Additional information

1. Scope

Note 1—A proof load may be used which will permit the determination of a specified strength percentile without testing the total sample to destruction. Designing a test program on the basis of proof loading can be complex, requiring consideration in relation to the objectives of the test program. Guidance on this matter can be found in the paper by Johnson.

1.1 These test methods cover the determination of the mechanical properties of stress-graded lumber and other wood-base structural material.

1.2 These test methods appear in the following order:

	Section
Bending edge-wise	6-11
Bending flat-wise:
Center point loading	12-17
Third point loading	18-23
Axial strength in tension	24-29
Axial strength in compression	30-35

1.3 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.
