This Standard specifies a method for determining the measurement of dry film thickness of coating films by microscopic observation of a precision-cut shallow-angle crater in the coating film.
The substrate may be any rigid, metallic material, for example, cold-rolled steel, hot-dip galvanized steel, aluminium, etc. The substrate should be planar.
Variations in the surface profile of the substrate may result in non-representative organic coating thickness readings. This condition may exist over substrates such as hot-dip, coated steel sheet. This is true of all precision cut methods that are used to determine dry film thickness of organic coatings.
This method is only valid for coating thicknesses between 0 to 90 µm, for measurements of films greater than 90 µm but less than 1575 µm, a 45° borer may be used in accordance with this test method.
