Summary
An extension is made to a previously proposed reliability-based procedure for characterizing the duration of load properties of wood. This extension provides a methodology for testing if two disjoint nominal populations of wood specified by modulus of elasticity have significantly different time to failure distributions at a given applied stress. This extension has practical application in the assignment of grades to structural lumber and in determining the dependence of time to failure on grade, species, and size.
