    Scope - (Show below) - (Hide below)

    1.1These test methods cover the determination of the moisture content (MC) of wood, veneer, and other wood-based materials, including those that contain adhesives and chemical additives. The test procedures appear in the following order:

    Sections

    Method A—Primary Oven-Drying Method

    5

    Method B—Secondary Oven-Drying Method

    6

    1.2The primary oven-drying method (Method A) is intended as the sole primary method. It is structured for purposes where the highest accuracy or degree of precision is needed (for example, research or calibration).

    1.3The secondary oven-drying method (Method B) is intended for the purposes where the primary procedure (Method A) is not desired or justified. Test results in this method are generally less precise than in Method A.

    1.4For materials that have been chemically treated or impregnated with creosote, petroleum, and their solutions such that the oven-drying procedures introduce greater bias than desired in the results, other methods, such as AWPA A6, are recommended.

    1.5Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

    1.6This 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.

    1.7This 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.
