Determination of Fungitoxic Value of Preservatives in Laboratory Wood-Block Tests
Keywords:
CCA, toxicity data, agar-block method, <i>Serpula lacrymans</i>, statistical estimationAbstract
Laboratory-modified agar-block tests were made to determine the fungitoxic value of the wood preservative CCA against the test fungus Serpula lacrymans. The procedure applied to determine the results accounted for different standards: EN (toxic limit), ASTM (threshold retention), GOST (threshold retention and protection probability), PN (toxic dose), and JIS (value of efficiency). In order to improve the objectivity and repeatability of the toxic value results, statistical methods were used. Regression equations related sample mass loss and preservative retention.References
