What is EN ISO 12944-7:2018

EN ISO 12944-7:2018 is an international standard that provides guidelines and recommendations for the protective painting of steel structures against corrosion. It is part of the EN ISO 12944 series of standards, which cover various aspects of corrosion protection for steel structures. In this article, we will explore the key features and requirements of EN ISO 12944-7:2018 in a simple and easy-to-understand manner.

Scope of EN ISO 12944-7:2018

EN ISO 12944-7:2018 focuses on the specific requirements for the execution and supervision of paint work. It applies to the preparation of surfaces, the selection and application of paint systems, and the quality control measures necessary for ensuring effective corrosion protection. The standard is applicable to both new structures and those undergoing maintenance or repair work.

Key Elements of EN ISO 12944-7:2018

The standard emphasizes the importance of surface preparation before paint application. It provides detailed guidelines on cleaning methods, such as mechanical cleaning, solvent cleaning, and water jetting. Proper surface preparation is critical for achieving good adhesion and long-lasting corrosion protection.

EN ISO 12944-7:2018 also covers the selection of paint systems based on the corrosivity category of the environment. Different environmental conditions require different levels of protection, and the standard provides clear guidance on the thickness and number of paint layers required for each category.

Ensuring Quality Control

EN ISO 12944-7:2018 highlights the importance of quality control throughout the painting process. It specifies the qualifications and responsibilities of personnel involved in paint application and inspection. The standard also outlines the requirements for monitoring and documenting key parameters, such as surface preparation, paint thickness, and curing conditions.

Regular inspections and maintenance are crucial to ensure the ongoing effectiveness of the corrosion protection system. EN ISO 12944-7:2018 provides guidance on the frequency and extent of inspections needed, as well as the necessary corrective actions in case of damage or deterioration.

In conclusion, EN ISO 12944-7:2018 is an essential standard for the protective painting of steel structures against corrosion. By following its guidelines and recommendations, engineers, contractors, and inspectors can ensure the durability and reliability of painted steel structures in various environmental conditions.
