Concrete surface in building interiors and desert environments lose sufficient moisture so that the concrete resistivity becomes so high that special testing techniques not covered in this test method may be required see 5.

Concrete cover in excess of 3 in. It is often necessary to use 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.

The sponge may be folded around and attached to the tip of the reference electrode so that it provides electrical continuity between the porous plug and the concrete member. The basic configuration of the electrical circuit is shown in Fig.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Concrete surfaces that are coated or treated with sealers may not provide an accept- able electrical circuit.

The basic configuration of the electrical circuit is shown in Fig. Significance and Use 4. It is often necessary to use other data such as chloride contents, depth of carbonation, delamination survey findings, rate of ast 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.
