Application Summary AI generated

This standard specifies a method for measuring the pH value on the surface of paper and board, using a flat-tipped electrode in direct contact with the moistened sample. It is applied in the paper manufacturing and converting industries to assess surface acidity or alkalinity, which affects printability, coating adhesion, and product durability. The test is particularly relevant for quality control in printing papers, packaging boards, and specialty papers where surface chemistry impacts performance.
