ISO 4892-1-2016 UV Weathering Accelerated Ageing Test Chamber
ISO 4892-1-2016 UV Weathering Accelerated Ageing Test Chamber
Product Description
This equipment uses a fluorescent ultraviolet UV lamp to simulate the effect of sunlight, uses condensed moisture to simulate rain and dew, and puts the test material in a cycle program of alternating light and moisture at a certain temperature for testing.
It can detect paint, ink, paint, resin, plastic, rubber, printing and packaging, aluminum profile, adhesive, automobile, motorcycle industry, cosmetics, metal, electronics, electroplating, medicine, etc.
Used to simulate the harm caused by sunlight, rain, and dew.
UV can reproduce the hazards that occur outdoors for months to years in a few days or weeks. The hazard types include: fading, discoloration, loss of gloss, chalking, cracking, turbidity, bubbles, embrittlement, strength decline and oxidation.
The UV weathering accelerated ageing test chamber conforms to standards:
GB/T 14522-93 “Accelerated Weathering Test Method for Plastics, Coatings, Rubber Materials Used for Machinery Industrial Products”
ASTM G154 “Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Nonmetallic Materials1”
ISO 4892-1-2016 “Plastics-Methods of exposure to laboratory light sources-Part 1: General guidance”
ISO 11507 -2007 “Paints and varnishes - Exposure of coatings to artificial weathering - Exposure to fluorescent UV lamps and water”
ASTMD 4329-2005 “Standard Practice for Fluorescent UV Exposure of Plastic”
