    1. Scope

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

    1.1.1 These 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 SI values are given in parentheses and are provided for information only. 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 Specimens5
    Control of Moisture Content and Temperature6
    Record of Heartwood and Sapwood7
    Static Bending8
    Compression Parallel to Grain9
    Impact Bending10
    Compression Perpendicular to Grain12
    Shear Parallel to Grain14
    Tension Parallel to Grain16
    Tension Perpendicular to Grain17
    Nail Withdrawal18
    Specific Gravity and Shrinkage in Volume19
    Radial and Tangential Shrinkage20
    Moisture Determination21
    Permissible Variations22

    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.
