UV Accelerated Weathering Tester In-depth Analysis

The UV Accelerated Weathering Tester uses a fluorescent UV lamp as the light source to simulate UV radiation and condensation in natural sunlight to perform accelerated weathering tests on materials to obtain the results of material weathering. It evaluates the effects of exposure to solar radiation (UV), condensation, and spray in a single or combined environment.

UV Accelerated Weathering Tester's light source is a fluorescent ultraviolet lamp, UV Lamp, with a spectral wavelength of less than 400nm of UV energy, accounting for at least 80% of the total output light energy of the light source energy. General UV light aging test spectral wavelength range in 300-400nm, focusing on the UV aging test, the impact on product materials.

UV lamps commonly two types: UVA aging and UVB aging

Lamp UVA-340: simulate the sun's ultraviolet radiation, commonly used in the outdoor product light aging test.

Lamp UVB-313: used to accelerate the aging of materials, the study of material durability, more rapid, time-saving light aging test.

Lamp UVA-351: used for indoor environment UV aging test, simulating the sunlight filtered through the window glass after the sun spectrum.

UV light aging test conditions: lamp type, irradiation radiation intensity, temperature, time, number of cycles, non-light type (condensation, spray) conditions, etc.

UVA aging test:irradiation of UVA-340 lamp

0.68W/m2@340nm=summer noon sunlight for fast light aging test effect

1.38W/m2@340nm=2 times the maximum value of sunlight, can obtain the rapid light aging test effect

0.35W/m2@340nm = March or September daylight, common or lower UV light intensity aging test requirements

UVB aging test:UVB-313 lamp irradiance

1.23W/m2@340nm, very fast light aging test

0.48W/m2@340nm UVB-313 lamp, refer to SAE J2020 standard light length
