ISO Scrape Abrasion Tester | 413
ISO Scrape Abrasion Tester | 413
Related standard(s): ISO 6722-1
The standard specified weight is vertically applied to the tester’s needle, and the needle abrades insulate samples in their length direction.
The tester measures the number of cycles until those samples are worn, and their electrical wires appear. Once the needle makes the samples worn and contacts their wires, a test stops.
After a test is complete, the operator needs to move the samples by 100mm in length direction, rotate them by 90 degree and fix them, and repeat the test for the test cycle until the needle contacts the wires.
These procedures need to be repeated for four times in total (one rotation in an axial direction).
The minimum test cycle is taken as an abrasion cycle.
The standard specifies that the needle needs to be replaced by each sample.
