UV Light Discoloration Test Chamber

UV Light Discoloration Tester is also referred to as the Anti-Yellowness Tester, which can simulate the UV (ultraviolet)radiation and heat emitted from the sun, exposing the test pieces tothis artificial environment to accept irradiation within a relatively shorttime. After hours of testing, the operator observes the degree ofdiscoloration and compares the exposed specimen with the unexposedspecimen using the Grey Scale to evaluate the performance of thespecimen's color fastness.   Light Discoloration Anti-Yellowness Tester Standards: ASTM-D1148  HG/T 3689
