Sandpaper Abrasion Test Apparatus As Per ISO6722-1 For Testing Auto Cable

Apparatus for Sandpaper Abrasion Test as Per ISO6722-1 for Testing Auto Cable

1. Standard conforms to 

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. 

2. Application

The abrasion test is only applicable to cables with a conductor size≤6mm²,and it is intended to verify that the sistance of the cable insulation to abarsion mees the customer requirements. A test sample of 1m in length and remove 25mm of insulation from each end.

3. Working principle

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, 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.
