Abstract

Three methods of assessing the wear resistance of flooring materials are considered, quantitative observation of materials in conditions of severe use, simulation of the conditions of use in an accelerated laboratory test and relation of physical properties to performance in use. Eleven materials ranging from a low-priced thermoplastic tile to high-quality flexible P.V.C. flooring have been studied. The performance trials show that the range of wear resistance that can be obtained with the materials is relatively small. Generally the life of the best material was no more than three times that of the worst. The laboratory abrasion tests show that the floorings abrade at a higher rate when the artificial foot is of leather. The order of abrasion with leather is similar to that obtained in the practical trials. Examination of the tensile properties of the floorings established that a close relationship exists between the work required to rupture the materials in tension and the performance of the materials in the practical trials.
