Test method When there is no special provision, the test details should be pre-treated and tested in accordance with the requirements of Chapter 3 of JB/T5970. Appearance The appearance is observed with the eyes and mouth. 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. Electrical strength Tested according to the method in Chapter 13 of JB/T5970,||t t||Inspection rules The recommended factory inspection items are Items 5, 6, and 7 in Table 1 of Articles 4.1, 4.2, and 4.3 of this standard. The determined product temperature index is always valid when the composition or parts and manufacturing process are not changed. Others should be carried out in accordance with the provisions of Chapter 6 of JB/T5969. 2 Marking, packaging, transportation and storage JB/T5657-1991 Should comply with the provisions of JB/T5969 on marking, packaging, transportation and storage. The storage temperature and relative humidity limit values refer to the maximum values caused by climate change, rather than the highest conditions allowed for continuous storage.
