Inspection, marking, packaging, transportation and storage 6
6.1 Using the same raw materials and process, the continuous production of mica tapes of no more than 1000kg is a batch, and each batch of mica tapes should have the same performance. Products should be inspected before delivery. The inspection items are 4.1, 4.2, 4.3 and 4.4 of this part. 6.2 The inspection before delivery should be carried out by sampling in batches, and 1 disk should be taken from each tube (bag) of no less than 5% of the total packaging tubes (bags) in a batch (if the number is less than 3 tubes (bags), at least 3 disks can be taken from the tubes (bags) of the same batch for inspection. 6.3 The storage period of mica tape is 6 months at room temperature from the date of delivery. 6.4 Others should comply with the provisions of GB/T50202002.
