5.2 Size
5.2.1 Width
The width is measured with a steel ruler with a graduation value of 0.5mm. 5.2.2 Length
The length is measured with a meter or a saw ruler accurate to 1cm. 5.2.3 Thickness
The thickness is measured according to the method in Chapter 4 of JB/T5970. Electrolytic corrosion
Thickness>600 per meter||tt ||The sample was treated at 23±2℃ and relative humidity of 91%～95% for 24h and then tested according to the method in Chapter 5 of JB/T5970. 5.4
Long-term heat resistance
The temperature index of the material was determined according to the method in Chapter 8 of JB/T5970. The recommended aging temperatures are: 150℃, 160℃ and 180℃. Failure standard 1-electrical strength: 35MV/m, tensile strength and elongation at break were calculated for the original thickness
Tested according to the method in Chapter 10 of JB/T5970,
Adhesion to steel plate and adhesion to substrate were tested according to the method in Chapter 11 of JB/T5970.
