ASTM F3359-19

5.1 Staples are mechanical fasteners used in wood structures. Engineering design procedures used to determine the capacities of laterally-loaded staple connections use a yield theory to establish nominal resistance (Note 1). In order to develop nominal resistance for laterally-loaded stapled connections, the bending yield moment must be known.

1.1 This test method covers procedures for determining the bending yield moment of staples when subjected to static loading. Although intended for flat crown staples identified in Specification F1667, this procedure is also applicable for staples with round wire. These staples are used in engineered wood building connection applications for which required connection capacities are specified by the designer.

1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
