Contents Introduction

Protect yourself from liability by testing products‘ static
coefficient of friction (COF) on your Michelman James Machine.
ASTM calls this test “the only method appropriate for testing
polishes for specific compliance with the D2047-93 standard.”
INTRODUCTION.................................................02
To reproduce this real-life force, a piece of flooring material is
SAFETY.................................................................03 placed on the table of the Michelman-James Machine and

DATA CARD & CONTROLS...............................04 pressure is applied, and the point at which the testing foot of
the Michelman-James Machine begins to slip is the COF. This
TEST MATERIAL SUPPLY LIST...........................05 value is displayed on the digital readout and recorded in
short-term memory.
