52 Sample preparation
Put the sample in the environment specified in 5.1 for more than 2h, remove 3~~5 turns of the outer tape, and The length direction of the tape is to be tested in accordance with the test method standards. 5.3 Specification Inspection
53.1 Width
Cut a test piece of about 300mm long from the tape: use a vernier caliper with a minimum graduation value of no more than 0.1mm to measure three approximately equal points along the length direction, and calculate the arithmetic mean of the three values. 532 Length
After unwinding the tape, place it on a plane with a length greater than 1m without applying any external force, and use a vernier caliper with a graduation value of no more than 1mm to measure the length of the tape. Steel tape measurement
