I. Evaluate abrasion resistance of webbing and belting materials.

Textile webbing is often used for safety belts, restraint harnesses, helmet straps, and cargo tie-downs. Over time, adjustment hardware or common use may cause abrasion damage and jeopardize the integrity of the webbing material. The Webbing Abrasion Tester provides a cost effective means to perform abrasion testing. Included weights permit testing of webbing with breaking strengths over 13,500 N to ASTM D6770.

II. Rubbing action simulates field damage in controlled laboratory setting.

A fixed weight is attached to the end of a test specimen before it is subjected to a unidirectional reciprocal rubbing over a steel hexagonal rod, also known as a hex abrasion bar. After the specified number of test cycles, the percent retention of breaking force is calculated. Comparing results to an unabraded specimen provides a measure of how abrasion resistant the material is.

III. Based on established test procedures, instrument offers unique features.
