GB/T 5399-2004 "Pulps—Determination of stock concentration" is identical to ISO 4119:1995 and specifies the method for determining the concentration of pulp stock, applicable to all types of pulp. The method involves weighing a certain amount of homogeneous pulp sample, drying it to constant weight, and calculating the concentration. It clarifies requirements such as the sensitivity of the balance, drying temperature, and time. This standard replaces GB/T 5399-1985 and provides a unified basis for concentration control in pulp production and application.
