We are often dissatisfied with some shoes that have faded. Sometimes we feel very
ugly because of the discoloration of our shoes, and we dare not wear the discolored
shoes, which makes us feel very sick, Light Discoloration (UV) Tester is a measure of
the UV resistance of the sole and upper materials. The test equipment conforms to
ASTM, JIS, BS, ISO, ICE, UL ASTM-D1148, HG/T3689, and other international
standards, and is mainly used to test the discoloration resistance of shoe materials.
The principle is that it is equipped with sun lamps and heating devices to simulate
the natural environment. Expose the sample for a certain time, check the color
change on the surface of the sample, and then understand the anti-yellowing ability
of the sample under sunlight, which plays an important role in testing white and
light-colored upper materials, sole materials, leather, and other materials.
