ASTM G154

ASTM G154 is a standard test method developed by ASTM International to evaluate the durability of materials when exposed to artificial weathering, specifically ultraviolet (UV) light. It simulates the damaging effects of sunlight on products, helping manufacturers assess how materials like plastics, paints, and coatings resist fading, discoloration, and degradation over time. By using specially designed test apparatus, ASTM G154 enables consistent and controlled experiments, allowing for a better understanding of how products might perform in real-world outdoor conditions, ultimately leading to improved quality and longevity.
