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”

1. The ground is level and well ventilated
2.No strong vibration around the equipment 3. No direct sunlight or other heat source radiation 4. There is no strong air flow. When the surrounding air needs to
flow forcibly, the air flow should not be directly blown onto the
cabinet;
5.No strong electromagnetic field around the equipment
6.No flammable, explosive, corrosive substances and dust around the
equipment
7. A space of 300mm should be reserved between the equipment and
walls or utensils for operation, maintenance, and ventilation. |
