ASTM G155 is a commonly used standardized test used with Xenon-Arc. The automotive industry leans on SAE J2527 for standardized tests to predict results. Fluorescent light testing uses smaller, less expensive equipment but does not simulate the spectrum of sunlight. Methods such as ASTM G154 are sometimes used, but are known to produce results that are not representative of outdoor exposure to sunlight.
In conclusion, the industry has many tools to formulate, mold and test products for outdoor applications. Weather-resistant compounds are part of the effort to discover new and innovative solutions with BMC/SMC and can aid in their longevity in the market.
