What is EN ISO 12944-2: 2019 ?

EN ISO 12944-2: 2019 is an essential international standard that provides guidelines for the corrosion protection of steel structures. It is specifically designed to help engineers, architects, and professionals understand and implement effective corrosion protection measures for steel structures in both industrial and non-industrial environments.

The primary purpose of EN ISO 12944-1: 2017 is to offer a comprehensive approach to protecting steel structures from corrosion. The standard outlines various methods of surface preparation, types of protective coatings, and application procedures to ensure the longevity and durability of steel structures.

EN ISO 12944-2: 2019 helps engineers and professionals to understand and classify the different environments in which steel structures are used. The standard defines four types of corrosivity categories based on the level of threat, ranging from C1 (very low corrosivity) to C5 (very high corrosivity). Each category requires a specific approach to surface preparation and protective coating systems to ensure long-term durability of steel structures.

Surface preparation and protective paint systems are critical components of the corrosion protection process. The standard provides guidelines for surface preparation, including the removal of dirt, grease, rust, and other contaminants, to ensure a clean and smooth surface for application of protective coatings.

The standard also outlines the different types of protective coatings that can be used, such as epoxy coatings, polyurethane coatings, and metal-based coatings. Each type of coating is recommended for specific corrosivity categories and provides specific requirements for application, including the thickness and coverage of the coating.

Conclusion

In conclusion, EN ISO 12944-2: 2019 is an important international standard that provides guidelines for the corrosion protection of steel structures. The standard defines four types of corrosivity categories based on the level of threat and outlines various methods of surface preparation and protective coating systems to ensure the longevity and durability of steel structures. Understanding this standard is crucial for professionals involved in corrosion protection and ensuring the safety and reliability of steel structures in various environments
