Scope

This standard specifies the test method for the abrasion degree of plastic transparent films. This standard applies to biaxially oriented polypropylene (BOPP), biaxially oriented polyamide (BOPA), cast polypropylene (CPP), biaxially oriented polyester (BOPET), polyethylene (PE), coated film, matte Determination of abrasion degree and abrasion resistance of various plastic transparent films such as film. The observation method (method A) specified in this standard is applicable to the situation without a reference sample, and the gloss difference ratio method (method B) and haze difference method (method C) are applicable to the situation with a reference sample.
