ASTM F387-02(2008)
(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 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.

1.1The 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 as opposed to a micrometer caliper or other similar device.

2. Significance and Use
2.1This test method is designed to measure the vertical distance between the backing surface and an unembossed or flat area
on the wear surface. This distance or thickness is an essential parameter for product classification.
2.1 The overall thickness or caliper of resilient flooring is a basic physical property. However, conventional means of measuring

3.1 The apparatus shall consist of a comparator stand having a flat anvil base at least 6 in. (15 cm) square, equipped with a dial
micrometerthickness gage graduated to 0.001 in. (0.02 mm) and mm). The gage shall be equipped with a flat presser foot 0.250

measuring range. The force shall be obtained by means of a weight. The maximum.
3.1.1 The contact surfaces of the anvil and thickness gage presser foot shall be parallel within 0.0001 in. (0.003 mm).
4. Test Specimen
4.1 The specimen shall be approximately 2 by 4 in. (50 by 100 mm).
5. Calibration
5.1The calibration of 5.1 Calibrate the gage shall be verified by means of gage blocks or shim stock of known thickness
