ActivePaper and board—Accelerated ageing (100℃)
纸和纸板 加速老化（100℃）
Application Summary AI generated
This standard specifies a method for artificially accelerating the natural ageing of paper and board by exposing them to a constant temperature of 100°C. It is applied in the paper industry to predict the long-term stability and durability of paper products, such as archival papers, packaging materials, and printing papers, under controlled laboratory conditions. The test helps manufacturers and quality control labs assess how paper properties like strength and color change over time without waiting for real-time ageing.
