7 Test report

Specifies methods for the verification of the effectiveness of the corrosion protection of reinforcing steel embedded in autoclaved aerated concrete (AAC) components or components of lightweight aggregate concrete with open structure (LAC). Provides three different methods of short-term term test (methods 1 to 3) and a long-term test (method 4). The test methods may be used to examine the fundamental suitability of a corrosion protective system in combination with a defined manufacturing process for the production of reinforced components.

This European Standard specifies methods for verification of the effectiveness of the corrosion protection of reinforcing steel embedded in autoclaved aerated concrete (AAC) components according to prEN 12602 or components of lightweight aggregate concrete with open structure (LAC) according to prEN 1520.
