NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. Ten seconds of boiling is sufficient. For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old. Current edition approved Dec.

A superscript epsilon indicates an editorial change since the last revision or reapproval. Thus, several such samples should be combined, or the data used with care.

If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5. Remove the beaker and wipe the electrodes with absorbent paper. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes.
cc1152 Rinse the beaker and the filter paper twice with small portions of water. Any rapid weighing device that may be provided, such as a chain, damped motion, or heavy riders, shall not increase the basic inaccuracy by more than 0.

Cool the filtrate to room temperature. A digital readout is preferred but not required. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
Print and complete the following order form. Do not allow sample to boil more than a few seconds See Note 6. Axtm the delivery tip of the 10 qstm buret filled to the zero mark with standardized 0.
Concrete farthest from a surface into which chloride has asgm often provides zstm data close to that of the originally placed fresh concrete.
Results Produced Chloride Cl – is determined and reported as weight percentage of the sample. Note 1 — Sieve size is identified by its standard designation in Specification E Penetration of deicer salt and seawater can be assessed by profiling chloride asfm at various positions in the sample.
Originally approved in Cover the beaker with a watch glass and allow to stand for 1 to 2 minutes. The original beaker may be used See Note 7. The titration may take place in a solution that contains a small amount of solid matter. Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure.

Dilute to 1 L in a volumetric flask and mix thoroughly. Qstm number in parentheses indicates the year of last reapproval. Parte 1 de 2 Designation: Samples should be oven-dried and ground to pass a No.
Heat the covered beaker rapidly to boiling and remove from hot plate. Some values have only SI units because the inch-pound equivalents are not used in practice.
