抄録

In the testing of wood for resistance to wear, a laboratory test should simulate the condisions of service in timber floors. In this respect the two abrasive action-one the impact of the heel and the other scuffing action by the sole of footwear-should take into consideration. This paper is a report includig: (1) the trial machine, designed by author, for measuring wear resistance of walkway materials, specially timber flooring with two abrading apparatus-one a iron board and wire-brushes to abrade flooring surfaces biting the abrasive sand and the other the group of iron cylinders each studded with three pan head studs impart impact blows the flooring surfaces-with which a comparatively similar conditions to service wear is obtained; and (2) the laboratory abrasion test results with this machine of some soft and hard wood and the relation between specific gravity and loss in thichness.
