Clean all sampling tools prior to each sampling operation See Note 4. Some values v1152 only SI units because the inch-pound equivalents are not used in practice.
If you need more info or have any questions, please note the Lab ID number 37 and contact us at:. Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample. Chemical Society, Washington, DC. Conventional two-pan balances shall have a maximum sensibility reciprocal of 0. Place the delivery tip of the 10 mL buret filled to the zero mark with standardized 0. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
If you need more info or have any questions, please note the Lab ID number 37 and contact us at: 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.
The original beaker may be used See Note 7. ICS Number Code Order Form 2 Email complete form to contact listed below. Make a blank determination using 75 mL of water in place of sample.
Astm a Astm a Procedures for this method of sampling are as follows: In most cases, acid-soluble chloride is equivalent to total chloride. Cover the beaker with a watch glass and allow to stand for 1 to 2 minutes. Cool the filtrate to room temperature. This solution is the standard and requires no further standardization. CM or as required for the purpose satm the investigation. Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference.
Specification D for Type I reagent water. A superscript epsilon indicates an editorial change since the last revision or reapproval.
NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. No lubricants shall be used during drilling. Treatment with hydrogen peroxide, as discussed in Test Methods Cis asttm to eliminate such interference.

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. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Commit- tee onAnalytical Reagents of theAmerican Chemical Society5.
Page and John S. Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure.

Some values have only SI units because the inch-pound equivalents are not used in practice. Do not allow sample to boil more than a few seconds See Note 6. If the smell of hydrogen sulfide is strongly present, add 3 mL of hydrogen peroxide See Note 5.
No further reproductions authorized. The volume should not exceed mL. Rinse the beaker and the filter paper twice with small portions of water. Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely. Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes.
A slurry that is only slightly acidic is sufficient. Dissolve in water and dilute to exactly 1 L in a volumetric flask and mix thoroughly. NOTE 9—If the tip of the buret is out of the solution, any adhering droplet should be rinsed into the beaker with a few millilitres of water following each titration increment. NOTE 7—It is not necessary to clean all the slurry residue from the sides of the beaker, nor is it necessary that the filter remove all the fine material.
Disperse the sample with 75 mL of water. 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. NOTE 5—Slags and slag cements contain sulfide sulfur in concentrations that can interfere with chloride determination unless oxidized with hydrogen peroxide. Link to Active This link will always route to the current Active version of the standard.
Dilute to 1 L in a volumetric flask and mix thoroughly. These notes and footnotes shall not be considered as requirements of this standard. 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.
The alternative designation in parentheses is for information only and does not represent a different standard sieve size.
For cement products, chloride can also be reported as percentage of the cement component if the content is provided or determined.
A number in parentheses indicates the year of last reapproval. However, some organic substances that may be introduced into mortar 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.
