Introduction

In the field of electrical insulation materials, organic and polymeric materials account for a large proportion. These materials are sensitive to the effects of radiation and materials Different types, the degree of response is also very different. It is therefore important to assess the extent to which the insulating material ages during use. Recommended in this section The aging evaluation procedure for insulation materials during operation. There are several ways to assess the lifetime of a base polymer exposed to an irradiated environment, and development in this area is based on aging over the past few decades. Understanding of factors affecting degradation. In nuclear power plants, identification procedures are often used to select materials, including polymer-based materials. Previous identification procedures It was developed in the absence of sufficient knowledge of the aging mechanism, so most of the methods discussed in this section cite the previous identification procedures. limitation. This part is the fourth part of GB/T 26168, which is the evaluation procedure for aging during operation. Electrical insulation determines the effects of ionizing radiation Part 4. Assessment procedures for aging during operation

1 Scope

This part of GB/T 26168 specifies the operational life assessment method for components consisting of polymeric materials used in radiation environments, such as Cable insulation and sheathing, elastomeric sealing sleeves, polymer coatings and rubber sleeves. This section applies to methods for assessing aging during operation, including ageing assessment procedures based on condition monitoring, and sample retention in harsh environments. The use of the sample and the preparation of the actual aged sample.
