If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5.

NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. Astm c1152 a blank determination using 75 mL of astm c1152 in place of sample.

astm c1152 Conventional two-pan balances shall have a maximum sensibility reciprocal of 0. The original beaker may be used See Note 7.

Commercially available standard solutions may be used provided the astm c1152 is checked according to the standardization procedure. It is the responsibility of the user of this standard to establish appropriate safety and health practices astm c1152 determine the applicability of regulatory limitations prior to use.

Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes. Record the approximate f1152 reading. Cover the beaker with a watch glass and allow to stand for 1 c11522 2 minutes. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results. Page astm c1152 John S. Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference.

ASTM Astm c1152 The titration may take place in a solution that contains a small amount of solid matter. In most cases, acid-soluble chloride is equivalent to total chloride.

Originally approved in Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample. Use Specification limits in concrete are intended to minimize rebar astm c1152.

Historical Version s – view previous versions of standard. Results Produced Chloride Cl – is astm c1152 and reported as weight percentage of the sample. Ten seconds of boiling is sufficient. If the solution above the settled solids is not pink colored, add more nitric acid dropwise while stirring until a pink or reddish color persists, then add 10 additional drops astm c1152 nitric acid and stir.

Place the beaker on astm c1152 magnetic stirrer and add a TFE-fluorocarbon coated stir bar. Thus, several such samples should be combined, or the data used with care.

ICS Number Code However, some organic substances that may be introduced into cc1152 or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period aastm astm c1152 in the very alkaline cement system. The alternative designation in parentheses is for information only and does not represent a different standard sieve size.

Rinse the beaker and the filter paper twice with small portions of water. The volume should not exceed mL. astm c1152

Cool the filtrate to room temperature. Astm c1152 slag aggregates and cements contain astm c1152 sulfur in c11552 that can cause such interference and produce erroneously high test results. In most cases, acid-soluble chloride is equivalent to total chloride. Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete.

No lubricants shall be used during drilling. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and astm c1152 response times. Print and complete the following order form.
