Test devices and samples can be exposed to UV or full spectrum sunlight to simulate one year of sunlight in just days. Test specimens and samples can be exposed to a full spectrum simulated by special light sources.
This type of accelerated life testing shows how different materials/products will react to long term sunlight exposure.
Some of the industries requiring these types of tests include: Military & Defense, Automotive, Aerospace, Biotech, Industrial Equipment, Medical, Paint & Coatings, Plastics, Paper, Wood, Textiles, etc.
Some of the products that can be tested are: Paper, Plastics, Pulp, Wood, Outdoor fixtures/products, paints & coatings, textile & automotive parts/systems as well as many other materials that are exposed to sunlight.
These tests are also required for products that are exposed to Indoor Weathering conditions such as for carpets, office equipment, furniture, leather, etc.
Reference Test and Measurement Standards include but not limited to:
• ISO 11341 “Paints and varnishes – Artificial weathering and exposure to artificial radiation – exposure to “filtered xenon-arc radiation”
