Standard Test Method for Coefficient of Friction, Yarn to Yarn
1.1 This test method covers the measurement of frictional properties for both continuous filament and spun-staple yarns under boundary friction conditions.
1.2 This test method has been used with yarns having linear densities ranging from 1.5 to 200 tex, but may be used with yarns outside these ranges (15 to 1800 denier).
Note 1--For coefficient of friction, yarn to metal, see Test Method D3108.
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
