UV aging test chamber technical indicators and structure

UV aging tester is also known as UV weathering tester, UV aging tester mainly simulates the aging phenomenon of the sun's ultraviolet light on the items, as some aging phenomena occur in the outdoor sunlight, most of them are related to the sun's ultraviolet light.

UV aging test chamber reference standards:

The UV aging tester is suitable for the performance reliability test of many industrial products, with reference to GB/T14522-93 "National Standard of the People's Republic of China - Plastic, coating, rubber materials for mechanical industrial products - artificial climate accelerated test method" GB/T16585-1996 "National Standard of the People's Republic of China -Vulcanized rubber artificial climate aging (fluorescent ultraviolet lamp) test method" and GB/T16422.3-1997 "plastic laboratory light exposure test method" and other corresponding standard provisions design and manufacture;


In line with international testing standards: 

ASTM D4329, D499, D4587, D5208, G154, G53; ISO 4892-3, ISO 11507; EN 534; prEN 1062-4, BS 2782; JIS D0205; SAE J2020 and all other current UV aging test standards.


The light source of UV aging test chamber adopts 8 imported UV fluorescent lamps with rated power of 40W as the light source. Ultraviolet fluorescent tubes, distributed on both sides of the machine, each side of four. There are UVA-340 and UVB-313 light sources for users to choose the configuration;


UV-A wavelength range of 315-400nm, the lamp's luminous spectrum energy is mainly concentrated in the 340 nm wavelength;

UV-B wavelength range of 280-315nm, the lamp's luminous spectrum energy is mainly concentrated in the wavelength of 313 nm;

As the UV light energy output will gradually decay over time, in order to reduce the impact of the test due to light energy decay, so the test chamber in the eight lamps every 1/4 of the fluorescent lamp life (lamp life: 1600H), by a new lamp to replace an old lamp, its position change as follows, so that the UV light source is always composed of new and old lamps, so as to get a constant output of light energy;
