Product Description

ASTM G151 Uv light accelerated resistance test chamber,Uv aging testerISO 4892
This test chamber can simulate the harm caused by sun and rain, using fluorescent ultraviolet lamp to simulate sunlight, using distilled water spray to simulate the effect of rain. The tested material is placed in a light cycle program at a certain temperature for testing. The machine can be used in days or weeks to reproduce outdoor months or years of damage. Harm types include: fading, discoloration, loss of light, powder, cracking, turbidity, bubbles, brittleness, strength, decay and oxidation.

Test equipment
1. The structure of the test chamber is made of corrosion-resistant metal materials and contains 8 fluorescent ultraviolet lamps, test sample rack and temperature and time control system and indicators.
2. The lamp power is 40W.
3. The lights are mounted in a row, with each switch controlling four tubes divided into two groups.

Test condition
1. The test sample is placed on the sample rack
2. Test temperature: RT+10~70ºC can be used in the light, the temperature tolerance uniformity is ±3ºC.
3. The condensation cycle of each light can be selected as 4H light, 4H condensation or 8H light, 4H condensation and other cycles.
4. After the first light 400 ~ 450H, one or two tubes need to be replaced, and other tubes should be replaced in accordance with the lamp cycle and replacement to compensate for the loss caused by the aging of the tubes. This operation mode ensures the service life of each lamp in 1600 ~ 2000H.
Test sample and performance evaluation
1. Evaluation of appearance: the paint is mainly the evaluation of appearance, plastic and rubber can also be evaluated if necessary, check the main items are luster, color change, powder, spots, bubbles, cracks and dimensional stability. Should try to use the instrument for quantitative item detection, such as gloss meter, color difference meter.
2. Evaluation of mechanical and other properties: general rubber material tensile strength, elongation, hardness measurement, plastic measurement impact strength, elongation at break, tensile strength, bending strength, if necessary can specify other performance test items.
