Taber Webbing Abrasion Tester
Used to evaluate abrasion resistance properties of seat belts and other webbing products (e.g. safety straps, tiedowns, harnesses, helmet straps, etc.), the Taber® Webbing Abrasion Tester has the capacity to test materials with a breaking strength over 13,500 N per ASTM D6770, MIL-W-23223B, US Department of Transportation FMCSA Part 571.209 or other internationally recognized test standards. Materials include nylon, polyester, leather, polymers, and other flexible sheet materials.
Test specimens are weighted, then subjected to a unidirection reciprocal rubbing action as it travels back and forth over a hexagonal (hex) abrasion bar. A specimen clamp bar secures the specimen to the instrument, while a specimen roller ensures an angle of 85° (±2°) is maintained between the specimen and hex bar. After the specified number of test cycles, the percent retention of breaking force is calculated. The comparison of results to an unabraded sample provides a measure of the material's abrasion resistance.
The test specimen passes over two of the six abrading edges of the 12" hex abrasion bar during each test. To maintain abrasion rates, the hex abrasion bar should be rotated so that two new edges are in place for the next test. After three tests, a new section of the hex bar should be utilized or the bar should be discarded and replaced. Depending on specimen width, three specimens can be evaluated simultaneously.
Other features of the Taber Webbing Abrasion Tester include a slotted roller channel allowing stroke length adjustments up to 318mm (12.5 inch); five preset speeds including 15, 30, 37, 45, and 60 cycles per minute; hinged, transparent safety cover; and a standard weight set of 2, 4 & 5.2 lbs. (an optional weight set of 3 & 5 lbs. is also available).
