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.

Of the environmental factors which affect the mechanical properties of wood, one of the most important is moisture content. The development of standardized procedures for adjusting lumber strength for changes in moisture content is reviewed. Historically, the adjustment procedures for flexural properties in ASTM standard D 245-74 are shown to have been based on tests of lumber in structural sizes, with the magnitude of the adjustment being dependent upon the thickness and apparent strength of the piece. It is indicated that current adjustment procedures are based on mean strength properties that, when compared to tabulated average strength properties obtained from tests of full size lumber, were considered to be conservative for most species. A review of recent research results indicates that the magnitude of the seasoning adjustment for tensile and flexural strength of lumber is dependent upon the initial strength of the piece in the green condition. The need for an analytical model for describing the moisture content-strength relationship is stressed. Obstacles to the establishment of an effective model are discussed. Recommendations for future research in order to some of these obstacles are given. (Author).
