Full title and description

ASTM D2047-17 — Standard Test Method for Static Coefficient of Friction of Polish-Coated Flooring Surfaces as Measured by the James Machine. This laboratory test method specifies the use of the James Machine to measure the static coefficient of friction (SCOF) of polish‑coated flooring surfaces for human locomotion safety and establishes a compliance criterion for nonhazardous polished walkways.

Abstract

ASTM D2047-17 defines a repeatable laboratory procedure for determining the static coefficient of friction of polish‑coated (waxed or otherwise coated) flooring surfaces using the James Machine. The method is intended for dry, polish‑coated surfaces and provides a conformance threshold (historically SCOF ≥ 0.50 for nonhazardous polished walkways). D2047-17 was published in 2017 and has been superseded by a later revision (D2047-25).

Scope

This test method covers the use of the James Machine for measuring the static coefficient of friction of polish‑coated flooring surfaces with respect to human locomotion safety. It establishes a compliance criterion for polished walkways and is limited to dry, polish‑coated surfaces where adequate contact between the machine foot and the test surface can be achieved. The method is not intended for wet surfaces or for textured/projectioned surfaces that prevent full contact with the test foot.

Key topics and requirements

• Test apparatus: James Machine (laboratory tribometer configured per the method).
• Measured parameter: static coefficient of friction (SCOF) between test foot and polish‑coated surface.
• Compliance criterion historically used: SCOF of not less than 0.50 for nonhazardous polished walkways (method‑specific and applicable only when this method is followed).
• Applicable surfaces: polish‑coated (waxed/coated) flooring surfaces; dry conditions only.
• Sample preparation and conditioning: specified to ensure reproducible contact and surface condition (machine foot material, polish application, cure/age conditions as required by the method).
• Limits and exclusions: not suitable for wet testing, highly textured or profiled surfaces that prevent adequate test foot contact.
• Precision and repeatability: precision statements and interlaboratory study results are available in associated ASTM reports for the method.

Typical use and users

Used by test laboratories, floor polish and coatings manufacturers, product development teams, safety and facilities managers, specifiers, and regulatory or procurement organizations to evaluate and demonstrate the static slip resistance of polish‑coated flooring products in dry conditions. Commonly applied when product claims regarding slip resistance of polishes or maintenance coatings must be substantiated.

Related standards

D2047-17 has been superseded by ASTM D2047-25. The method is referenced by and related to other ASTM tests and industry standards concerned with slip resistance and flooring safety; examples include various ASTM test methods and industry specifications that reference D2047 as the recognized procedure for polish‑coated surfaces. Associated ASTM research reports and interlaboratory studies provide precision data for D2047.
