TAPPI T 204 cm-07 provides a laboratory procedure for measuring solvent-soluble, nonvolatile material in wood and pulp. The method covers solvent selection, extraction apparatus, reagents, safety precautions, sampling, Soxhlet extraction, evaporation, weighing, calculation, reporting, and precision data. It addresses ethanol-benzene, dichloromethane, and acetone extraction systems and supports analysis of resins, fatty acids, waxes, sterols, hydrocarbons, and other extractive substances.
This four-page PDF standard is intended for pulp and paper laboratories, wood products testing, quality control, research, and technical organizations that require a documented procedure for solvent extractives analysis.
Application Scope: Use for testing solvent-soluble extractives in wood and pulp samples within laboratory, manufacturing, research, and quality assurance environments.
