Scope

This Standard specifies the basic methods and principles of scanning electron
microscope measurement of coating thickness (including organic, inorganic
and metal coatings) on flexible film substrate, standard samples and equipment,
operating methods, and data processing methods.
This Standard applies to the measurement of coating whose thickness is 10 nm
~ 0.5 mm on flexible film substrate whose thickness is not more than 3 mm.
