纸和纸板 加速老化（光照条件下）
Application Summary AI generated
This standard specifies a method for accelerating the photo-induced ageing of paper and board under controlled light exposure to predict long-term color stability and physical property changes. It is applied in the paper manufacturing and archival industries to evaluate the lightfastness of documents, books, and packaging materials. The test is particularly relevant for assessing the durability of paper products intended for long-term storage or display in illuminated environments.
