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).

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);

no exposure to fluids; Grade 1:
sporadic exposure to droplets of fluid (e.g. laboratory floors, floors in small units, walls); Grade 2: frequent, short-term exposure to splashes of fluid, where the surfaces are regularly flushed (e.g. floors of closed production plants); Grade 3: exceptional and limited exposure to fluids during operations (e.g. due to plant failure) in, for example, secondary containment; Grade 4: constant or frequent exposure to a film of fluid, due to wetness, condensation, puddles, trickles and the like (e.g. floors in production plants, electroplating plants or pumping stations); Grade 5: operational exposure to a constant flow of fluid involving no significant hydrostatic pressure (e.g. open gutters, trenches and their pump sumps, closed trenches and pipes); Grade 6: constant exposure of containers to fluid contents for unlimited periods (e.g. vessels, pits). 4.2.4 Thermal loading The thermal load caused by medium effect or other sources of heat affects the effectiveness of a surface protection system in the following way: a) Aggressiveness of medium Elevated temperatures increase the aggressiveness of the medium by raising the levels of its chemical reactions and diffusion, and also through the accumulation of volatile substances in the headspace. b) Thermal stress Temperatures which deviate from the installation temperature cause thermal stress between the substrate and the surface protection system and may cause peeling, cracks etc. This may result from the direct action of hot or cold media, or from radiant heat and extreme ambient temperature. The maximum thermal load shall be stated in °C. 4.2.5 Changes in temperature Changes in temperature include: a) temperature changes at the protective surface during exposure to fluid loads of grades 3 to 5 as in 4.2.3 caused by increased/decreased medium temperatures; b) temperature changes as otherwise constantly heated or cooled surfaces, resulting from operational circumstances, such as start-up and shutdown; c) temperature changes, possibly involving thermal shock, which occur during cleaning operations; d) process-related changes in the temperature of the medium under loading conditions corresponding to grade 6 (as in 4.2.3). Temperature changes due to climatic influences are dealt with in 4.2.7.

no temperature changes; Grade 1:
infrequent temperature changes up to 50 K; Grade 2:
infrequent temperature changes of more than 50 K; Grade 3:
frequent temperature changes up to 50 K; Grade 4:
frequent temperature changes of more than 50 K. Grade 5:
temperature changes involving thermal shock. 4.2.6 Mechanical loading The effectiveness of a surface protection system may be impaired through exposure to mechanical loads or hydrostatic pressure during operation or assembly. The following grades shall be used to assess such loads. Grade 0:
no loads, or hydrostatic pressure up to 0,05 bar; Grade 1:
loads up to 0,2 N/mm2 (e.g. pedestrian traffic, light transport, static loading); Grade 2:
loads up to 1 N/mm2 (e.g. vehicles with pneumatic tires, static loading); Grade 3:
loads over 1 N/mm², for example
a) loads of 1 N/mm2 to 7 N/mm2 (e.g. vehicles with Vulkollan wheels, static loading);
b) loads over 7 N/mm2 (e.g. vehicles with polyamide wheels, static loading); Grade 4:
impact loads, such as those resulting from setting down sharp-edged objects (e.g. barrels), and from scraping (e.g. shovel loaders); Grade 5:
hydrostatic pressure from 0,05 bar to 0,5 bar; Grade 6:
hydrostatic pressure greater than 0,5 bar. 4.2.7 Weather factors Climatic influences may affect the durability of a surface protection system, and shall be graded as follows: Grade 0:
no climatic influences: the component is located inside a building and is not exposed to climatic influences; Grade 1:
limited climatic influences: a roof protects the component, which is exposed to limited climatic influences; Grade 2:
full climatic influences: the component is located outside, and is fully exposed to climatic influences.

Because of the wide variety of possibilities, combinations of these coatings are not included in this table.
5.3.2 Properties of coatings The properties of coatings shall be subject to agreement and Annex A may serve as form. Guideline values for the thickness of individual coats or layers are given in Table 4. The table gives approximate values. The thickness value of each coat shall be in accordance with the manufacturer's instructions. Coats or layers shall be compatible with each other and adhere properly. In order to improve the non-skid property of the coating, fine granules (sand or other fine-grained aggregates) may be spread on the fresh sealing coat, and a further sealing coat subsequently applied. If dissipation capability of electrostatic charges is required, at least the upper coat shall be conductive.

5.3.3 Impregnating agents Impregnating agents are low-viscosity, easily absorbed resins or resin solutions used to saturate the pores in screed or concrete substrates. They are designed to harden the floors of industrial buildings, increase their wear resistance and limit the effects of abrasion, such as dust build-up. 5.3.4 Primers Primers are designed to seal the pores of the concrete substrate and provide a key for the coating. They consist of low-viscosity substances, which may be solvent-borne, and may be based on a different binder than that used in subsequent coats. Care should be taken that solvents contained in the priming coat have fully evaporated before the subsequent coating is applied. Depending on the coating system, the priming coat may be applied in one or more layers, quartz sand being spread over the fresh coating to form a key for the next coat or layer. If an intermediate layer is applied to the entire surface, a priming coat can be omitted. Bitumen first coats or heat resistant epoxy resins are used as primers for mastic asphalt screed. 5.3.5 Intermediate layers Intermediate layers are used to fill and to even out inevitable surface irregularities (flash, cavities and pinholes). In case of furane and/or phenol formaldehyde resin coatings, the fully cured intermediate layer shall inhibit the chemical reaction between the concrete substrate and the acid hardener. Intermediate layers may be based on a different resin than that used for subsequent coats.
