The average strength properties are obtained from wood density survey data through linear regression equations establishing the relation of specific gravity to the several strength properties.

Method B, on the other hand, provides for the establishment of tables of strength values based on standard tests of small clear specimens in the unseasoned condition for use when data from density surveys are not available.

This practice presents the two standard methods for determining the strength values of clear d25555 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.

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.

As the voice of the U. Flexure Testing uses a relatively wide bend fixture to ensure that the can achieve full rupture Method A provides for the use of the results of surveys of wood density involving extensive sampling of forest trees, in combination with the d25555 obtained from standard strength tests.
