Anti-stain field trials in British Columbia
1981 - IRG/WP 3174
Four alternative anti-sap stain chemicals were subjected to a four month field evaluation during the summer of 1980. The test, established at a Vancouver Island sawmill, was designed to evaluate the potential long-term effectiveness of sodium tribromophenate (Velsicol Ltd.), Biocom XX (Bramco Industries) containing methylene bis-thiocyanate, Woodbrite NTX (Van Waters & Rogers Ltd.) containing 3-iodo-2-propynyl-butyl carbamate and Mitrol 48 (Kenogard) containing guazatine acetate and quaternary ammonium chlorides, on hemfir and Douglas fir. Sodium tribromophenate was found to give surface protection equivalent to that of chlorophenate treated controls. Biocom XX was also effective, although the active ingredient came out of solution at the required treating solution concentration. Woodbrite NTX and Mitrol 48 were found to be ineffective on either species group under the test conditions.

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 20: Report on the inspection of specimens at Sekondi, Ghana after 48 months
1985 - IRG/WP 4116
The results of the second inspection of CCA- and CCB-treated test panels exposed at Sekondi, Ghana, in June 1980, are presented. The panels of Pinus sylvestris treated with 3% CCA are stil unattacked after 48 months. Panels treated with 10% CCA and still in test (Fagus sylvatica, Pinus sylvestris and Alstonia scholaris) are still free of attack. Locol species treated with 3% CCB have all been destroyed. Of the panels treated with 10% CCB recovered from the bottom of the sea, those of Ongokea gore were shown by X-radiography to be in various stages of attack by teredinids. One recovered panel of Erythrophleum guineense and four of Mitragyna stipulosa remain free of attack. Teredinids constitute the major hazard.

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 14: Report of fifth inspection (48 months) in Australia
1982 - IRG/WP 484
This report presents the results of the fifth inspection of the IRG/ COIPM Internatlonal Marine Test specimens installed in Sydney Harbour in December, 1977. This inspection took place on 9th December, 1981, just 48 months after the specimens were installed. Earlier reports have contained full details of the treatment and installation of the specimens as well as results of all previous inspections, made after 6, 12, 24 and 36 months, as stipulated in the working plan.
