The standard specifies the use of the Cambridge type impact abrasion tester. This test involves dropping the clothing material onto an abrasive belt moving at 28 km/hr and measuring the time for a hole to form. This method is often criticized for not being similar to that seen on the road however Dr Woods used both accident damage and that seen in manikins thrown from a moving vehicle to ensure that the test replicated the real world damage as close as possible.This test has been used to show that there is a relationship between fabric thickness and time to hole for protective denim products.
