The placement position is as follows:
For each different product structure such as plane, sealing edge, groove, etc., 3 cigarettes need to be placed.
Test requirements:
The scorch length of the sample burned by the cigarette does not exceed 2in.
The scorch length of the sample burned by the cigarette does not exceed 2in.
If the product is tested separately to 16 CFR 1632, a total of 6 samples need to be tested.
