GB/T 8940.2-2002 "Preparation of Pulp Brightness (Whiteness) Test Specimens" specifies the preparation method of test specimens for the determination of pulp brightness (whiteness). It is applicable to wood pulp, bamboo pulp, grass pulp, and cotton or hemp long-fiber pulp cut to an appropriate length. The standard clarifies key steps and operational requirements, such as specimen sampling, disintegration, sheet formation, and drying, ensuring that the prepared specimens are uniform and representative. This lays the foundation for the accuracy and comparability of subsequent brightness (whiteness) test results.
