 Applicable Industries:
The UV Weathering Test Machine is one of the most widely used accelerated weathering testers globally. It is commonly employed in laboratories across various industries due to its reliability and effectiveness. This equipment is ideal for testing materials like printing ink, paint, plastics, packaging, automotive parts, metal, electronics, medical devices, and more.
This machine simulates the harmful effects of long-term outdoor exposure by subjecting test samples to conditions that mimic the most aggressive elements of weathering—ultraviolet radiation, moisture, and heat. The UV accelerated weathering chamber utilizes fluorescent lamps to emit a spectrum centered around ultraviolet wavelengths. Moisture is introduced through condensation, while temperature is regulated using heaters.
Â
 Applicable Standards:
(1) ISO 48-3-2006, Plastics - Methods of exposure to laboratory light sources - Part 3: Fluorescent UV lamps;
(2) ASTM D4329-2005, Standard Practice for Fluorescent UV Exposure of Plastics;
(3) ASTM D4587-2005, Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings;
(4) ASTM D5208-2001, Standard Practice for Fluorescent Ultraviolet (UV) Exposure of Photodegradable Plastics, etc.
