Dr. Jieying Wang, Senior Research Scientist at FPInnovations, and Dr. Jong Bun Ra, Professor of Gyeongnam National University of Science and Technology (GNTECH), in collaboration with Canada Wood Korea, have conducted the 5th year field inspection of Canadian wood pressure treated to the CSA O80 Standards on October 2, 2015 at the field testing site near Jinju city, located in southern province of Korea.

The result of the 5th year inspection has been very much anticipated because of its implications for the long term durability and performance of two of the most common and refractory Canadian wood species, White Spruce and Hemlock. The specimens were treated in Canada with ACQ and CA and brought to Korea five years ago. They were tested for penetration and retention in Korea and placed in above ground exterior construction and ground contact service conditions at the site.

The inspection by Dr. Wang and Dr. Ra has revealed that all the treated specimens are in good condition while controls were attacked by fungi and termites proving that CSA O80 Standards can be a viable option for expanding use of refractory species in Korea without sacrificing performance. The results of testing will be presented and its implications will be discussed in a technical seminar planned for industry, academia, researchers and regulators.
