[Technical Note] The Effect of Variables on Laboratory Termite Testing: Part II—Effect of Grain Orientation of Test Blocks

Abstract

Abstract The effect of test-block grain orientation on laboratory termite tests using American Wood-Preservers' Association Standard E1-97 was evaluated using Coptotermes formosanus. This research revealed that testing of samples with the 6-mm direction in either the longitudinal or the tangential direction was appropriate. The E1 standard was subsequently modified to allow either.
