1.1 This test method covers the determination of pile thickness of finished multilevel 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 multilevel loop pile constructions.

Determination of pile thickness of multilevel pile yarn floor coverings was previously contained within Test Method D 418. For user convenience, Subcommittee D13.21 subdivided Test Method D 418 into separate standards of which this test method is one.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only and may be approximate.
