F13 Committee Test Method for using a Variable Incidence Tribometer (VIT) for wet testing.
This test applies to the English XL Variable Incidence Tribometer.
Testing done by William English, inventor of the English XL.

The generally accepted minimum slip resistance reading is .50
The results indicate:
- NO-Slip increased the slip resistance of the wet tile above the dry untreated tile.
- NO-Slip increased the slip resistance when wet by over 40%.
- NO-Slip increased the co-efficient of friction of the tile when dry.
NOTE: When evaluating test results for wet surfaces, please note that none of the following F13 standards permits wet testing.
F489-96 (James Machine)
F609-96 (Horizontal Pull Slipmeter)
F1678 (Brungraber Mk I)
ASTM C1028-96
Standard test method for determining the static coefficient of friction of
ceramic tile and other like surfaces by the Horizontal Dynamometer
Pull-Meter Method.
