ASTM D5652-95(2013)

4.1 Connections are one of the weakest links in wood construction. While the strength of metal bolts and of wood or wood-based products are ascertainable, a full evaluation of the performance of the combination is only possible through the testing of a complete connection. Such variables as member thickness, member width, end and edge distances, type of bolt, fabrication tolerances, moisture content of the wood or wood-based product, preservative or fire-retardant treatment of the wood or wood-based product, and species of wood may affect connection behavior. In order to develop design criteria for established bolt types as well as those under development, the effect of these variables on connection strength and stiffness must be known. The tests described herein permit the observation of data on the strength and stiffness of wood or wood-based connections, or both, under the influence of any or all of these factors.

1.1 These test methods cover procedures for evaluating the strength and stiffness of single-bolted connections in wood or wood-based products when subjected to static loading. These test methods serve as a basis for determining the effects of various factors on the strength and stiffness of the connection.

1.2 The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are for information only.

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.
