Standard Test Method for Thickness of Resilient Flooring Materials Having Flat Surfaces

SCOPE
1.1 This test method covers the determination of thickness of resilient nontextile floor coverings including tile and sheet having flat surfaces. This test method should not be used on materials having a foamed layer.
1.2 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.
