ISO ASTM Standard Light Fastness UV Exposure Aging Test Chamber For
Environmental Climatic Accelerated Weathering Testing
UV aging test Chamber is designed for evaluating the resistant
performance of non-metallic materials, organic materials (plastics,
paints, coatings, rubbers, etc.) under the specified conditions
such as sunlight, temperature, and other climatic conditions. It
creates a man-made testing environment imitating the natural light
source such as sunlight and other damages in the nature, such as rain and dew damage, to impose on the materials and to
assess the degree of color changing and fading under the
accelerated environment conditions. The chamber fully complies with
the requirements of Standard GB/T16585-1996, GB14522-93,
GB/T16422.3-97, ASTMG53 and etc., provides the best UV sunlight simulation and is easy to use and operate.

The Test Chamber is the world's most widely used weathering tester
to test types of damages include color change, gloss loss,
chalking, cracking, crazing, hazing, blistering, strength loss and
oxidation. This series is applicable for the sunlight resistant
test of nonmetallic materials and aging test of artificial light
Application: paints, coating & inks, plastic, printing package, aluminium material, adhesive, auto & motorcycle, cosmetic, metal,
electronic, electroplate, pharmaceuticals and so on.
