  • Surface to test: Polish-coated flooring such as vinyl composition tile (VCT), luxury vinyl tile (LVT), as well as marble and granite tile. Surface must be smooth.
  • This is a dry floor test using a leather test foot*
  • Tests for Static Coefficient of Friction (SCOF)
  • Translation is based on independent, third-party research from US

The James Machine Method programmed into the TRACSCAN 2.0, simulates, for use in the field, the laboratory Standard Test Method (ASTM D2047-11) for Static Coefficient of Friction of Polish-Coated Flooring Surfaces as measured by the James Machine (see photo below.) The ASTM D2047 Standard can only be done in the laboratory.

The James Machine Method is not intended for use on “wet” surfaces and must be a smooth surface. While the James Machine Method as measured by the TRACSCAN 2.0 is not an exact replication of the ASTM D2047 Standard, it is an approximate translation that closely correlates to it. The James Machine Method does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of the test method to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use.
