2. The thickness of overlapping gummed paper cannot exceed 0.1 inch.
3. The angle of the tester and the edge of the sample is 90°±5°.
4. The testing position should be the sharpest parts of the sample.
5. The force should be adjusted to 1.35LBS.
6. Use the ruler to measure the cut length. If the length exceeds 0.5 inch, the edge is the sharp one.
