Two tests of field-cut preservatives were set up at the request of the Canadian Standards Association Technical Committee on Wood Preservation. Short lengths were cut from permanent wood foundation grade lumber, hem-fir in the west and jack pine in the east. The cut ends were coated with a range of field-cut preservatives. The samples were then laid horizontally, half buried in soil, at separate western and eastern test sites. Not all preservatives were tested at both sites. After six years exposure, chromated copper arsenate (CCA) was the only preservative performing well on both wood species.
