This second edition cancels and replaces the first edition (i. e. ISO 2178:1972). Specifies the method of using coating thickness instruments of the magnetic type for non-destructive measurements of the thickness. The method is applicable only for measurements on reasonably flat specimens. For non-magnetic substrates: see ISO 2361.
