The JB/T 1544-2015 standard specifies a test method for electrical insulating impregnating materials and lacquered cloths under rapid heat aging conditions, using the hot accent oblique method. This method is used to evaluate the durability and Stability of electrical insulating materials in a high temperature environment. During the test, the sample is aged at a set temperature and Humidity, simulating its aging process in actual use, thus providing reliable data on material performance. The standard applies to the quality control and performance evaluation of electrical insulating materials, ensuring their long-term Reliability in the use environment.
