ISO 17228:2015 is the international standard for leather color fastness testing. This standard specifies a test method for testing the color stability of leather by simulating accelerated aging.

The standard mainly tests the color fastness of leather products to assess whether they will change color during long-term use. The standard covers all kinds of leather products, including shoes, handbags, furniture and more.

The test method involves exposing the sample to a controlled accelerated aging environment, such as high temperature, high humidity, ultraviolet radiation, etc., to simulate the environmental conditions encountered during prolonged use. The test cycle is set according to the different use environment.

After the test, the color change of the sample will be evaluated. The standard specifies the method of evaluation using a colorimeter or the human eye. The degree of color change will be determined by the evaluation of the color meter or the human eye.

The standard provides a standardized test method for assessing the color stability of leather products. For manufacturers, sellers and consumers, this testing method is very useful because it can assess whether the color of the product will change over the course of a long time, and thus help them make better decisions.

1 Range
The international standard specifies various aging procedures to indicate the changes that may occur when leather is exposed to a certain environment for an extended period of time. Over time, the surface color of the leather and the leather itself can change due to aging and the effect of the surrounding environment on the leather. The test conditions used depend on the type of leather and its intended use.

The procedure can also be used to test specimens for dimensional changes according to ISO 17130.
