ISO International Standard

ISO 27307:2015 specifies a method for adhesion and cohesion evaluation of thermal sprayed ceramic coating-substrate systems by means of a transverse scratch test. This International Standard is suitable for thermal sprayed ceramic coatings with thickness from 50 μm to over 1 000 μm. It is also suitable for testing ceramic coatings deposited by other spray coating processes, such as cold spray, as well as aerosol deposition.
