Proposals pass towards AWPA standardization

At the fall technical committee meeting of the American Wood Protection Association (AWPA) held in Santa Fe, NM Sept 27-30, Bob Baeppler, Viance Business Development Manager for the Industrial Division, presented proposals to three different technical committees.

The proposals were:

  1. In Committee “P-5 Methods for Chemical Analysis of Preservatives,” a proposal to modify Standard A71 to remove the requirement to split cores when determining the penetration of DCOI and other oil-borne preservatives in wood.
  2. In Committee “T-4 Poles and Posts,” proposals to add DCOI-A to the preservatives listed for the treatment of southern yellow pine laminated poles, ponderosa pine poles, Alaska yellow cedar poles and red cedar poles (UC4C) in U1 Commodity Specification D.
  3. In Committee “T-8 Composites and Manufactured Products,” DCOI-A was added to the preservatives listed for the treatment of southern yellow pine laminated timbers (treated after gluing) in U1 Commodity specification F.

All proposals passed unanimously. This is the first and most important step in standardization into the AWPA Book of Standards. The proposals now go back to committee for a letter ballot. The third step in the process takes place in January when the Executive Committee meets to ratify the ballot followed by publication in the AWPA Book of Standards.

DCOI is already listed in the AWPA Book of Standards for the treatment of southern yellow pine poles, Douglas fir poles, Douglas fir laminated poles, Douglas laminated timbers, crossties, and timbers (Douglas fir, western hemlock, and western larch), red pine poles, red cedar poles, western larch poles, and lodgepole pine poles.
