标准摘要
[中文适用范围]： 涵盖多种电工绝缘材料，为材料选择、寿命预测及安全评估提供了技术依据。该指南强调科学性与一致性，引导用户在实际测试中遵循标准化的操作步骤，从而准确反映材料在长期热作用下的可靠性表现。所有方法均基于广泛的技术验证，旨在促进全球范围内绝缘材料测试结果的相互认可与互用。 [外文原描述]： Gives principles of test procedures to evaluate the thermal endurance of electrical insulating materials and simple combinations of such materials; describes the conditions to be observed during the various tests and shows the basic analysis methods to derive the temperature index, the relative temperature index and the halving interval from the test results. Attention is given to test data which do not completely satisfy the requirements of linearity and dispersion of the thermal endurance relationship.
