1.1This practice covers the measurement of the angle of contact when a drop of liquid is applied to a coated surface, substrate, or preformed disk of pigment.
1.2There are two types of contact angles, advancing and receding. This standard deals only with advancing contact angles.
1.3This practice is intended to supplement the manufacturer’s instructions for the device being used to make the measurements, but is not intended to replace them.
1.4A common test liquid is water, but many other liquids such as solvents, surfactant and dispersant solutions and even liquid paints can be used.
1.5This practice is based on goniometry, which involves the observation of a sessile drop of test liquid on a solid substrate.
1.6Although contact angles are governed by surface tension, this standard cannot be used to measure surface tension directly.
