New Test Method Will Evaluate Wood Flexibility

A task group of Committee D07 on Wood is developing a “Standard Test Method for Nondestructive Evaluation of Wood-based Flexural Members Using Transverse Vibration.”

“The advantage of this test method is that it is a relatively quick way to measure the modulus of elasticity (MOE) of lumber products,” says Robert J. Ross, U.S. Department of Agriculture Forest Service, Madison, Wis. “This type of test method has been used for over forty years to assess the MOE of lumber. It is frequently used by lumber grading agencies, university laboratories, and federal research groups to test lumber.”

Ross is project leader of Wood Engineering and Drying Systems Design Criteria with the USDA Forest Products Laboratory. As task group chairman, he invites interested parties to develop the standard, including non-ASTM members who can participate electronically without traveling to meetings.

Contact Robert J. Ross, USDA Forest Service, Forest Products Laboratory, Madison, Wis. (608/231-9221). Committee D07 meets April 21-24 in Madison. For meeting or membership details, contact Maxine Topping, manager, Technical Committee Operations, ASTM International (phone: 610/832-9737).
