What is BS EN 14879-3 – Organic coatings on concrete components about?
EN 14879 series is a European Standard that discusses organic coating systems and linings. The purpose of BS EN 14879 is to provide best industry requirements of organic coating systems and lining to ensure the components they are applied on are adequately protected from corrosion and overall deterioration.
BS EN 14879-3 is the third part of the EN 14879 series that specifies the requirements for and methods of testing 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 different coating systems are:
- Impregnation, seals, thin coatings (applied by brushing, spraying or rolling)
- High-build coatings (applied by brushing, spraying, rolling, trowelling or pouring (self-levelling)
- Laminate coatings
- Resinous screed
- Mastic asphalt screed with a waterproofing layer
- Combinations of the above coatings
Handling of aggressive or water pollutant materials is understood to include:
- Storage
- Filling
- Loading and unloading
- Manufacture
- Treatment
- Use
Note: BS EN 14879-3 does not cover coatings as in EN ISO 12944-1, but it does apply to coatings that serve one or more of the following purposes:
- To protect the component from the damaging effects of aggressive substances
- To protect waters (e.g. groundwater) from harmful substances
- To protect the charge from becoming contaminated by components released from the substrate material
- To achieve a particular surface properties
Who is BS EN 14879-3 - Organic coatings on concrete components for?
BS EN 14879-3 on organic coatings on concrete components is useful for:
- The construction industry
- Coating manufacturers
- Civil engineering equipment manufacturers
- Designers of structural elements
- Quality control and testing personnel
- Civil engineers
Why should you use BS EN 14879-3 - Organic coatings on concrete components?
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. Thus, it is important to assess the effect of aggressive chemical substances on the organic coatings of concrete components to maintain the structural and functional integrity of your civil engineering works.
BS EN 14879-3 provides guidance on protective coatings for various types of concrete structures for better selection, suitability verification, and tests requirements of coatings on concrete components to demonstrate their durability and resistance to aggressive chemical substances.
BS EN 14879-3 can thus ensure your organic coatings are of high quality that help eliminate the effects of corrosion caused by aggressive media. This can ultimately build reliability and credibility for your products and business.
