Overview
EN ISO 17834:2003 is a European and international standard developed by CEN and ISO, focusing on thermal spraying coatings designed for protection against corrosion and oxidation at elevated temperatures-up to 1000°C (1273 K). This standard specifies the requirements for sprayed metal coatings applied primarily on iron and steel, to enhance their durability and performance in high-temperature environments. It excludes coatings like sprayed aluminium and zinc for atmospheric corrosion, which are covered under ISO 2063.
The standard covers material selection, application processes, coating characteristics, and appropriate subsequent treatments, ensuring uniform protection and long service life in demanding industrial conditions.
Key Topics
Applications
EN ISO 17834:2003 is essential for industries where equipment operates under harsh thermal conditions and faces high risks of corrosion and oxidation, including:
- Power generation plants (boilers, turbines)
- Petrochemical and chemical processing equipment
- Metallurgical plants and furnaces
- Automotive and aerospace components exposed to high temperatures
- Industrial machinery needing enhanced surface protection in oxidizing or chemically aggressive environments
By applying coatings compliant with this standard, manufacturers and maintenance teams can extend service life, reduce downtime, and improve operational safety.
