrical technology the main components of materials in the field. In all materials, organic materials are most sensitive to the effects of radiation on materials, different organic materials on radiation Reaction shot effects vary widely. Therefore, the choice of applied radiation environments insulating material requested candidate materials radiation resistance Energy information. Objective GB/T 26168 Part 3 is to provide a hierarchical radiation resistance of insulating materials in the above applications.

This section is "electrically insulating material to determine the effect of ionizing radiation" series, Part 3 standard.

GB/T 26168.1 of introduction, to assess the effects of radiation of many problems. It can be used to know the development of the amount of radiation measured terms, from the use Determination of the amount of radiation exposure and determining the absorbed dose of a specific material and absorbed dose calculation methods.

GB/T 26168.2 describes the steps to maintain the seven different types of radiation in the environment, exposure conditions. It also provides for the above-mentioned radiating strips Member of the control measures, so as to obtain results corresponding to comparative results for the material properties. In addition, it provides for determining Insulation material properties change and the corresponding (end criterion) of certain important irradiation conditions and test procedures.

GB/T 26168.4 introduced in the course of aging assessment procedure.

Electrical insulating materials to determine the effect of ionizing radiation Part 3. Classification System under the radiation environment applications

1 Scope

This section GB/T 26168 specifies the classification system, as an alternative to nuclear reactions and retrieval facilities, reactor fuel processing device Shi, irradiation facilities, ion accelerators and X-ray equipment used in radiation environments insulating material guidance.

Rating system to determine exposure to a variety of three categories of polymeric materials (hard plastic, soft plastic device used in ionizing radiation environment Materials and elastomers) used to provide a set of parameters.

This section forms the basis for the applicability of these materials in a radiation environment quantitative assessment of proposed specifications determining such material and between suppliers and users guide signed purchase agreements.
