The evaluation, procedures and recommendations are reported for the Universal Friction Testing Machine (UFTM) developed by Comstock and Wescott for NIOSH. The machine is able to determine friction coefficients of various footwear materials in contact with flooring surfaces, especially industrial surfaces at the work site, and is to serve as a universal standard for determining friction coefficient values. The machine is considered easy to operate after familiarity, calibration procedures are judged adequate, and the machine is considered capable of differentiating between slippery and nonslippery floor surfaces. Reproducibility varied plus or minus 10%. Recommendations include changes in switch location and manipulation, raising the operating controls to waist level for field operation, incorporating a maximum value recording system into the dynamic COF circuit, changes in design and preparation of footwear samples and flooring surfaces, evaluation of the UFTM prototype on floor surfaces simulating various degrees of identifiable slipperiness, use of the UFTM on floor surfaces where there has been an occurrence of slips and falls resulting in injuries, and use of the UFTM for identifying relationships between footwear materials and their configuration. Tables, graphs and photographs illustrating the testing are given. (Contract No. 210-75-
