What is EN ISO 12944-2:2019?

EN ISO 12944-2:2019 is an international standard that provides guidelines for the corrosion protection of steel structures through paint systems. It is part of a series of standards developed by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN) to ensure effective and long-lasting corrosion protection.

The Importance of Corrosion Protection

Corrosion is a natural process that occurs when metals react with their environment. It can weaken structures, reduce their lifespan, and increase maintenance costs. Therefore, it is crucial to protect steel structures from corrosion to ensure their durability and safety.

EN ISO 12944-2:2019 aims to provide guidance on selecting suitable paint systems based on the corrosive environment in which the steel structure is exposed. It takes into account factors such as temperature, humidity, chemical exposure, and abrasion resistance.

Main Requirements of EN ISO 12944-2:2019

The standard outlines four main elements for achieving effective corrosion protection:

Surface Preparation: Proper cleaning and removal of contaminants (e.g., rust, grease, and dirt) is essential before applying paint systems. This ensures good adhesion and performance of the coating.

Paint Systems: The standard specifies different types of coating systems, consisting of primers, intermediate coats, and topcoats. Each layer has specific functions, such as corrosion inhibition, mechanical strength, and aesthetic appeal.

Application Process: EN ISO 12944-2:2019 provides recommendations for the application of paint systems, including methods, equipment, and environmental conditions. Proper application ensures uniform coating thickness and adequate coverage.

Maintenance: Regular inspection and maintenance are necessary to ensure the long-term effectiveness of the paint system. This involves identifying damaged or deteriorated areas and taking appropriate repair actions.

Benefits of EN ISO 12944-2:2019

Adhering to the guidelines outlined in EN ISO 12944-2:2019 offers several benefits:

Enhanced Durability: The standard helps to select suitable paint systems that provide long-term corrosion protection, extending the lifespan of steel structures.

Cost Savings: Effective corrosion protection reduces maintenance and repair costs associated with structural damage due to corrosion.

Improved Safety: Corrosion weakens steel structures, compromising their integrity. Following the standard safeguards against potential accidents or failures.

Environmental Considerations: EN ISO 12944-2:2019 promotes the use of environmentally friendly coatings that have minimal impact on the ecosystem.
