ASTM D229Standard Test Methods for Rigid Sheet and Plate Materials Used for Electrical Insulation
ASTM D229电绝缘用硬质薄板及板材的标准试验方法
This test method provides useful engineering information for evaluating the mechanical behavior of rigid electrical insulation at elevated temperature. When the proper exposure and test temperatures are chosen, depending on the material and end-use operating temperature, use the test method as one means of indicating relative thermal degradation of rigid
