UV testing infographic - Micom Laboratories
The document discusses UV testing for mechanical properties and aesthetics, outlining exposure conditions and operational parameters for ASTM G154 and ASTM G155 standards. It provides guidelines on selecting the appropriate test based on indoor and outdoor requirements, along with examples of post-test measurements such as tensile strength and color change. An infographic and decision tree are included to facilitate the decision-making process for choosing between the two UV tests.
