Wear Tests With the Accelerator. A. R. Macormac and F. M. Richardson. American Dyestuff Reporter, V. 46, Feb. 25, 1957. p. 149-151. Percentage of worn wool ends consistently increased with increased time in the Accelerator, indicating a good method for measuring the abrasive damage to wool fabrics in this machine.
