42、abrading rod with the edged surface facing down (perpendicular with the test specimen). (2) Remove approximately 1 inch (25.4 mm) of insulation from the end of the specimen and connect the circuit detection clip to the exposed conductor. (3) Apply the appropriate weights to the fixture. (4) Place th

43、e abrading rod on the specimen, ensuring the rod is level and perpendicular to the specimen surface. (5) Zero the counter on the abrasion tester. (6) Turn the tester on. The rod will begin to oscillate over the surface of the specimen with an approximate 1 inch (25.4 mm) stroke. (7) The test will co

44、ntinue until the tester detects continuity between the abrading rod and the conductor. (8) Record the number of cycles to failure. (9) Repeat the procedure a minimum of 10 times (100 times preferred) to generate a statistically significant sample. (10) Average the results. Provided by IHSNot for Res
