Scope

1.1 This test method covers the preparation of extractive-free wood and is applicable to all North American woods. Extractives in wood consist of materials that are soluble in neutral solvents and that are not a part of the wood.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 4.2.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Significance and Use

2.1 Extractives are materials soluble in neutral solvents. They are not generally considered part of the wood polymer structure. These materials should be removed before any chemical analysis of the wood. Ethanol-benzene extracts waxes, fats, some resins, and portions of wood gums. Hot water extracts tannins, gums, sugars, starches, and coloring matter.
