This European Standard specifies the test methods for verification of the effectiveness of the corrosion protection of reinforcing steel embedded in components of autoclaved aerated concrete (AAC) according to prEN 12602 or in components of lightweight aggregate concrete with open structure (LAC) according to prEN 1520. Tests according to this European Standard are not required for LAC-components if corrosion protection is achieved by embedding the reinforcing bars completely in a zone of concrete with closed structure according to prEN 1520:2002, 5.8.3.3. Three different methods of short-term tests (methods 1 to 3) are provided. The test methods can 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. They can also be used for current production control. NOTE The specification of three different short-term test methods is based on historical reasons and established procedures rather than on technical needs.
