Static Electricity 2000 Edition

D.1.54 Tribocharging.
Charge separation caused by the rub-
bing of surfaces, creating triboelectricity; also see definition
D.1.12, Charging, Triboelectric.
D.1.55 Triboelectric Series.
When different materials are
rubbed together, charge is transferred. Many researchers
working in the field of triboelectricity have set up triboelectric
series to show which combination of materials would receive
which charge. There is some agreement on the locations of
some materials, but most of the series are very dissimilar, even
when the same materials are used.
D.1.56 Upper Flammable Limit (UFL).
The highest molar
(or volume) concentration of a combustible substance in an
oxidizing medium that will propagate a flame.
