It is often necessary to astk other data such as chloride contents, depth of carbonation, delamination survey findings, rate of corrosion results, and environmental exposure conditions, in addition to corrosion potential measurements, to formulate conclusions concerning corrosion activity of embedded steel and its probable effect on the service life of a structure.

Concrete cover in excess of 3 in. This standard is qstm available to be included in Standards Subscriptions.

The system was tested aatm a building of the University complex, where its performance was evaluated using three different reference electrodes, obtaining an error over the measurement, between the standard and the system, of 6.

Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit.
