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 asttm see 5. Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit.

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. For concrete submerged in seawater, using silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes.

It shall consist of a sponge or several sponges pre-wetted with a low electrical resistance contact solution. Originally approved in Current edition approved Nov. 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. Concrete surfaces that are coated or treated with sealers may not provide an accept- able electrical circuit.
