1.1 This terminology covers a repository of definitions essential for the business of Committee D07.1.2 The following criteria shall be followed by Subcommittee D07.91 in selecting terms and associated definitions for inclusion in this terminology.1.2.1 Terms and associated definitions shall be selected if they are in general use in the conduct of the standards over which D07 has jurisdiction.1.2.2 Terms and associated definitions in general industrial or technical use that are not unique to wood or wood-based products are not included.1.2.3 Terms and associated definitions that are unique to a single D07 standard and defined therein or generally understood or adequately defined in other readily available sources may not be included in this terminology.1.3 When a term is used in an ASTM document for which Committee D07 is responsible, it is included in this terminology only when judged an essential term by Subcommittee D07.91.1.4 A definition is a single sentence with additional information included in discussion notes.1.5 Terms and definitions shall be reviewed every 5 years; the year of last review is appended.1.6 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.

4.1 Many physical and mechanical properties of wood and wood-based materials change in response to the environmental equilibrium moisture content, and any comparison of these properties must take moisture content into account. A consistent base for comparison among different test samples and different laboratories is necessary. Shrinkage and dimensional change in particular are dependent on moisture content, and tests involving their measurement must be conducted with good equilibrium moisture content control. Conditioning can also be important in industrial settings where there are optimum moisture content levels for many products and processes, and conformance to these levels can reduce losses in quality and yield.1.1 This guide covers standard procedures for conditioning and equilibrating wood and wood-based materials to constant moisture content. The procedures apply to solid wood, wood-based fiber and particulate materials and panels, and wood products containing adhesives. They are intended for use in research and development activities, testing laboratories, quality control, and for all other classes of producers and users. This guide includes background material on the importance of moisture content control, important definitions and technical data, possible types of apparatus, procedures, and the importance of conditioning time. Users should recognize that the necessary degree of precision and bias varies with the intentions of the users. Some research and testing, for example, might require very close control of moisture content, whereas control in an industrial storage facility might not require such close control. This guide offers procedures that include these different requirements.1.2 The values stated in SI units are to be regarded as standard. The values of temperature in degrees Fahrenheit given in Table X1.2 are mathematical conversions that are provided for information only and are not considered standard.1.3 The following safety hazards caveat pertains only to the procedure section, Section 6, of this guide. 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.1.4 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.
