Paper, board and pulps. Determination of pH of salted water extracts Ingestion-build-242630 Surface water1 Scope This International Standard specifies a method for the determination of the pH of an aqueous extract of paper, board and pulps, in which the soaking and the measuring are performed in salted water (0,1 M KCl solution). This International Standard is applicable to all kinds of paper, board and pulps, but is specifically applicable to bleached pulps from virgin fibres and to pulp samples having a low ionic strength for which the pH value using
