Editing Motorcycle boot (section)

====Impact cut====
Next, the boots are tested to see how they’d hold up if they came up against a sharp object. For this, a blade attached to a mounting block is dropped onto a sample of the boot; apparatus measures how far the blade goes through the boot. The tests use the same areas as the abrasion test (see above) and the blade is dropped at different speeds to test each area. When testing area A, the knife will be dropped at two metres per second (m/s). For a Level 1 and a Level 2 rating, the knife can't protrude through the material by more than 25mm. Area B is tested by dropping the blade at 2.8m/s. For Level 1 approval, the blade can't go through the sample by more than 25mm. To pass Level 2, the maximum it can go through is 15mm.
