电绝缘材料.确定电离辐射的影响.第5部分:在使用过程中的老化评定方法

[中文适用范围]： 涵盖可应用于基于聚合物材料的组件（例如，电缆绝缘和护套、弹性密封件、聚合物涂层、防护罩）的老化评估方法，这些组件在暴露于辐射的环境中使用 [外文原描述]： Covers ageing assessment methods which can be applied to components based on polymeric materials (for example, cable insulation and jackets, elastomeric seals, polymeric coatings, gaiters) which are used in environments where they are exposed to radiation. The object of this part of IEC 60544 is to provide guidelines on the assessment of ageing in service. The approaches discussed cover ageing assessment programmes based on condition monitoring (CM), the use of equipment deposits in severe environments and sampling of real-time aged components.
