Standard Information
- Standard Number: EN ISO 12944-2:2001
- Title: Paints and varnishes - Corrosion protection of steel structures by protective paint systems
- Part 2: Classification of environments
- Status: Current
Atmospheric Corrosivity Categories
The standard defines six atmospheric corrosivity categories:
- C1 (Very Low): Heated buildings with clean atmospheres
- C2 (Low): Rural areas with low pollution
- C3 (Medium): Urban and industrial atmospheres with moderate SO2 pollution
- C4 (High): Industrial areas and coastal areas with moderate salinity
- C5-I (Very High-Industrial): Industrial areas with high humidity and aggressive atmosphere
- C5-M (Very High-Marine): Coastal and offshore areas with high salinity
Durability Ranges
Expected durability of protection systems:
- Low (L): 2-5 years
- Medium (M): 5-15 years
- High (H): > 15 years
Environmental Factors
