1.1This test method covers determination of the shear modulus of wood-based structural panels associated with shear distortion in the plane of the panels. The method is applicable to all types of wood-based structural panels. The grain direction or orientation of the individual plies, laminations, or layers shall be parallel or perpendicular to the edge of the test specimen. If the plies, laminations, or layers are of different material or elastic properties, the method gives the effective shearing modulus. Wood-based structural panels in use include plywood, oriented strand board, and composites of veneer and of wood-based layers.

Note 1:This test method is primarily designed for material in which the grain or orientation of the individual plies, laminations, or layers is parallel or perpendicular to the edge of the specimen. It may be used, however, for plywood specimens in which the grain is at 45° to the specimen edges if a four-ply panel with all plies of the same thickness is used. The controlling condition is that the EI (modulus of elasticity × moment of inertia) values along both diagonals shall be equal.

1.2The 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.

1.3This 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.
