Application Summary AI generated

This standard specifies a test method for measuring the dimensional changes (hygroexpansivity) of paper and board when exposed to a relative humidity increase up to 68%. It is applied in the paper manufacturing and packaging industries to evaluate material stability for products like printing papers, labels, and corrugated board, ensuring performance in humid environments. The test is critical for quality control and product development where dimensional accuracy under varying humidity is required.
