The procedures described in this practice are intended to be used to establish appropriate allowable unit stresses, moduli of elasticity, and specific gravity for mechanically graded solid sawn lumber. An on-going quality control program to monitor compliance with the assigned grade properties is required.
Область применения1.1 This practice covers the methodology of grade qualification, assignment of design properties, and requirements for the quality control of mechanically graded solid sawn lumber.
1.2 This practice acknowledges alternative methods for the assignment of specific properties. These methods are assignment by test, relationship to other properties, and by procedures in other appropriate standards.
