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:

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

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 and health practices and determine the applicability of regulatory limitations prior to use.
