Organic coating systems and linings for protection of industrial apparatus and plants against corrosion caused by aggressive media - Part 3: Coatings on concrete components
This European Standard specifies the requirements for and methods of testing of organic coatings which are applied to concrete process engineering equipment that will come in contact with aggressive 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).
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 damaging effects of aggressive substances;
- to protect waters (e.g. ground water) from harmful substances;
- to protect the charge from becoming contaminated by components released from the substrate material;
- to achieve a particular surface properties.
The different coating systems are:
a) impregnation, seals, thin coatings (applied by brushing, spraying or rolling);
b) high-build coatings (applied by brushing, spraying, rolling, trowelling or pouring (self-levelling));
c) laminate coatings;
d) resinous screed;
e) mastic asphalt screed with a waterproofing layer;
f) combinations of the above coatings.
Table 1 shows the coating methods to be employed for various types of concrete members.
Handling of aggressive or water pollutant materials is understood to include:
storage;
1) filling;
2) loading and unloading;
3) manufacture;
4) treatment;
5) use.

Diese Europäische Norm legt die Anforderungen und Prüfverfahren für Beschichtungen aus organischen
Werkstoffen für Bauteile aus Beton 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).
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 verschiedenen Oberflächenschutzsysteme sind:
a) Imprägnierungen, Versiegelungen und Dünnbeschichtungen (als Streich-, Spritz- oder Rollbeschichtungen);
b) Dickbeschichtungen (als Streich-, Spritz-, Rollbeschichtungen, Spachtelbeschichtungen oder Verlaufbeschichtungen;
c) Laminatbeschichtungen;
d) Kunstharzestriche;
e) Gussasphaltestriche im Verbund mit einer Dichtschicht;
f) Kombinationen aus obigen Beschichtungen.
Tabelle 1 enthält die für verschiedene Arten von Betonbauteilen anzuwendenden Beschichtungsverfahren.
Der Umgang mit aggressiven oder wassergefährdenden Stoffen umfasst das
a) Lagern
b) Abfüllen
c) Umschlagen
d) Herstellen
e) Behandeln
f) Verwenden.

For the scope or this European Standard, the stress types detailed in 4.2.2 to 4.2.8 are the most relevant. Where necessary, grades have been used to describe different levels of stress. 4.2.2 Exposing media Aggressive substances or water pollutants may occur as solids, fluids or gases. Their aggressive action on concrete usually occurs when they are in a liquid state (e.g. aqueous solutions or condensates). The substances may exist in their pure state, or as mixtures and may occur in different intervals. These substances shall be designated using the Geneva nomenclature, IUPAC1) nomenclature or CAS2) number. They may also be designated by trivial names which have become established in the literature. Concentrations and any changes to these shall be given as a percentage by mass or volume, or as g/l, g/kg, mol/l etc. The pH value shall also be given for aqueous solutions. All constituents, including traces and impurities, shall be named, even if they do not attack concrete. Successive exposur
