This standard specifies a method for determining the potassiumhy permanganate value of pulps. It is applicable to the determination of chemical pulps with a lignin content below 6%, especially for pulps with a potassiumhy permanganate value below 35. This method reflects the lignin content or Whiteness of pulps by measuring the amount of potassiumhy permanganate consumed by pulps in acidic media. This standard provides key indicators for quality control of chemical pulps and facilitates mass monitoring during pulp production and processing.
