ISO 15989 Automatic Tilt Contact Angle Measuring Instrument Contact Angle Tester
1. Preface
Contact
Angle
refers
to
the
tangent
of
gas-liquid
interface
made
at
the
intersection
of
gas,
liquid
and
solid.
This
tangent
is
in
the
Angle
theta
between
the
liquid
side
and
the
solid-liquid
boundary.
Contact
Angle
measurement
is
the
main
method
of
