UV Test Chamber GB/T2423.1.2-2001 GJB150.5 GB10592-89 Environment
Test Machine
Description:
UV weathering test chamber is to simulate the sun lighting, and it’
s specialized in the simulation of products in outdoors for a long
time. The ultraviolet radiation in the sun is destructive on its exposure, only a few days or weeks, the
equipment can
reproduce the destruction outdoors for months or years. And then to
see whether the product has fading, discoloration, brightness decline, powder,
cracking, blurred,brittle, decreased strength and oxidation phenomena, while it can
reproduce the
destruction of rain and dew.
There are several different types of fluorescent UV lamps that have
unique spectral characteristics. Fluorescent black lights, referred
to as UV-A lamps, are available with peak emissions of 340 nm – 370
nm (e.g., UVA-340 and UVA-351). In the UVA-340 lamp, the short
wavelength irradiance simulates that of direct solar radiation
below 325 nm. Fluorescent UV-B lamps (UVB-313), with a peak around
313 nm, have nearly all of their energy concentrated between 280 nm
and 360 nm. A large percentage is at wavelengths shorter than what
is present in natural sunlight. There is very little radiation with
wavelengths longer than 360 nm. Reversals in the stability ranking
of materials have often been reported between laboratory
accelerated and outdoor tests when the accelerated test uses UV-B
lamps. This occurs because of the large amount of short wavelength
UV and the lack of long wavelength UV and visible radiation; the
mechanisms of degradation may be significantly different from those
of the “natural” tests.
Equipment summary:
QUV UV aging testing machine can simulate the sun, rain and dew to
damage the material, QUV 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.
