ASTM F0410-08R22 - Standard Test Method for Wear Layer Thickness of Resilient Floor Coverings by Optical Measurement

1.1 This test method covers the determination of the thickness of the wear layer of resilient non-textile floor coverings, in tile or sheet form, with or without felt backing or foam layer, by optical measurement.

1.2 This test method is applicable for wear layers with a minimum thickness of 0.0004 in. (0.01 mm) to a maximum thickness of 0.1 in. (2.54 mm), where measurements within 0.0001 in. or 0.0025 mm are tolerable.

1.3 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.

1.4 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.

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.
