ActivePaper and board - Measurement of hygroexpansivity - Part 2: Hygroexpansivity up to a maximum relative humidity of 86%
纸和纸板 湿膨胀率的测定 第2部分：最大相对湿度增加到86%过程的湿膨胀率
Application Summary AI generated
This standard specifies a method for measuring the dimensional changes (hygroexpansivity) of paper and board when exposed to a controlled increase in relative humidity up to 86%. It is applied in the paper manufacturing and converting industries to evaluate the stability of materials used in products like printing paper, packaging board, or labels, where humidity-induced expansion can cause curling, misregistration, or delamination. The test is critical for quality control and product development in environments with fluctuating humidity, such as offset printing or humid storage conditions.
