JB/T 10696.6-2007Test methods for mechanical, physical and chemical properties of electric cables and wires - Part 6: Abrasion test of extruded oversheaths (English PDF)

1 Scope

This part of GB/T 10696 specifies the test apparatus, preparation of test piece, test procedure, and evaluation of test results for the test for abrasion of oversheaths.

This part is applicable to testing the abrasion resistance of plastic sheaths of cables with an outer diameter of 30 mm or more.

This part shall be used in combination with JB/T 10696.1.
