A simple field apparatus for measuring relative gaff penetration and assessing the effect of additives for improving pole climbability
2000 - IRG/WP 00-20187
A simple apparatus for measuring and comparing the relative "hardness" of utility poles is described. This "slide-hammer" gaff penetration apparatus was designed as a field testing unit to measure the depth of gaff penetration into test poles after application of a uniform and reproducible force to the gaff. The apparatus is simple to use in both the laboratory and field. Data is provided for resu...

Copper naphthenate treatment for wood pols - a review and update
2012 - IRG/WP 12-30600
This paper reviews copper naphthenate (CuNap) and its utility as a treatment for wooden utility poles. One of the principal reasons that CuNap has gained market acceptance, in addition to its efficacy against decay fungi and wood-destroying insects, is its low mammalian toxicity. CuNap is a well-proven non-restricted use preservative, used extensively and specified for environmental reasons by ut...
