Pulps - Determination of stock concentration

This document outlines a procedure for determining the concentration of pulp suspensions within a manufacturing or testing environment. The methodology provides a systematic approach to measure the amount of solid material present in a water-based mixture, which is a critical parameter for controlling papermaking processes and ensuring product quality. By utilizing specific equipment and defined measurement techniques, the described protocol enables laboratories to achieve consistent and comparable results across different facilities. The approach covers the necessary preparations, including sample handling and dilution requirements, to ensure accuracy during the analysis. It is applicable to a wide range of fibrous materials used in the production of paper and paperboard. Adherence to these established steps allows operators to monitor process variables effectively and make informed decisions regarding pulp quality control. The guidelines facilitate international consistency in testing methods, supporting trade and technical cooperation among various industries involved in the pulp and paper sector. This resource serves as a reference for laboratories aiming to standardize their concentration measurement practices.
