ASTM F2421-05(2011)

1.1 This test method establishes the procedures for determination of both dimension (length and width) and squareness of resilient floor plank. This test method is intended for use with rectangular plank up to 36 in. (915 mm).

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. Specific precautionary statements are provided in applicable sections of this test method.

1.2 The values stated in inch-pounds units are to be regarded as the standard. The values given in parentheses are for information only.

The combination of both dimensional and squareness of resilient floor plank is an important consideration because installed flooring may exhibit an objectionable appearance when either or both characteristics deviate from established tolerances. This test method provides a means of determining actual dimensional and squareness by using a single apparatus and procedure.
