GB/T 11026.6-2010 "Electrical insulating materials - heat resistance - Part 6: aging oven - Multi-chamber oven" specifies the model, size, technical requirements, test methods, etc. of the multi-chamber aging oven used for the heat resistance test of electrical insulating materials. The standard is applicable to different types of electrical insulating materials, and its heat resistance is evaluated through the aging test of the multi-chamber oven. The standard ensures the Temperature control accuracy and Stability of the aging oven during the experimental process, providing a reliable basis for the performance test of insulating materials, and is widely used in materials testing in electric power, electronics and other fields.
