Industrial liquid lubricants — ISO viscosity classification


This International Standard establishes a system of
viscosity classification for industrial liquid lubricants
and related fluids. This includes mineral oils used
as lubricants, hydraulic fluids, electrical oils and for
other applications. The usual method for kinematicviscosity determination is that specified in IS0 3104,
but this may give anomalous results when used with
non-Newtonian fluids (i.e. those whose coefficient of
viscosity varies significantly with rate of shear). For
SUCII fluids, it is therefore important to state the
particular method by which viscosity has been determined.
