This document specifies a method for the determination of the conductivity of aqueous extracts of paper, board or pulp, these extracts having been prepared by a hot or cold method. The method 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, see method given in EN 60554‑2.
Abstract
Overview
ISO 6587:2021 specifies a standardized method for determining the conductivity of aqueous extracts from paper, board, and pulp products. This test method involves preparing extracts using hot or cold extraction techniques and measuring their conductivity at 25 °C with a conductivity meter or resistance bridge. The standard is applicable to all types of paper, board, and pulps, except for papers intended for electrical purposes, which require a different testing approach such as that described in EN 60554-2. This method provides critical data on the residual ionic impurities present in cellulose-based materials.
