This paper discusses contributions developed at the Forest Products Laboratory that have advanced utilization of the Weibull distribution in wood engineering. The increased use of the Weibull distribution in wood engineering primarily occurred since 1975. The goals of this paper are to (1) unite, clarify, and simplify information published in several sources into a cohesive summary, (2) advance the use of this research through corrections of misinterpretations and errors of some earlier publications, and (3) introduce some potential new concerns about the use of the Weibull distribution in some ASTM standards that present an opportunity for further research.
