ASTM D3500-14

Standard Test Methods for Structural Panels in Tension

SIGNIFICANCE AND USE
3.1 These test methods determine the tensile properties of structural panels in response to stresses acting in the plane of the panel.  
3.2 Test Method A—This test method is suited to material that is uniform with respect to tensile properties. It is normally applied to structural panels and plywood of clear, straight-grained veneers. It may also be used to evaluate the strength of scarf and finger joints and other manufacturing process variables that can be expected to influence the tensile properties of structural panels in a uniform manner across the width of the sheet.  
3.3 Test Method B—This test method employs large test specimens and responds well to all manufacturing variables and growth characteristics that affect the tensile properties of structural panels.  
3.4 It is recommended that where comparisons are to be made that the same test method and specimen size be used throughout. This is because the volume of material included in a test specimen can influence the tensile strength regardless of whether the material properties are uniform throughout the sheet or vary widely due to the presence of growth or manufacturing features.
SCOPE
1.1 These test methods cover the determination of the tensile properties of structural panels.  
1.2 Structural panels in use include plywood, oriented strand board and composites of veneer, and other wood-based layers  
1.3 Test Method A, Tensile Test for Small Specimens:  
1.3.1 This test method employs small specimens that should have a reduced cross section at the center of their length to avoid failure in the grip area. The transition from full width of specimen to reduced section at the center should be gradual to minimize stress concentration.  
1.3.2 When the measurements of elastic properties are to be made, the length of the reduced cross section at the center should be of sufficient length to accommodate an extensometer.  
1.4 Test Method B, Tensile Test for Large Specimens:  
1.4.1 This test method employs large specimens and responds well to manufacturing variables, panel grade characteristics, and other variables influencing the tensile properties of structural panels.  
1.4.2 The test specimens are large enough to contain the maximum sized grade characteristics found in panels. The test specimens have a constant cross section since the size and location of grade characteristics control the location of failures and the effect of stress concentration at the grips is overshadowed.  
1.4.3 This test method is recommended for the following:
1.4.3.1 Comparative tests of structural panels,
1.4.3.2 Determining the influence of any specific strength reducing variables on the tensile properties of structural panels,
1.4.3.3 Determination of tensile properties of panels for use in developing structural recommendations.  
1.5 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.  
1.6 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.
