5.2 Dimensions
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 steel ruler accurate to 1cm. 5.2.3 Thickness
The thickness is measured according to the method in Chapter 4 of JB/T5970. 5.3 Electrolytic corrosion
The sample is treated at 23±2℃ and relative humidity of 91%~95% for 24 hours 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 is determined according to the method in Chapter 8 of JB/T5970. The aging temperature is recommended as follows;
Type 1 adhesive tape: 170, 190, 210℃;
