Designation: D 1894 – 01 Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting1 This standard is issued under the fixed designation D 1894; 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 parentheses indicates the year of last reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope * D 3574 Test Methods for Flexible Cellular Materials—Slab, 1.1 This test method covers determination of the coefficients Bonded, and Molded Urethane Foams3 of starting and sliding friction of plastic film and sheeting when D 4000 Classification System for Specifying Plastic Mate- rials3 sliding over itself or other substances at specified test condi- tions. The procedure permits the use of a stationary sled with E 691 Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test Method4 a moving plane, or a moving sled with a stationary plane. Both procedures yield the same coefficients of friction values for a G 143 Test Method for Measurement of Web/Roller Fric- tion Characteristics5 given sample.
