ASTM D6859-03

Standard Test Method for Pile Thickness of Finished Level Pile Yarn Floor Coverings

SCOPE
1.1 This test method covers the determination of pile thickness of finished level pile yarn floor covering using a thickness measuring instrument having a stationary surface (platen), a circular pressure foot under specified force, and capable of being moved vertically above the platen.
1.2 This test method is applicable only to finished level loop and cut pile constructions with tuft heights less than 6 mm (0.25 in.).
Note 1—Determination of pile thickness of finished level pile yarn floor coverings was previously contained within Test Methods D 418. For user convenience, Subcommittee D13.21 subdivided Test Methods D 418 into separate standards of which this test method is one.
1.3 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.
