GB/T 22894-2008 "Paper and board — Accelerated ageing — Moist heat treatment at 80°C and 65% relative humidity" specifies the method for accelerated ageing of paper and board by moist heat treatment at 80°C and 65% relative humidity. It is applicable to evaluating the changes in ageing performance of paper under these environmental conditions. The standard defines the basic requirements for sample preparation, treatment duration, environmental control, and performance testing after ageing, providing a basis for predicting the long-term performance of paper in use.
