Tech Trivial is the world’s leading supplier for xenon arc test chambers. Xenon arc test in compliance with ISO 4892-3 or ISO 4892-2.

Xenon arc test or Fluorescent based UV weathering test chamber in compliance with ISO 4892-3 or ISO 4892-2.

These Lamps are mounted in two banks of four each, are rich in Ultra-Violet energy between 280-350 watts at an operating voltage of 220 volts
An electrical discharge within the tube generates Ultra-violet energy at 254 Nano meters which excites the Phosphor coating causing it to fluoresce & radiate approx. 85% of the lamp’s energy between 280-350 Nano meters. In the natural sunlight spectrum below 350 NM, accounts for only about 3% of the total radiant energy.
The UV below 310 NM produced by these lamps at sample face (50mm from the lamp) is several times greater than that of natural sunlight & is the principal cause for acceleration in a test.
The fluorescent sun lamp produces virtually no significant visible or infra-red energy. Lamp Intensity normally deteriorates by about 20% during 1600 hours of useful life & the lamps are changed on a rotation basis. Every 400 hours a new Lamp is installed in each bank of 4. This method ensures reasonably uniform radiation at the sample face.
