The suitability of high pressure sap-displacement for the retention of UK grown spruce and pine
1990 - IRG/WP 3595
The concentration and radial distribution of copper, chrome, arsenic (CCA), and the moisture content and depth of radial checking in UK grown, field exposed spruce and pine poles treated by high pressure sap-displacement are examined. The concentration of CCA elements in samples obtained from increment cores is similar in Norway spruce, Scots pine and Corsican pine but is significantly lower in Si...

Field evaluation of CCA movement in sap-displaced copper chrome arsenic treated softwood poles
1989 - IRG/WP 3539
Commercial sap-displaced UK grown Scots and Corsican pine, and Sitka and Norway spruce poles were exposed in a field site at Dundee, Scotland and radial distribution profiles of CCA monitored prior to implantation and after subsequent field exposure. Results show that groundline levels of all preservative elements were higher after 1 and 2 years field exposure compared with those recorded prior to...

Studies in an accelerated soil bed facility on the decay susceptibility of U.K. grown spruce and pine poles treated with copper/chrome/arsenic (CCA) by pressurised sap-displacement. Part 1: Setting up of soil beds and initial soft rot results
1990 - IRG/WP 2344
The paper describes the methodology used in the construction and early operation of an accelerated soil bed facility used to examine the decay susceptibility of U.K. grown Scots and Corsican pine and Sitka and Norway spruce treated with C.C.A. by high pressure sap-displacememt. The design and control of the facility as well as the preparation, soil exposure and soft rot decay analysis of quarter p...
