ASTM F410-08
(Test Method)Standard Test Method for Wear Layer Thickness of Resilient Floor Coverings by Optical Measurement
Standard Test Method for Wear Layer Thickness of Resilient Floor Coverings by Optical Measurement
SIGNIFICANCE AND USE
This test method is applicable for wear layers with a minimum thickness of 0.001 in. (0.02 mm) to a maximum thickness of 0.1 in. (2.54 mm), where measurements within 0.0005 in. or 0.01 mm are tolerable.
SCOPE
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 the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
