New VDI guideline on corrosion damage to metallic components
Product damage causes economic losses due to production downtime, consequential damage and necessary repair measures and can also endanger people. However, targeted measures to remedy and prevent damage can only be introduced if the causes of damage and the influences of faults are clarified through systematic investigations. Damage analysis serves this purpose.
The Association of German Engineers (VDI e.V.) is a major German technical standard setter and regularly publishes guidelines for best manufacturing practice. A new guideline now deals with the subject of corrosion. Corrosion is one of the most common causes of damage to metallic components, especially when they are in contact with aqueous media. The guideline VDI 3822 Sheet 1.2 E describes in detail the various types of damage, damage phenomena, causes and processes that occur in such cases of damage. Analyzing this damage is a crucial step in developing targeted measures to prevent and rectify damage.
VDI 3822 Sheet 1.2 E focuses on the scientifically sound selection of suitable test methods and the structured and comprehensible evaluation of the individual results obtained. The guideline thus offers specialists, materials experts and quality managers in particular a valuable tool for root cause analysis and risk assessment of corrosion problems.
The guideline is part of the comprehensive VDI 3822 series of guidelines, which is dedicated to the systematic failure analysis of technical products. Its aim is to use standardized procedures to increase the safety, durability and cost-effectiveness of technical systems. A well-founded damage analysis not only enables the reconstruction of the damage process, but also the targeted optimization of materials, processes and products.
The VDI 3822 Sheet 1.2 E "Failure analysis; damage to metal products due to corrosion in aqueous media" was published in January 2025 and is available for €147.50 from DIN Media available.
