Paper -- Measurement of dimensional change after immersion in water
This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
Is suitable for use with most kinds of paper. However, it may not be suitable for some papers, which soaking makes extremely fragile and causes to curl excessively. The property of dimensional change after immersion in water should not be cofused with hydroexpansivity.
