Standard Test Method for
STATIC COEFFICIENT OF FRICTION OF POLISH-COATED FLOOR SURFACES AS MEASURED BY THE JAMES MACHINE
This Standard is issued under the fixed designation D 2047; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parenthesis indicates the year of last reapproval.
1.1 This method covers the measurement of the static
coefficient of friction of floor surfaces by the James Machine.

3.1 Floor polishes having a coefficient of static friction, as
measured by this method, of not less than 0.5 traditionally
have been recognized as providing nonhazardous walkway
surfaces. This value of not less than 0.5 meets the
requirements for compliance to Rule 5 on “The use of terms
slip retardant, slip resistant or terms of similar import,” of
the Proposed Trade Practice Rules for the Floor Wax and
Floor Polish Industry as issued by the Federal Trade
Commission on March 17, 1953.
