Abstract

The requirements for the quality of protection on metal structures in terms of durability, reliability and efficiency require from the manufacturer to define certain procedures and verification of anticorrosion protection activities. Today, the criteria used to evaluate the success of the protection and the general quality of the structure are the criteria listed in the EN 1090 standard and in the compatible standards related to the realization and protection of metal structures. The article briefly describes the basis of the requirements of the standard, the eligibility criteria for the protection of structures and it also gives a practical example of the verification process through preparation, implementation and control.

Highlights

  • The quality of protection on metal structures in terms of durability, reliability and efficiency and the verification of anticorrosion protection activities are widely studied in scientific papers

  • Thereby, different coatings are researched, such as the polyetheramide (PEtA) coatings on carbon steel in [1], ecologically acceptable waterborne and multi-layered coatings in [2], or different super-hydrophobic coating systems obtained by different preparation technologies in [3]

  • The application of the EN 1090 standard is related to the requirements for the conformity assessment of structural components for the construction of steel structures and it covers all constituent parts or elements that can have an important impact on the construction

Summary

INTRODUCTION

The quality of protection on metal structures in terms of durability, reliability and efficiency and the verification of anticorrosion protection activities are widely studied in scientific papers. The anti-graffiti properties of a polyurethane organic coating are studied in [5], while the protection of buried metallic structures against corrosion by using coatings combined with cathodic protection is researched in [6]. At the beginning of this research, the assumption was that the internal quality verification of coatings on structure materials depends mostly on the characteristics of the coating quality, surface preparation and application technology. These factors are essential for the compliance with the requirements of the EN 1090 and the related norms. The most important conclusions are given at the end of the paper
