Classes de résistance à la corrosion – CRC

CRC0

Protection très légère ou nulle pour les composants non soumis à des effets de corrosion

• Petites pièces standard dont l'aspect général n'a pas d'importance

CRC1

Protection légère pour les composants soumis à de faibles effets de corrosion

• Protection de transport et de stockage
• Pièces dont la surface ne doit pas répondre essentiellement à des critères d’apparence, pièces non visibles ou sous capotage p. ex.

CRC2

Medium protection for components subject to moderate corrosion stress such as

• externally visible parts with primarily decorative surface requirements
• Direct contact with a normal industrial environment or media such as coolants or lubricating agents

CRC3

Strong protection for components subject to high corrosion stress such as

• external, visible parts in direct contact with a normal industrial environment or media such as solvents and cleaning agents
• Primarily functional surface requirements
  

CRC4

Strong protection for components subject to extreme corrosion stress such as

• parts exposed to aggressive media, e.g. in the food or chemical industry
• Outdoor exposure under extreme corrosive conditions

These applications should be supported with special tests with the respective media when appropriate.
