A superscript epsilon indicates an editorial change since the last revision or reapproval. NOTE 4—Sampling tools may asgm cleaned with a brush, cloth, ethyl alcohol rinse, water rinse, or other method that will not contaminate the sample. Place the delivery tip of the 10 mL buret filled to the zero mark with standardized 0.
Specification D for Type I reagent water.
Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference. Instructions Sample mass should be at least 25 grams 1 oz of dried, finely powdered sample. Current edition approved Dec.
These notes and footnotes shall not be considered as requirements of this standard. Note 1 — Sieve size is identified by its standard designation in Specification E Place the beaker on a magnetic stirrer and add a TFE-fluorocarbon coated stir bar. NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations. 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.
Parte 1 de 2 Designation: Submit the concrete mix design if the results will be expressed as Cl – percentage of cement.

Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C Rinse the beaker and the filter paper twice with small portions of water.
No lubricants shall be used during drilling. The titration may take place in a solution that contains a small amount of solid matter. Heat the covered beaker rapidly to boiling and remove from hot plate. Conventional two-pan balances shall have a maximum sensibility reciprocal of 0.
Historical Version s – view previous versions of standard. No further reproductions authorized. 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 of nitric acid and stir. Astm c astm normas fibra de vidrio. Astm a Astm a A number in parentheses indicates the year of last reapproval.
Concrete farthest from a surface into which chloride has penetrated often provides chloride data close to that of the originally placed fresh concrete. A digital readout is preferred but not required.
Procedures for this method of sampling are as follows: 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 exact normality shall be calculated from the average of three determinations as follows: 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. A slurry that is only slightly acidic is sufficient.
The volume should not exceed mL. Print and complete the following order form. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results. If you need more info or have any questions, please note the Lab ID number 37 and contact us at:. 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.
Some values have only SI units because the inch-pound equivalents are not used in practice. Directreading balances shall have a sensitivity not exceeding 0.

Do not allow sample to boil more than a few seconds See Note 6. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ICS Number Code 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.
Order Form 2 Email complete form to contact listed zstm. Thus, several such samples should be combined, or the data used with care. Originally approved in Some values have only SI units because the inch-pound equivalents are not used in practice.

Use Specification limits in concrete are intended to minimize rebar corrosion. Treatment with hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference.
Excessive amounts of acid can erode the silver chloride coating on the silver billet electrode prematurely.
