(Test Method)Standard Test Method for Measuring Thickness of Resilient Floor Covering With Foam Layer
Standard Test Method for Measuring Thickness of Resilient Floor Covering With Foam Layer
SIGNIFICANCE AND USE
The overall thickness or caliper of resilient flooring is a basic physical property. However, conventional means of measuring the thickness, such as a hand micrometer or regular dial micrometer, are not applicable for foam-layer products due to the error from compressing the foam. This test method minimizes this type of measuring error and still retains the convenience and speed of measurement.
Measurement of the product thickness may be required for quality control purposes or to ensure compliance with applicable specifications.
SCOPE
1.1 This test method covers the determination of the thickness of resilient non-textile floor coverings containing a foam layer as part of the construction.
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 and health practices and determine the applicability of regulatory limitations prior to use.
