Paints and varnishes - Determination of resistance to cyclic corrosion conditions - Part 3: Testing of coating systems on materials and components in automotive construction (ISO 11997-3:2022)
This document specifies a method based on a cyclic corrosion test for testing the corrosion protection of automobiles using coating systems on aluminium, steel or galvanized steel.
The test method uses corrosive conditions (temperature and humidity ramps and salt spray) to create realistic corrosion patterns. These corrosion patterns are typical for automobiles, and they are comparable in the case of sufficiently similar protective coating systems. In particular, the accelerated test investigates the delamination/corrosion creep that results from defined artificial damage to a coating. Investigations of surface and edge corrosion or investigations of adhesive specimens or components are also covered. This cyclic corrosion test is also suitable for testing corrosion in flanged areas or near gaps.
This document was developed for the assessment of coated substrates (test specimens, bodywork and mounted parts) in the automotive industry. Other applications, such as components with unpainted metallic coatings, were not part of the scope of the standardization work. This document was originally developed for coating systems on aluminium, steel or galvanized steel but it can also be used for the assessment of the corrosion resistance of coating systems on other metals and their alloys.
Beschichtungsstoffe - Bestimmung der Beständigkeit bei zyklischen Korrosionsbedingungen - Teil 3: Prüfung von Beschichtungssystemen auf Werkstoffen und Bauteilen im Automobilbau (ISO 11997-3:2022)
Dieses Dokument legt ein Verfahren zum Prüfen des Korrosionsschutzes von Automobilen durch Beschichtungssysteme auf Aluminium, Stahl oder verzinktem Stahl mittels eines Korrosionswechseltests fest.
Bei dem Prüfverfahren werden unter korrosiven Bedingungen (Temperatur- und Feuchterampen, Salznebel) realistische Korrosionsbilder erzeugt. Diese Korrosionsbilder sind automobiltypisch und bei hinreichend ähnlichen Korrosionsschutzsystemen vergleichbar. Die Kurzprüfung bildet insbesondere die von einer definiert angebrachten Beschichtungsverletzung ausgehende Enthaftung/Unterwanderung ab. Die Untersuchung der Flächen- und Kantenkorrosion sowie von Klebeproben oder Bauteilen wird ebenfalls beschrieben. Dieser Korrosionswechseltest ist auch für die Prüfung der Korrosion in Flansch- und Spaltbereichen geeignet.
Dieses Dokument wurde für die Beurteilung von beschichteten Substraten (Probenkörper, Karosserien und Anbauteilen) der Automobilindustrie entwickelt. Andere Anwendungen, wie z. B. Bauteile mit unlackierten Metallbeschichtungen, waren bei der Normungsarbeit nicht Teil des Anwendungsbereiches. Dieses Dokument wurde ursprünglich für Beschichtungssysteme auf Aluminium, Stahl oder verzinktem Stahl entwickelt, kann aber auch für die Bewertung der Korrosionsbeständigkeit von Beschichtungssystemen auf anderen Metallen und deren Legierungen verwendet werden.
Peintures et vernis - Détermination de la résistance aux conditions cycliques de corrosion - Partie 3: Essais de systèmes de revêtements sur matériaux et composants en construction automobile (ISO 11997-3:2022)
Le présent document spécifie une méthode fondée sur un essai de corrosion cyclique permettant d’évaluer la protection contre la corrosion fournie par des systèmes de revêtements appliqués sur l’aluminium, l’acier ou l’acier galvanisé dans l’industrie automobile.
Les conditions de corrosion (rampes de température et d’humidité et brouillard salin) mises en œuvre dans la méthode d'essai sont destinées à obtenir des modèles de corrosion réalistes. Ces modèles de corrosion sont caractéristiques de l’industrie automobile et peuvent être comparés les uns aux autres lorsque les systèmes de revêtements protecteurs se ressemblent suffisamment. En particulier, l’essai accéléré étudie le décollement/fluage dû à la corrosion résultant de dommages artificiels déterminés causés à un revêtement. Sont également étudiés la corrosion de surface et la corrosion des arêtes, ainsi que les éprouvettes ou pièces adhésives. Cet essai de corrosion cyclique convient également pour évaluer la corrosion dans les zones comportant des brides ou à proximité des entrefers.
Le présent document a été élaboré pour l’évaluation des subjectiles revêtus (éprouvettes d’essai, carrosserie et pièces montées) dans l’industrie automobile. D’autres applications (par exemple celles qui utilisent des pièces pourvues de revêtements métalliques non peints) n’entrent pas dans le domaine d’application du travail de normalisation. Le présent document a été élaboré, à l’origine, pour des systèmes de revêtements sur aluminium, acier ou acier galvanisé; il peut toutefois être utilisé également pour évaluer la résistance à la corrosion de systèmes de revêtements sur d’autres métaux et leurs alliages.
Barve in laki - Ugotavljanje odpornosti proti cikličnim korozijskim pogojem - 3. del: Preskušanje premaznih sistemov na materialih in sestavnih delih v avtomobilski industriji (ISO 11997-3:2022)
Ta dokument določa metodo za preskušanje protikorozijske zaščite avtomobilov z uporabo premaznih sistemov na aluminiju, jeklu ali pocinkanem jeklu, ki temelji na preskusu ciklične korozije.
S preskusno metodo se v korozivnih pogojih (povečanje temperature in vlažnosti ter slana megla) ustvarijo realistični korozijski vzorci. Ti korozijski vzorci so značilni za avtomobile in so primerljivi, če so si zaščitni premazni sistemi zadosti podobni. S pospešenim preskusom se zlasti ugotavlja razslojitev/korozijsko lezenje, ki je posledica opredeljene umetne poškodbe premaza. Zajeto je tudi preiskovanje površinske korozije in korozije robov oziroma lepilnih vzorcev ali sestavnih delov. Ta preskus ciklične korozije je primeren tudi za preskušanje korozije na delih s prirobnicami ali v bližini rež.
Dokument je bil pripravljen za ocenjevanje podlag s premazom (preskušancev, karoserije in vgrajenih delov) v avtomobilski industriji. Druge vrste uporabe, kot so sestavni deli z nebarvanim kovinskim premazom, niso bile zajete v standardizacijskem delu. Dokument je bil prvotno pripravljen za premazne sisteme na aluminiju, jeklu ali pocinkanem jeklu, vendar ga je mogoče uporabiti tudi za ocenjevanje odpornosti premaznih sistemov na drugih kovinah in njihovih zlitinah proti koroziji.
