GB/T 7977-2007 "Paper, board and pulps — Determination of conductivity of aqueous extracts" specifies the method for determining the conductivity of relevant aqueous extracts. It is applicable to various types of paper, board, and pulps, including electrical insulating paper and board. The method involves controlling the extraction temperature using a constant-temperature water bath and measuring the conductivity of the extract with a conductivity meter. It defines the extraction and measurement conditions as well as the treatment of results, providing a unified approach for evaluating the content of soluble electrolytes in materials.
