UV Aging Test Chamber Flat Type

Product Announcement from Haida International Equipment Co., Ltd.


UV Ageing Test Chamber uses a special fluorescent UV lamp to simulate the effects of sunlight. It uses condensation humidity and water spray to simulate dew and rain. To simulate outdoor weathering,UV Accelerated Test Chamber exposes the material to alternating cycles of UV light and moisture at controlled high temperatures.

UV Aging Test Chamber is mainly used for coating ink paint, resin, plastic, printing and packaging, aluminum, adhesives, automobile and motorcycle industry, cosmetics, metals, electronics, electroplating, medicine and so on. UV Aging Test Chamber meet international standard,such as GB, GJB, MIL,ASTM,CNS,IEC,JIS,Fed Test,BS,etc.

Applications

  1. Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature.
  2. To get the results of damage after several days or weeks which is equal to expose to outside for a few months. The damages include fading, discoloration, brightness down, powder, crack, blur, brittle, strength decreases and oxidation.
  3. Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.
