The TVAB abrasion testing equipment is so precise that it has set the standards for ISO 6722-1. It has been designed to test the durability of cable insulation under extreme conditions, and measures very specific durability variables. 

This device does abrade the surface of the insulation in both directions along the longitudinal axis of the test sample. A counter will record the numbers of cycles to failure. When the needle abrades through the insulation and makes contact with the conductor, the machine will stop operating.
