Abstract

This paper documents the development of procedures in American Society for Testing and Materials standards for adjusting the allowable properties of lumber for changes in moisture content. The paper discusses the historical context of efforts to establish allowable properties on a consensus basis, beginning in the 19th century. Where possible, the reasons for proposed changes in the standards are presented. The goal of this work is to foster a better understanding of how current standards have evolved and to promote reconciliation of conflicting property assignment procedures between current standards.
