This standard (Part IV ) covers the method for determining the effectiveness of corrosion protection of the reinforcement bars embedded in autoclaved cellular concrete. In this method of test the effectiveness of corrosion protection of reinforcement bars is determined by exposure of samples to humid conditions at two widely different temperatures alternatively. The method is an accelerated test for corrosion under conditions, which are as close as possible to those experienced in practice.
