A. Product Introduction
GC-NHB-A type yellowing resistance test chamber is used to simulate the ultraviolet radiation and heat of
sunlight. The sample is exposed to ultraviolet radiation and temperature in the machine. After a period of time, the
degree of yellowing resistance of the sample is observed (it is generally believed that the material tested in the box
at 70℃ for 3 hours is equivalent to the yellowing effect of 2 months in the natural environment) can be stained
gray as a reference. And then determine the level of yellowing.
B. Test Standards
GB/T18830 Evaluation of Anti-ultraviolet Properties of Textiles.
ASTM D1148 Standard Test Method for Rubber Aging.
ISO8580 Rubber and plastic hoses. Determination of anti-ultraviolet rays in stable state.
