This standard applies to the assessment of the heat aging performance of flexible sheets for electrical insulation. It refers to the test method including the power frequency electric strength of solid insulating materials and the guidelines for determining the heat resistance aging of electrical insulating materials. The preparation of the specimen involves taking 27 copper tubes, each at least 310mm long, polishing to an outer diameter of 15 mm soil 0.2 mm, wiping and dividing them into three groups for different test temperature points.
