Ultraviolet ( UV ) Radiation UV Aging Test Chamber For PV Modules Lab
ultraviolet (UV) radiation UV exposure aging test chambers for pv modules lab
UV Aging Test Chambe for PV Module purpose
To precondition the module with ultra-violet (UV) radiation before the thermal cycle/humidity freeze tests to identify those materials and adhesive bonds that are susceptible to UV degradation
UV Aging Test chamber for pv module apparatus
1.A temperature -controlled test chamber with a window or fixtures for a UV light source and the module under test. The chamber shall be capable of maintaining the module temperature at 60±5ºC
3.Instrumentation capable of measuring the irradiance of the UV light produced by the UV light source at the test plane of the module, within the wavelength ranges of 280nm to 320nm and 320nm to 400nm with an unceratinly of ±15% or better
4.A UV light source capable of producing UV radiation with an irradiance uniformity of ±15% over the test plane of the module with no appreciable irradiance at wavelengths below 280nm and capable of providing the necessary total irradiance in the different spectral regions of interest
5.For light sources with a negligible spectral content in the visible range the module shall be short circuited. Alternatively the module can be connected to a load sized such that the module will operate near the maximum power point . the latter is recommended for light sources emitting a significant portion of light in the visible spectrum where the module exhibits a power equal to or large than20% of its STC measured power

2.Short-cicuit or attach the resistive load to the module and mount it in the test plane at the location selected in a 1), normal to the UV irradiance beam , make sure that the module temperature sensors read 60±5ºC
3.Subject the module front side to a total UV irradiation of at least 15KW/m2 in the wavelength range between 280nm and 400nm with at least 3% , but not more than 10% in the wavelength and between 280nm and 320nm ,while maintaining the module temperature within the prescribed range

uv irradiation chambers can simulate the sun, rain and dew to damage the material,the machine using UV lamp simulate the effect of sunlight, cold rain and dew. Being tested materials are placed in a certain environment which the light and moisture are alternating. The materials are tested for several days or weeks, you can know the damage of material at outside for several months or several years, Damage types include: bleaching, discoloration, loss of light, powder, crack, turbidity, bubble-based, embrittlement, strength decline and oxidation.
Corresponding standard:
Accord with ASTMG53-77, GB,GJB,MIL,ASTM,CNS,IEC,JIS,AATCC,DIN,Fed Test,BS,SAE
Applicable industries:
accelerated weather tests is widely used in paint, resins, plastics, printing and packaging,aluminum, adhesives, auto, cosmetics, metals, electronics, electroplating, medicine, etc.
