Yellowing Resistance Test Chamber - China

Applicable standards

HG/T3986 - ASTM D1748 - etc.

Scope of application

Test method for determining the yellowing resistance of light and white products, such as upper and bottom materials for shoes, to approximate sunlight and ultraviolet light.

According to the light-colored or white products, the phenomenon of yellow color is easy to occur in the natural sunlight for a long time, with the solar lamp and heating temperature control device to simulate the natural environment, within the specified time, observe the change of the surface color of the sample, determine the degree of discoloration of the sample, so as to determine the ability of the material to resist yellow under sunlight radiation.
