Standard Test Method for 1% Sodium Hydroxide Solubility of Wood
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the solubility of wood in a hot dilute alkali solution. A 1 % solution of sodium hydroxide (NaOH) is used. One application is in determining the degree of fungus decay that has taken place in a given wood sample. As the wood decays, the percentage of alkali-soluble material increases in proportion to the decrease in pulp yield caused by the decay.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
