Glossary
COF
Coefficient of Friction, µ
COF Type
The COF type. Supported types are DCOF, SCOF and TCOF.
DCOF
Coefficient of Dynamic Friction; also known as coefficient of kinetic fric-
tion µ
k
Method
The instruction or procedure, how the COF shall be measured. Often
published as standard. In the TRACSCAN instrument, all (applicable) pa-
rameters of a method are represented by a test program.
NFSI
National Floor Safety Institute
SBR
Styrene Butadiene Rubber. A common material for the test foot liner.
Scale
The scale that is used to visualize the Coefficient of Friction values. If the
scale is defined by a standard, the scale also defines (and shows) thresh-
old values for the appraisal of the average Coefficient of Friction.
SCOF
Coefficient of Static Friction; µ
0
TCOF
Transitional Coefficient of Friction; the method associated with this co-
efficient is also known as Dynamic Heel Impact or Flying Start
Test Foot
The piece that is plugged to the bottom of the TRACSCAN. The test foot’s
liner models a shoe sole.
Test Program
The set of parameters that are used by the instrument if a measurement
is started. Can be seen as representation of a method.
