UV Accelerated Aging Test
UV Aging Test
UV Lamp Types : UVA-340, UVB-313
Application of different UV lamps :
UVA-340 :Simulated ultraviolet light in sunlight, mainly used for light aging test for outdoor products.
UVB-313: widely applied for rapid and economical test of durable material ,which will accelerate the material aging speed.
UVA-351: Used to simulate the ultraviolet portion of sunlight that passes through the window, mainly for indoor testing .
What does a complete UV test condition include?
Non illumination type (condensation and spray )
Temperature under irradiation and non illumination
Light and non light time
Testing time or testing cycling times
UVA-340 Light Irradiance :
0.68W/㎡ @340nm Equivalent to the sun in summer midday time, get quick results
1.38W/㎡ @340nm Two times the maximum value of the sun, get a quick effect.
0.35W/㎡ @340nm Equivalent to daylight in March / September, suitable for general testing or lower UV light intensity test.
UVB-313 Light Irradiance
1.23W/㎡ @340nm Very fast testing, applied to quality control or good durability material testing;
0.48W/㎡ @340nm UVB-313 Long time illumination of SAEJ2020 standard lamp tube.
