Abstract:
This report records the results of measurements of wear resulting from tests made upon various floor finishes applied to nine different panels of the basement floor of the R. H. Macy Warehouse at Manley Street and Anabel Ave., Long Island City, N. Y. The wear tests were made by J. G. Ahlers. The testing device used was intended to simulate the action of factory-truck wheels on the floor finish and in its operation the wheels were moved over the floor in circles about a central driven shaft. Four such wheels were operated at 18 in., 20 in., 22 in., and 24 in. from the central shaft resulting in the wear of annular grooves having 36 in., 40 in., 44 in., and 48 in. diameters.
