The basic configuration of the electrical circuit is shown in Fig. Originally approved in 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 values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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 c8876 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.

It shall consist of a sponge or several sponges pre-wetted with a low electrical resistance contact solution. 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 asfm 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 c8766 and the concrete member.
