1.1 The rapidity and ease of application of these test methods facilitate its use as a substitute for static measurements.
5.1.2 Dynamic modulus of elasticity is often used for surveys, for segregation of lumber for test purposes, and to provide indication of environmental or processing effect.
5.2 The modulus of elasticity, whether measured statically or dynamically, is often a useful predictor variable to suggest or explain property relationships.
1.1 These test methods cover the determination of the flexural stiffness and modulus of elasticity (E) properties of wood-based materials by nondestructive testing using transverse vibration in the vertical direction.
1.2 The test methods are limited to specimens having solid, rectangular sections.
1.3 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.
1.4 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.
