TS EN 14879-1

TS EN 14879-1 addresses the terminology, design principles, and substrate preparation for organic coating systems and linings used to protect industrial apparatus and plants against corrosion caused by aggressive media. It is aimed at equipment used in chemical production and handling, and it applies to both metallic and concrete structures.

In general technical terms, organic coatings and linings act as a barrier between the aggressive medium and the underlying structure. In this series, protection is considered in two directions: safeguarding the apparatus from corrosion and helping prevent contamination of the media being processed or stored. That dual perspective is especially relevant for reactors, storage tanks, and industrial floors exposed to continuous contact, splash, or vapour-related attack.

What the standard distinguishes

• It is focused on protection systems for aggressive media exposure, not atmospheric corrosion protection.
• It covers thick coatings, normally 1 mm or more in thickness.
• It includes linings made from prefabricated sheet or plate materials.
• It also covers combined linings using tile and brick layers.
• It addresses the design and substrate-preparation principles for metallic and concrete substrates.

So, this standard is best understood as a framework for defining and preparing corrosion-protection systems rather than a product specification for one coating type. In practice, the performance of such systems depends on matching the lining concept to the chemical environment, the substrate condition, and the intended service conditions.
