Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of the abrasion resistance of coatings by a micro-scale abrasion test (ISO 26424:2008)
ISO 26424:2008 specifies a method for measuring the abrasive wear rate of ceramic coatings by means of a micro-scale abrasion wear test based on the well-known crater-grinding technique used for coating thickness determination in ISO 26423.
The method can provide data on both coating and substrate wear rates, either by performing two separate tests or by careful analysis of the data from a single test series.
The method can be applied to samples with planar or non-planar surfaces, but the results analysis described in the text applies only to flat samples. For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
Hochleistungskeramik - Bestimmung der Beständigkeit gegen Abrieb von Schichten durch eine Mikroabriebprüfung (ISO 26424:2008)
Diese Internationale Norm legt ein Verfahren zur Messung der Abriebverschleißrate keramischer Schichten mithilfe einer Mikroabriebprüfung fest, die auf dem bekannten Kalottenschleifverfahren zur Bestimmung der Schichtdicke nach ISO 26423 [11] basiert.
Nach diesem Verfahren können Daten zur Bestimmung der Abriebverschleißraten sowohl der Schicht als auch des Grundwerkstoffes ermittelt werden, entweder durch zwei separate Prüfungen oder aber durch eine sorgfältige Analyse der aus einer einzigen Prüfserie gewonnenen Daten.
Das Prüfverfahren kann bei Proben mit ebenen oder nicht ebenen Oberflächen angewendet werden, während die in Abschnitt 9 beschriebene Auswertung nur für ebene Proben gilt. Bei nicht ebenen Proben ist eine komplexere Auswertung erforderlich, möglicherweise mithilfe numerischer Verfahren.
Céramiques techniques - Détermination de la résistance à l'abrasion des revêtements par essai d'abrasion à micro-échelle (ISO 26424:2008)
L'ISO 26424:2008 traite d'une méthode permettant de mesurer le taux d'usure par abrasion des revêtements céramiques au moyen d'un essai de micro-usure par abrasion basé sur la technique bien connue d'abrasion d'une calotte sphérique utilisée pour déterminer l'épaisseur du revêtement dans l'ISO 26423 [11].
Cette méthode permet d'obtenir des données relatives aux taux d'usure du revêtement et du substrat, que ce soit en réalisant deux types d'essai différents ou en analysant minutieusement les données issues d'une série d'essais d'un seul type.
Cette méthode peut s'appliquer aux échantillons disposant de surfaces planes ou non planes, mais l'analyse des résultats décrite à l'Article 9 ne peut être utilisée que pour les échantillons plats. En ce qui concerne les échantillons non plats, il y a lieu de procéder à une analyse plus complexe, nécessitant éventuellement l'application de méthodes numériques.
Fina keramika (sodobna keramika, sodobna tehnična keramika) - Ugotavljanje odpornosti prevlek proti obrabi z mikroabrazivnim preskusom (ISO 26424:2008)
Ta mednarodni standard določa metodo za merjenje stopnje abrazivne obrabe keramičnih prevlek z mikroabrazivnim preskusom na podlagi uveljavljene tehnike čelnega brušenja, ki se uporablja za ugotavljanje debeline prevleke v standardu ISO 26423[11]. Metoda lahko zagotovi podatke o stopnji obrabe prevleke in substrata, tako da se izvedeta dva ločena preskusa, ali s skrbno analizo podatkov iz enega preskusnega niza. Metodo je mogoče uporabiti za vzorce z ravnimi ali neravnimi površinami, vendar pa se rezultati analize, opisani v točki 9, uporabljajo samo za ploske vzorce. Pri neravnih vzorcih je potrebna bolj zapletena analiza, ki morda zahteva uporabo številskih metod.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

INTERNATIONAL STANDARD ISO 26424:2008(E)
Fine ceramics (advanced ceramics, advanced technical
ceramics) — Determination of the abrasion resistance of
coatings by a micro-scale abrasion test
1 Scope
This International Standard specifies a method for measuring the abrasive wear rate of ceramic coatings by
means of a micro-scale abrasion wear test based on the well-known crater-grinding technique used for
[11]
coating thickness determination in ISO 26423 .
The method can provide data on both coating and substrate wear rates, either by performing two separate
tests or by careful analysis of the data from a single test series.
The method can be applied to samples with planar or non-planar surfaces, but the results analysis described
in Clause 9 applies only to flat samples. For non-planar samples, a more complicated analysis, possibly
requiring the use of numerical methods, is required.
