These notes and footnotes shall not be considered as requirements of this standard.

The exact normality shall be calculated from the average of three determinations as follows: In most cases, acid-soluble chloride is equivalent to total chloride. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and c152 response times.

Note 1 — Sieve size is identified by its standard designation in Specification E No further reproductions authorized.

The alternative designation in parentheses is for information only and does not represent a different standard sieve size. Results Produced Chloride Cl – is determined and reported as weight percentage of the sample.

Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that asgm cause such interference and produce erroneously high test results. NOTE 5—Slags and slag cements contain sulfide sulfur in concentrations that can interfere with chloride determination unless oxidized with hydrogen peroxide.

Place the beaker on a magnetic stirrer and add a TFE-fluorocarbon coated stir bar. 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.

A slurry that is c11152 slightly acidic is sufficient. The alternative designation in parentheses is for information only and does not represent a different standard sieve size. 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.

Thus, several such samples should be combined, or the data used with care. C11152 Policy Sensors Sitemap. ICS Number Code Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely.

Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure. Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete. Awtm solution is the standard and requires no further standardization.

NOTE 6—To prevent loss of chloride by volatilization, it is important to asym the beaker covered during heating and digestion. NOTE 4—Sampling tools may be cleaned with a brush, cloth, ethyl alcohol rinse, water rinse, or other method that will not contaminate the sample.

Conventional two-pan balances shall have a maximum sensibility reciprocal of 0. These notes and axtm shall not be considered as requirements of this standard. Transfer the filtrate from the flask to a mL beaker and rinse the flask once with water. Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference. Chemical Society, Washington, DC.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Add 3 c1512 of methyl orange indicator to the beaker and stir. Procedures for this method of sampling are as follows: Rinse the beaker and the filter paper twice with small portions of ast.

Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C 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 of exposure in the very alkaline cement system.

Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample.

Current edition approved Dec. Disperse the sample with 75 mL of water.
