- Abstract
- Indentation and recovery determinations for loads ranginf rom 25 pounds to 200 pounds on a flat-ended pin 1/4 inch in diameter were made on 23 floor coverings at a relative humidity of 65 percent and temperature of 72 deg F. Indentaion readings were taken for each load at intervals of time up to 30 minutes and then recovery readings at intervals of time up to 120 minutes. Various types of floor coverings were teted, such as asphalt tile, pressed fiber board, linoleums, felt-base floor coverings having various wearing surfaces, rubber, and wood. A description of the apparatus and the procedure used are given. The results are presented in graphic form to show the relative merits of the various floor coverings with respect to initial and 30-minute indentation under various loads and the recovery after removal of the load.
