1.1 These test methods cover determination of the bending strength and stiffness of wood poles. Knowledge of these properties is used in providing for reliable and economical design with poles of different species, size, or grade.

1.2 Two test methods are included: the cantilever test method and the machine test method.

1.3 Provision is also made for extracting small clear specimens from the butt section and determining static bending and compression parallel to grain strength values in accordance with Test Methods D 143.

1.4 The procedures specified in these test methods apply to tests of either treated or untreated material.
