GB/T 42949-2023 "Leather — Tests for colour fastness — Colour fastness to rotational rubbing" specifies a method for determining the colour fastness of leather to rotational rubbing. The test involves using a standard rubbing head to apply a fixed pressure and rotational speed to the surface of the sample for a specified number of cycles. The staining grade is then assessed, simulating scenarios such as repeated localized friction on leather shoes, bags, and similar items.
