The method described is applicable to all kinds of paper, board and pulps, except for papers used for electrical purposes. For high purity papers used for electrical purposes, the method used should be that given in IEC 554-2. Conductivity is measured by means of a conductivity meter or resistance bridge, using alternating current.
