In October 2004, Committee D-7 on Wood of the American Society for Testing and Materials (ASTM) is celebrating 100 years of contributions to the safe and efficient use of wood as a building material.
Committee D-7 on Wood has played a vital role in this system.
The year 1910 brought a name change for Committee Q to Committee D-7. A Standard Specification for the Grading of Yellow-Pine Bridge and Trestle Timbers was approved, and work on similar standards for Douglas-fir and western hemlock were in progress.
Rather, there was close cooperation between Committee D-7 and other organizations promoting standardization.
Input from the American Lumber Standard Committee (ALSC), the current incarnation of the Central Committee, has always been important to Committee D-7 activities, and ALSC continues to be a prominent user of D-7 standards.
As the decade opened, Committee D-7 had sired four standards related to wood preservation, which are still in print, and five standards related to solid wood.
But the slow business climate probably kept the industry component of D-7 mostly on the sidelines, and with that minimal participation no new ASTM wood standards were promulgated until 1949, well after World War II.
This standard relied heavily on the existing standards of D-7 and in turn provided guiding principles for published trade association grading rules.
It is clear from the literature of the first quarter of the 20th century that FPL played a major role in determining the content of D-7 standards.
