The cut and direction of grain is extremely important for almost every mechanical test covered under. This standard is not included in any packages. Already Subscribed to this document. Method A provides for the use of the results of surveys of wood density involving extensive sampling of forest trees, in combination with the data obtained from standard strength tests.

We have no amendments or corrections for this standard. We have no amendments or corrections for this standard. The PD Series is equipped with computer software excellent graphical imaging and increased efficiency drilling time.

This practice presents the two standard methods for determining the strength values of clear wood of different species in the unseasoned condition, unadjusted for end use, applicable to the establishment of working stresses for different solid wood products such as lumber, laminated wood, plywood, and round timbers.

Some building codes permit reductions of certain design loads for large tributary areas and steeppitched roofs. Because of the comprehensive manner in which the density survey is undertaken, it follows that the re-evaluated strength data are intended to be representative of the forest stand, or rather large forest subdivisions.
