Abrasive Resistance of Wood as Determined with the U.S. Navy Wear-Test Machine. Information Reviewed and Reaffirmed.

摘要

This report presents the results of an investigation at the U. S. Forest Products Laboratory concerning the feasibility of using a newly designed Navy wear-test machine for determining the abrasive resistance of wood. Closely matched samples from 21 trees, representing 15 different species, were tested. The data obtained are analyzed both with respect to the testing procedures used and as to the validity of the data obtained. Comparative tests of closely matched specimens indicate that the method of test used gives reproducible results. Further research on testing details will be required before this method of test can be standardized. The data obtained give results which place the various species tested in about the order to be expected from actual experience. The actual order of species showing about the same amount of wear is probably not significant. The much greater wear resistance of end-grain surfaces is clearly indicated for all species tested. No clear, uniform relationship between wear resistance and specific gravity was found. The results obtained indicate that this wear-test machine should be a valuable aid in making comparisons between new flooring materials and the wood species commonly used for flooring.
