Standard Test Method for Measurement of Resilient Floor Plank by Dial Gauge

Significance and Use

4.1 The combination of both dimensional properties 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 length and width dimensions along with squareness, by using a single apparatus and procedure.


1.1 This test method establishes the procedures for determination of both dimension (length and width) and squareness of a rectangular resilient floor plank.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are provided in applicable sections of this test method.

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

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
