The D.F. Tester S-Type is designed to measure coefficient
of friction on pedestrian surfaces while the D.F. Tester was
designed to measure the dynamic coefficient of friction on
paved road surfaces. The S-Type D.F. Tester can measure the
static coefficient of friction of sidewalks, promenades, amusements,
floor surfaces of buildings, gymnasiums, etc. and the dynamic
coefficient of friction at speeds from 0 to 15 km/h. This
instrument has been developed considering bio-dynamics standards
which apply to anti-slipperiness testing devices for pedestrians.
It is designed based on the principle of the D.F. Tester,
to be portable and operator independent. Also, the coefficient
of friction of a material on a surface can easily be measured
by changing the rubber (on the rubber slider) to the desired
material (the material of a shoe sole, for example). Measurement
is possible even if the subject surface has slight unevenness,
joints or bevels. The results can be read on site upon completion
of measurement as the coefficient of friction at each speed
is graphically recorded in a continuous spectrum on the X-Y
Plotter.
