UV Light Fastness Test Chamber

Name: UV Light Fastness Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

UV light fastness test chamber, a type of uv weatherometer, tests the light resistance of the material under ultraviolet irradiation, and uses 8 ultraviolet lamps UVA-340 and UVB-313 to simulate ultraviolet radiation and perform accelerated aging test on the material with additional environmental factors such as temperature, humidity and rain.

Model: UV-SI-260

Standard: ASTM G154, ASTM D 4329 – 05, ASTM C1257, ASTM C1442, ASTM C1519, ASTM C793, ASTM D1148, ASTM D3424, ASTM D3451, ASTM D4101, ASTM D4811, ASTM D6577, ASTM D6662, ASTM D750, ASTM D904, GM 9125P, ISO 29664, ISO 4892-1 (EN) (DIN)

UV Light Fastness Test Chamber Features and Benefits

1. LIB Industry uv weathering test machine equipped with UVA-340 wavelength range of 315~400nm, can better simulate the ultraviolet part of daily sunlight, UVB-313 wavelength range of 280~315nm, high energy, the aging effect on the material is stronger. Spectral power distribution does not change with lamp aging, even when used for up to 5000 hours.

2. The chamber shell adoptsA3 steel plate. The internal workroom is made of SUS304 corrosion-resistant material, which can prevent workroom from being corrosed due to long-term exposure to ultraviolet light, moisture, etc.

3.The UV light fastness test chamber is capable of complex environmental simulation, including factors such as ultraviolet light, humidity, temperature and rain, to restore the most realistic use scenario of the test piece.

4. The standard sample holder can hold up to 56 75mm*150mm samples at a time, which greatly improves the test efficiency. Custom sample holders for profile-shaped test pieces are also supported.

Configuration of UV Light Fastness Test Chamber

① Control system	Set and adjust the test temperature, irradiation time, light intensity, spray time and cycle and other parameters. The UV test chamber is equipped with four current display devices on the control system, which can detect the UV lamp failure or light source attenuation in the first time.
② Test sample area	Place the sample under test. Flat Specimen Holders (aluminum panels with rings). Customize special holder according to different specimens.
③ Radiometer	Measure the irradiation intensity of the ultraviolet lamp in the test chamber. At the same time, it can also find the aging and damage of the lamp in time.
④ Black panel	Simulate the light and temperature conditions that the sample is subjected to in the actual use environment.
⑤ Water spray system	The spray system can be set according to different spray modes, such as continuous spray, intermittent spray, etc.
⑥ Lighting system	Ultraviolet lamps are used, such as UVA lamps (wavelength 315-400nm) and UVB lamps (wavelength 280-315nm). Different types of lamps can simulate different wavelengths of ultraviolet radiation to meet the test needs of different materials.
⑦ Heating system	Using electric heating, through a heating element at the bottom of the workroom, there is water at the bottom, which generates steam when heated.
