• Abstract:

  SIGNIFICANCE AND USE; 3.1 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. ; 3.2 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. ; 1.4 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.

Overview

ASTM F387-17(2022): Standard Test Method for Measuring Thickness of Resilient Floor Covering With Foam Layer sets out a standardized procedure for accurately determining the thickness of resilient non-textile floor coverings that include a foam layer. The standard, developed by ASTM International, addresses the limitations of conventional thickness measurement tools, such as hand micrometers, which can compress foam layers and produce inaccurate results. By providing a reliable and repeatable test method, this standard is essential for quality assurance and compliance within the flooring industry.

Key Topics

• Purpose and Scope:

  • Defines the requirements for measuring the thickness of resilient floor coverings with foam layers as part of their construction.
  • Applies to non-textile floor coverings where compressible foam can affect measurement accuracy.
  • Specifies that inch-pound units are standard, with SI conversions for reference only.

• Test Method Significance:

  • Ensures accurate thickness measurements without compressing the foam layer.
  • Supports manufacturers and quality control personnel with a method that combines precision, convenience, and speed.

• Apparatus and Specimen Preparation:

  • Recommends using a comparator stand with a calibrated thickness gauge.
  • Describes requirements for the presser foot and anvil to minimize measuring error.
  • Specifies specimen size and conditions for testing, including temperature and humidity.

• Reporting and Precision:

  • Outlines how to report average, minimum, and maximum thickness values.
  • Includes repeatability and reproducibility parameters based on inter-laboratory studies for enhanced reliability.

• Safety and Compliance:

  • Advises users to establish appropriate safety and health practices.
  • Developed in line with internationally recognized standardization principles, enhancing global applicability.

Applications

The ASTM F387-17(2022) standard is widely used in the following contexts:

• Quality Control for Flooring Manufacturers:

  • Ensures consistent production of resilient floor coverings meeting product specifications.
  • Provides a reference for verifying compliance with industry and project requirements.

• Third-Party Testing Laboratories:

  • Used as a benchmarking tool for independent evaluation of floor covering thickness during certification or dispute resolution.

• Contractors and Installers:

  • Assists in confirming material properties as per supplier documentation before installation.
  • Critical for projects where floor covering thickness impacts performance, such as sound attenuation, comfort, or accessibility.

• Regulatory Compliance and Specification:

  • Supports adherence to international trade guidelines as recognized by organizations like the World Trade Organization and relevant national codes.
