Scope

This Standard specifies the principle, significance and use, apparatus, reagents and
materials, calibration and standardization, test procedure, calculations and report of
the determination of dynamic surface tension using chemicals by fast-bubble
technique.
This Standard is applicable to the determination of the specific free energy of a liquid-
gas surface a short time after formation of the surface.
This Standard is applicable to liquids with vapor pressures up to 30.0 kPa and
kinematic viscosities up to 4.0 mm/s at the test temperature.
NOTE. Higher viscosities have not yet been investigated.
