Auto Cable Sandpaper Abrasion Test Apparatus
1. Introduction
The auto cable sandpaper abrasion test apparatus meets the requirements of ISO6722-1 clause 5.12.4.1 figure 6, GB/T25085, QC/T730, JASO D608, JASO D611, SAE J1127, SAE J1128 and JIS C3406 standard. It’s applied for verify that the resistance of the cable insulation to sandpaper abrasion.
Measure the “resistance to sandpaper abrasion” using 150J garnet sandpaper tape with 5mm to 10mm conductive strips perpendicular to the edge of the sandpaper spaced a maximum of every 75mm. Exert a force of (0.63±0.05)N on the test sample by the combination of the bracket, support rod and pivoting arm, draw the sandpaper abrasion tape under the test sample at a rate of (1500±75)mm/min and record the length of sandpaper abrasion tape necessary to expose the conductor. Move the test sample 50mm and rotate the test sample clockwise 90°. Repeat the procedure for a total of four reading. The mean of the readings shall determine the resistance to sandpaper abrasion.
