Standard Test Methods for End-Joints in Structural Wood Products
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This standard provides test methods for evaluating the structural capacity and integrity of end-joints in structural wood products.
1.2 End-joints are manufactured by adhesive bonding of machined, mated surfaces at the ends of two pieces of lumber to form a joint. Typical end-joint configurations include finger joints and scarf joints. The combination of one or more end-joints and the adjoining sections of the structural wood product within the assembly is considered to be the test specimen.
1.3 Off-line test methods include: (1) Axial Tension, (2) Bending, and (3) Cyclic Delamination.
1.4 In-line test methods include: (1) Tension Proofload and (2) Bending Proofload.
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.
Significance and Use
4.1 These test methods are applicable to specimens with or without specific conditioning regimens. Tests are permitted to be performed on specimens that are not at moisture equilibrium, such as under production conditions in a plant, or on specimens that have been conditioned to specified moisture content or durability conditioning prior to testing.
4.3 These test methods do not intend to address all possible exposure or performance expectations of end-joints. The following are some performance characteristics not considered:
