The sandpaper abrasion test apparatus is designed according to ISO6722-1 clause 5.12.4.1 figure 6, ISO 19642-2 clause 5.3.2.4 and figure 3, GB/T25085, QC/T730, JASO D608, JASO D611, SAE J1127, SAE J1128 and JIS C3406. The sandpaper abrasion test is for verifying that the resistance of the cable insulation to sandpaper abrasion.
Measure the “resistance to sandpaper abrasion” using 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, the total vertical force exerted on the test sample shall be the combination of the force exerted by the bracket, pivoting arm, support rod and additional mass. Mount the test sample taut, without stretching, in a horizontal position using an area of the sandpaper abrasion tape not previously used. Place the additional mass and bracket on top of the test sample. 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.
