Color fastness tests are methods used to determine how resistant a material or fabric is to fading or running of color when exposed to various conditions such as light, water, or rubbing. These tests ensure that the material will maintain its color over time and under different usage conditions.

The fully automatic oxygen index test is a test method for measuring the combustion performance of materials. It evaluates the flame retardancy of materials by placing them in an environment containing a mixture of oxygen and nitrogen and measuring the minimum oxygen concentration required for combustion. The test utilizes automated instruments and control systems to achieve precise and efficient testing processes.
