Pulps - Laboratory wet disintegration - Part 2: Disintegration of mechanical pulps at 20 °C

This document establishes a controlled methodology for assessing the biodegradation of mechanical cellulose under damp conditions within a laboratory setting. Specifically tailored for testing at a constant temperature of 20 °C, the standard outlines precise experimental procedures to ensure consistent and comparable results across different facilities. It defines the necessary environmental parameters, sample preparation techniques, and the criteria for measuring decomposition rates over designated time periods. The approach aligns with international practices for evaluating the environmental fate of cellulose-based materials in moist environments. By adhering to the specified protocols, researchers can generate data that reflects the material's behavior when exposed to humidity without introducing uncontrolled variables. The text focuses on the technical aspects of the test method, ensuring that the degradation process is monitored accurately according to the defined mechanical cellulose specifications. This framework supports the evaluation of how quickly the material breaks down under these specific thermal and moisture conditions, providing a standardized baseline for comparison.
