Standard Test Methods of Static Tests of Wood Poles

Importancia y uso:

4.1 Tests of wood poles are made to determine:

4.1.1 Data for use in establishing allowable stresses,

4.1.2 Data upon which to base economical pole line design,

4.1.3 Data on the strength properties of different species in pole sizes,

4.1.4 Data as to the influence of defects on the strength properties of poles,

4.1.5 Data as to the effect of preservatives and preservative treatments on the strength properties of poles, and

4.1.6 Data for correlating the strength properties of full-size poles with those of small clear specimens of the same species.

4.2 Treating procedures to which poles have been subjected may introduce variables that prohibit direct comparisons between different groups of data. Complete information on the treating techniques shall form a part of the test records.
