Full Description

This method, based on the work of Kohler and Hall (1), measures the titratable acidity or alkalinity (end point at pH 7.0) of an aqueous extract of paper (filtered and extracted by boiling water for 1 h). It specifies one extraction and so does not measure the total acidity or alkalinity of paper, for which exhaustive extraction is required.It may be applied to writing, printing, and sized industrial paper but is not intended for testing electrical insulating papers nor those containing alkaline fillers or coatings.
