This International Standard describes the application of the Vickers and Knoop micro-indentation tests for
determining the microhardness of metallic and other inorganic coatings. This method is applicable where indenter
forces generally need to be below 10 N such as for electrodeposited coatings, autocatalytic coatings, sprayed
coatings and anodic coatings on aluminium. It is applicable to measurements normal to the coated surface as
described in 7.4 and to measurements on cross-sections as described in 7.3.
NOTE 1 Attention is drawn to ISO 4545, ISO 6507-1, ISO 6507-2 and ISO 6507-3, which describe Knoop and Vickers
hardness testing of metallic materials. Other International Standards for instrumental indentation testing, the verification of
microindentation testing instruments and for the verification of reference blocks to be used with such instruments are currently
being developed (e.g. ISO 14577 Parts 1 to 4).
NOTE 2 Usually for hardness measurements of coating test forces in the microhardness range in accordance with
ISO 6507-1 are used. However, since the largest possible test force should be selected, test forces of the low force and
hardness ranges may also be used.
Diese ÖNORM beschreibt die Mikrohärteprüfung für elektrolytisch oder autokatalytisch abgeschiedene Schichten, für aufgespritzte Schichten sowie für anodisch erzeugte Oxidschichten auf Aluminium, bei der die Kräfte auf den Eindringkörper im allgemeinen weniger als 10 N betragen. Nach diesem Verfahren sind Messungen normal zur beschichteten Oberfläche für Schichtdicken von mindestens 15 µm und Messungen an Querschliffen durchführbar.
