Beschichtungsstoffe - Gitterschnittprüfung (ISO 2409:2013)
Diese Internationale Norm legt ein Prüfverfahren zur Abschätzung des Widerstandes einer Beschichtung gegen Trennung vom Substrat fest, wenn ein bis zum Substrat durchgehendes Gitter in die Beschichtung geschnitten wird. Die nach diesem empirischen Verfahren gemessene Eigenschaft hängt, neben anderen Faktoren, von der Haftfestigkeit der Beschichtung auf der vorhergehenden Schicht oder auf dem Substrat ab. Dieses Verfahren ist jedoch nicht als Verfahren zur Messung der Haftfestigkeit anzusehen.
Wenn die Haftfestigkeit gemessen werden soll, kann das in ISO 4624 festgelegte Verfahren angewendet werden.
ANMERKUNG 1 Obwohl die Gitterschnittprüfung in erster Linie zur Anwendung im Laboratorium gedacht ist, ist sie auch als Feldprüfung geeignet.
Das festgelegte Verfahren kann entweder als Ja/Nein-Prüfung oder, wenn entsprechende Umstände gegeben sind, als Einstufungsprüfung mit sechs Stufen angewendet werden. Bei Mehrschichtsystemen kann auch die Zwischenschicht-Haftfestigkeit abgeschätzt werden.
Die Prüfung kann an fertigen Gegenständen und/oder an eigens dafür hergestellten Probeplatten durchge¬führt werden.
Obwohl das Verfahren auf Beschichtungen auf harten (Stahl) und weichen (Holz und Putz) Substraten anwendbar ist, erfordern diese unterschiedlichen Substrate eine unterschiedliche Durchführung (siehe Abschnitt 6).
Das Verfahren ist für Beschichtungen mit einer Gesamtschichtdicke über 250 µm oder für Struktur¬beschich-tungen nicht geeignet.
ANMERKUNG 2 Wenn das Verfahren auf Beschichtungen mit einer strukturierten Oberfläche angewendet wird, streuen die Ergebnisse zu stark (siehe auch ISO 16276-2).
Peintures et vernis - Essai de quadrillage (ISO 2409:2013)
L'ISO 2409:2013 spécifie une méthode d'essai pour l'évaluation de la résistance des revêtements de peinture à être séparés de leurs subjectiles lorsqu'on pratique dans le revêtement un quadrillage par incisions jusqu'au subjectile. La propriété déterminée par cette méthode empirique dépend, entre autres, de l'adhérence de la couche soit à la couche précédente, soit au subjectile. Cette méthode ne peut, cependant, être considérée comme un moyen de mesurer l'adhérence.
La méthode décrite peut être utilisée soit comme essai «tout ou rien» soit, le cas échéant, comme essai en vue d'une classification en six niveaux. Lorsqu'il est appliqué à un système multicouche, le mode opératoire permet également d'évaluer la résistance des couches individuelles du revêtement à se séparer les unes des autres.
L'essai peut être réalisé sur des objets finis et/ou sur des éprouvettes spécialement préparées.
La méthode ne convient ni aux revêtements dont l'épaisseur totale est supérieure à 250 µm, ni aux revêtements texturés.
Barve in laki - Preskus oprijema z zarezovanjem rešetke (ISO 2409:2013)
Ta mednarodni standard določa preskusne metode za ocenjevanje odpornosti barvnih premazov proti ločevanju od podlag, ko se v premaz vreže mrežast vzorec pod pravim kotom in prodre do podlage. Lastnost, ki se meri s tem empiričnim preskusnim postopkom, je med drugim odvisna od sprijemljivosti premaza s predhodnim premazom ali podlago. Vendar ta postopek ne velja za način merjenja sprijemljivosti. Kadar je potrebno merjenje sprijemljivosti, se lahko uporabi metoda, opisana v standardu ISO 4624. Opisana metoda se lahko uporabi kot preskus, ki ga je mogoče uspešno/neuspešno opraviti, ali pri ustreznih okoliščinah kot klasifikacijski preskus v šestih korakih. Ko se uporablja pri večslojnem sistemu, se lahko naredi ocena odpornosti proti ločevanju posameznih plasti premaza ene od druge. Preskusi se lahko opravijo na dokončanih objektih in/ali na posebej pripravljenih preskusnih vzorcih. Čeprav se metoda uporablja za barvo na trdih (npr. kovina) in mehkih (npr. les in mavec) podlagah, je pri različnih podlagah potreben različen preskusni postopek (gl. točko 6). Metoda ni primerna za premaze s skupno debelino nad 250 μm ali za teksturirane premaze.

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.
ISO 2409 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This fourth edition cancels and replaces the third edition (ISO 2409:2007), which has been technically
revised. The main changes are as follows:
a) the description of suitable methods for removal of loose paint have been transferred to an informative
annex as examples and, for the method using adhesive tape, the adhesive strength of the tape is no
longer specified;
b) the single-blade cutting tool originally used in the first edition (1972) of this International Standard
has been re-introduced;
c) a cutting tool used with automatic cross-cut apparatus has also been specified;
d) the pictorial standard for classification 2 has been replaced by one originally used in the first edition
(1972) and the second edition (1992) of this International Standard;
e) plastics have been added as an example of a hard substrate in 6.1.4;
f) a designation code has been introduced to indicate the test result;
g) the supplementary test conditions previously in Clause 7 have been integrated in the test report;
h) a note has been added to Subclause 3.2.1 that the apparatus (manual or motor-driven) and the type
of cutting tool used have an influence on the test result.

INTERNATIONAL STANDARD ISO 2409:2013(E)
Paints and varnishes — Cross-cut test
1 Scope
This International Standard specifies a test method for assessing the resistance of paint coatings
to separation from substrates when a right-angle lattice pattern is cut into the coating, penetrating
through to the substrate. The property determined by this empirical test procedure depends, among
other factors, on the adhesion of the coating to either the preceding coat or the substrate. This procedure
is not to be regarded, however, as a means of measuring adhesion.
[1]
Where a measurement of adhesion is required, the method described in ISO 4624 may be used.
NOTE 1 Although the test is primarily intended for use in the laboratory, the test is also suitable for field testing.
The method described may be used either as a pass/fail test or, where circumstances are appropriate,
as a six-step classification test. When applied to a multi-coat system, assessment of the resistance to
separation of individual layers of the coating from each other can be made.
The test can be carried out on finished objects and/or on specially prepared test specimens.
Although the method is applicable to paint on hard (e.g. metal) and soft (e.g. wood and plaster) substrates,
