A pressure decay test is a technique used to detect leaks by measuring a pressure change in a vessel over a desired timeframe. This test works by first using a pressure leak tester unit to fill the test specimen with air until it reaches a target pressure. Next, the pressure source is c...

With the decay test using a brown-rot fungus (Fomitopsis palustris) and a white-rot fungus (Trametes versicolor) and with the termite test using a virulent subterranean termite (Coptotermes formosanus), the metaborate-treated woods showed generally good decay and termite resistance with negligible...
