GB/T 464-2008 "Dry Heat Accelerated Aging of Paper and Paperboard" specifies the dry heat accelerated aging methods for paper and paperboard at 105°C, 120°C, and 150°C, as well as general test methods for heat-treated materials. The 105°C condition is suitable for general cultural paper, while 120°C or 150°C is applicable to high-purity paper such as electrical insulating paper. The standard clearly outlines requirements for sample handling, aging operations, and result evaluation, providing a basis for predicting the long-term stability of materials.
