Cette révision d'une ancienne publication donne la résistance et les propriétés connexes de la plupart des essences commerciales canadiennes. Les données proviennent de l'échantillonnage systématique et l'essai par méthodes normalisées de dizaines de milliers de spécimens de bois sans défaut. Les principaux tableaux comprennent des données statistiques telles que le coefficient de variation et le nombre d'essais. On s'y sert du système international. Les tableaux des propriétés de résistances moyennes sont exprimés en unités impériales.
This revised version of a previous publication presents the strength and related properties of most of the woods grown in Canada. Data were obtained using standard procedures in the systematic sampling and testing of tens of thousands of clear wood specimens. The main Tables include statistical data such as the coefficient of variation and number of tests. They are presented in metric (SI) units. Tables of average strength properties in yard/pound units are also included.
The data presented in this publication are the results of a program which began more sixty years ago, to classify the strength and related properties of Canadian-grown commercial species. They have been obtained by using standard procedures in the systematic sampling and testing of tens of thousands of clear wood specimens. The main Tables include statistical data such as the coefficient of variation and number of tests. They are presented in metric (SI) units. Tables of average strength properties in yard/pound units are also included.
