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).
