1. Scope*
1.1 This test method covers determination of the coefficients of starting and sliding
friction of plastic film and sheeting when sliding over itself or other substances
at specified test conditions. The procedure permits the use of a stationary sled with
a moving plane, or a moving sled with a stationary plane. Both procedures yield the
same coefficients of friction values for a given sample.
NOTE 1 For the frictional characteristics of plastic films partially wrapped around a cylinder, or capstan, see Test Method G143 under the jurisdiction of ASTM Subcommittee G02.50.
