ISO 4892-1 PLC & Touch Screen UVA UVB Accelerated Aging Environmental Test Chamber
Product Description:
The UV resistance to natural weathering test chamber is mainly used for the artificial accelerated test of plastics, coatings, rubbers and other materials under simulated conditions. This equipment only takes a few days or weeks to reproduce the operating conditions that occur outdoors for months or even years, Or aging and other laboratory damage to various parts, including fading, discoloration, tarnishing, chalking, cracking, cracking, wrinkling, blistering, embrittlement, reduced strength, oxidation. Test results can be used to select new materials, improve existing materials, or evaluate changes to material formulations.

Test Principle:
This machine uses imported fluorescent UV lamp as light source, and simulates ultraviolet radiation such as natural sunshine, night coldness, condensation, rain, etc., to accelerate the test of material resistance to natural weathering, so as to obtain the results of material weathering. It can help you select new materials, improve existing materials, and evaluate how this affects product durability.
Standards & Clauses:
What is the difference between UV-A340 and UV-B313?
◆ Commonly used UV lamps are mainly UV-A340 and UV-B313.
◆ UV-A-340 is the best choice to simulate the solar ultraviolet. It perfectly mimics the spectrum of sunlight in the critical short wavelength range (closer to the solar spectrum), i.e., the spectrum in the wavelength range of 295-360 nm, with UVA-340 producing only the spectrum of ultraviolet wavelengths that can be found in sunlight.
◆ UV-B-313 simulated solar ultraviolet aging intensity is greater than UV-A, the damage intensity is far greater than UV-A. Suitable for maximum acceleration of UV weathering tests and fast delivery of test results. It uses shortwave ultraviolet rays that are stronger than those common on Earth. While these much shorter than natural wavelengths of UV light can maximize the speed of testing, it can also cause inconsistency and actual degradation of certain materials.
