(Test Method)Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products
Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products
SIGNIFICANCE AND USE
5.1 The localized crushing behavior of wood or wood-base products beneath a fastener where the fastener does not bend provides a material property that is used in theoretical models for connections where crushing or fastener bending, or both, occur. These theoretical models are used to establish design values for wood and wood-base connections. The tests are appropriate when studying the effects of such variables as fastener diameter, fastener hole size, moisture content, specific gravity, and grain direction on the dowel-bearing strength.
SCOPE
1.1 This test method provides the basic procedure for evaluating dowel-bearing strength of wood and wood-based products. The bearing test results are used to determine the static load resistance and deformation characteristics of connections in wood and wood-base products resulting from the application of a load transmitted by a fastener inserted into a predrilled hole, or driven without drilling. Methods are given for preparing specimens with predrilled holes larger than the fastener diameter and specimens with holes produced by inserting fasteners in holes smaller than the fastener diameter. The methods apply to fasteners such as dowels, bolts, nails, spikes, drift pins, screws, lag screws, and staples.
1.2 This test method also provides the basis for determining the compression behavior of wood products beneath a laterally loaded fastener where the thickness of the product and the diameter of the fastener are such that minimal bending of the fastener occurs during testing.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.

the fastener does not bend during loading.
3.1.2 dowel-bearing strength—yield load obtained from the load-deformation curve of a dowel-bearing test divided by the dowel
diameter and specimen thickness.
4. Summary of Test Method
4.1 Specimens consisting of a single rectangular parallele-piped member with a fastener hole perpendicular to the faces of the
member are evaluated for the resistance to embedding the fastener into the fastener hole, so as not to bend the fastener. Tests are
conducted on a testing machine at a uniform deformation rate, while loads and deformation are measured at various intervals.
Supplementary physical properties of the wood or wood-base member are also determined.
