4 sample requirements and sample preparation
4.1 Sampling
For rolled back sheet samples, the outermost two layers of film should be removed from the film roll at the time of sampling, and then, according to outdoor tests and sex
The test can be sampled; for the sheet back sample, it is randomly sampled.
4.2 Pretreatment
The backsheet sample should be placed at a temperature of (23 ± 2) ° C and a relative humidity (50 ± 5)% for at least 24 h.
