1.1These test methods cover the determination of various strength and related properties of wood by testing small clear specimens.

1.1.1These 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.

1.1.2Sampling 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.

1.1.3The 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.

1.2The 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

1.3This 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.

1.4This 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.
