Premium VA-A 340 UV-B 313 Accelerated Aging Test Chambers
Product Description:
The UV weathering resistance test chamber is mainly used for
artificial accelerated tests of plastics, coatings, and rubber
materials under simulated environments of sunlight, rain, and dew.
This equipment only takes a few days or a few weeks to reproduce
the working conditions in the environment that takes months or even
years to occur outdoors, or the aging of various parts and other
laboratory damages, including fading, Color changes, loss of
luster, chalking, cracking, cracking, wrinkling, blistering,
embrittlement, strength reduction, oxidation. The test results can
be used to select new materials, improve existing materials, or
evaluate changes in material formulations.

Test Principle:
This testing machine uses imported fluorescent ultraviolet lamps as
the light source, and conducts accelerated weather resistance tests
on materials by simulating ultraviolet radiation in natural
sunlight, night cooling, condensation, and rain, so as to obtain
the results of material weather resistance. It can help you choose
new materials, improve existing materials, and evaluate how to
affect product durability
Standards & Clauses:
What's different between UV-A 340 and UV-B 313?
◆ The commonly used UV lamps mainly include UV-A 340 and UV-B 313.
◆ UV-A-340 is the best choice for simulating the ultraviolet rays
of sunlight. It can perfectly simulate the sunlight spectrum in the
critical short-wavelength range (closer to the solar spectrum),
that is, the spectrum in the wavelength range of 295-360nm, UVA-340
only Produces a spectrum of UV wavelengths that can be found in
sunlight.
◆UV-B-313 simulated sunlight ultraviolet aging intensity is greater
than UV-A, and the damage intensity is much greater than UV-A. It
is suitable for the maximum degree accelerated UV aging test, and
it can quickly provide test results. The short-wavelength UV it
uses is stronger than the UV light waves commonly found on the
earth. Although these UV light, which is much shorter than the
natural wavelength, can accelerate the test to the greatest extent,
it can also cause inconsistency and actual degradation of certain
materials.
