    Significance and Use

    6.1 The flexural properties established by this test method provide:

    6.1.1 Data for use in development of grading rules and specifications;

    6.1.2 Data for use in development of design values for structural members;

    6.1.3 Data on the influence of imperfections on mechanical properties of structural members;

    6.1.4 Data on strength properties of different species or grades in various structural sizes;

    6.1.5 Data for use in checking existing equations or hypotheses relating to the structural behavior of beams;

    6.1.6 Data on the effects of chemical or environmental conditions on mechanical properties;

    6.1.7 Data on effects of fabrication variables such as depth, taper, notches, or type of end joint in laminations; and

    6.1.8 Data on relationships between mechanical and physical properties.

    6.2 Procedures are described here in sufficient detail to permit duplication in different laboratories so that comparisons of results from different sources will be valid. Where special circumstances require deviation from some details of these procedures, these deviations shall be carefully described in the report (see Section 11).

    1. Scope

    1.1 These test methods cover the evaluation of lumber and wood-based materials in structural sizes by various testing procedures.

    1.2 The test methods appear in the following order:

     

    Sections

    Flexure

      4 – 11

    Compression (Short Column)

    13 – 20

    Compression (Long Member)

    21 – 28

    Tension

    29 – 36

    Torsion

    37 – 44

    Shear Modulus

    45 – 52


    1.3 Notations and symbols relating to the various testing procedures are given in Appendix X1.

    1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.5 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.
