- Scope
- 1.1 These test methods cover the determination of various strength and related properties of wood by testing small clear specimens. 1.1.1 These test methods represent procedures for evaluating the different mechanical and physical properties, controlling factors such as specimen size, moisture content, temperature, and rate of loading. 1.1.2 Sampling and collection of material is discussed in Practice D5536. Sample data, computation sheets, and cards have been incorporated, which were of assistance to the investigator in systematizing records. 1.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. When a weight is prescribed, the basic inch-pound unit of weight (lbf) and the basic SI unit of mass (Kg) are cited. 1.2 The procedures for the various tests appear in the following order: Sections Photographs of Specimens 5 Control of Moisture Content and Temperature 6 Record of Heartwood and Sapwood 7 Static Bending 8 Compression Parallel to Grain 9 Impact Bending 10 Toughness 11 Compression Perpendicular to Grain 12 Hardness 13 Shear Parallel to Grain 14 Cleavage 15 Tension Parallel to Grain 16 Tension Perpendicular to Grain 17 Nail Withdrawal 18 Specific Gravity and Shrinkage in Volume 19 Radial and Tangential Shrinkage 20 Moisture Determination 21 Permissible Variations 22 Calibration 23 1.3 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.
