Organic coating systems and linings for protection of industrial apparatus and plants against corrosion caused by aggressive media - Part 2: Coatings on metallic components

This European Standard specifies the requirements for and methods of testing of organic coatings which are applied to metallic process engineering equipment that will come in contact with chemical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of quality control (e.g. as agreed between the contract partners or been given by national regulations).
The standard does not cover coatings as in EN ISO 12944-1, but it does apply to coatings which serve one or more of the following purposes:
-   to protect the component from adverse effects of aggressive substances;
-   to protect waters (e.g. ground water) against hazardous substances;
-   to protect the charge from becoming contaminated by components released from the substrate material;
-   to achieve a particular surface properties.
The described coatings are to be used for metallic process engineering equipment that will come in contact with chemical substances. The different coating systems are:
-   laminate coating systems which contain cold-curing resins;
-   trowelled coating which contain cold-curing resins;
-   sprayed coating systems which contain resins (in special cases, such coatings may also be applied by brushing, rolling, flow coating, dipping, or by other means, such as providing sleeving for nozzles);
-   powder coating systems which contain organic materials (powder coatings may be used as corrosion protection or for non-stick purposes).
For design and preparation of substrate see EN 14879-1.

Beschichtungen und Auskleidungen aus organischen Werkstoffen zum Schutz von industriellen Anlagen gegen Korrosion durch aggressive Medien - Teil 2: Beschichtungen für Bauteile aus metallischen Werkstoffen

Diese Europäische Norm legt die Anforderungen und Prüfverfahren für Beschichtungen aus organischen
Werkstoffen für metallische Bauteile in verfahrenstechnischen Anlagen fest, die mit chemischen Substanzen
(Flüssigkeiten, Feststoffen und Gasen) in Berührung kommen. Die in dieser Norm festgelegten Anforderungen
können für die Qualitätslenkung zugrunde gelegt werden (z. B. nach Vereinbarung zwischen den Vertragspartnern
oder nach den Vorgaben durch nationale Regelungen).
Die vorliegende Norm gilt nicht für Beschichtungen nach EN ISO 12944-1, sie gilt jedoch für Beschichtungen
für eine oder mehrere der folgenden Verwendungszwecke:
- Schutz des Bauteils vor schädlichen Einwirkungen durch aggressive Stoffe;
- Schutz der Gewässer (z. B. Grundwasser) vor schädlichen Stoffen;
- Schutz des Füllgutes vor Verunreinigung durch lösliche Bestandteile im Trägerwerkstoff;
- Erzielung einer besonderen Oberflächenbeschaffenheit.
Die beschriebenen Beschichtungen sind für Bauteile aus metallischen Werkstoffen in verfahrenstechnischen
Anlagen zu verwenden, die mit chemischen Substanzen in Berührung kommen. Die verschiedenen Oberflächenschutzsysteme
sind:
- Laminatbeschichtungen mit kalthärtenden Harzen;
- Spachtelbeschichtungen mit kalthärtenden Harzen;
- Spritzbeschichtungen mit Harzen (in Sonderfällen können diese Beschichtungen auch durch Streichen,
Rollen, Fluten, Tauchen, oder andere Maßnahmen, wie z. B. Einsatz vorgefertigter Hülsen, erfolgen);
- Pulver-Beschichtungen mit organischen Werkstoffen (Pulverbeschichtungen können als Korrosionsschutz
oder Antihaftbeschichtung verwendet werden);
Konstruktion und Vorbereitung des Untergrundes, siehe EN 14879-1.

Systemes de revetements organiques de peinture et autres revetements rapportés pour la protection des appareils et installations industriels contre la corrosion par des milieux agressifs - Partie 2: Revetements pour composants métalliques

Le présent document décrit les exigences et méthodes d'essai pour revetements organiques appliqués sur des équipements de l’industrie qui seront en contact avec des substances chimiques (liquides, solides et gazeuses). Les exigences spécifiées ici peuvent etre utilisées aux fins de contrôle qualité (comme convenu entre des contractants ou imposées par des réglementations nationales, par exemple).
La norme ne concerne pas les revetements faisant l'objet de l'EN ISO 12944-1, mais s'applique aux revetements employées a l’une au moins des utilisations suivantes :
-   protéger le composant contre les effets néfastes des substances corrosives ;
-   protéger les eaux (par exemple, les nappes phréatiques) des substances dangereuses ;
-   empecher toute contamination des fluides par des composés provenant des subjectiles ;
-   obtenir une qualité de surface spécifique.
Les revetements décrits dans le présent document doivent etre utilisés pour des équipements métalliques de l’industrie chimique, entrant au contact de substances chimiques. Les différents systemes de revetements sont les suivants :
-   systemes de revetements stratifiés, contenant des résines a durcissement a froid ;
-   revetement a la truelle, contenant des résines a durcissement a froid ;
-   systemes de revetements appliqués par pulvérisation, contenant des résines (dans certains cas particuliers, des revetements de ce type peuvent également etre appliqués a la brosse, au rouleau, par aspersion, par trempage ou par d'autres moyens, tels que, par exemple, les buses) ;
-   systemes de revetements pulvérulents, contenant des matériaux organiques (les revetements  pulvérulents peuvent  servir de protection contre la corrosion ou d’anti-adhésion).
Pour la conception et la préparation des subjectiles, voir l’EN 14879-1.

Selection criteria 4.1.1 General The stress to be encountered by a protective coating shall be known before the requirements for it can be specified. For the scope of this European Standard, the stress types detailed in 4.1.2 to 4.1.8 are the most relevant. Where necessary, grades have been used to describe different levels of stress. 4.1.2 Exposing media Aggressive substances or water pollutants may occur as solids, fluids or gases. Their aggressive action on metallic components usually occurs when they are in a liquid state (e.g. aqueous solutions or condensates). The substances may occur at varying intervals in their pure state or as mixtures.
