Disperse the sample with 75 mL of water.
No lubricants shall be used during drilling. Print and complete the following order form.
Note 1 — Sieve size is identified by its standard designation in Specification E Heat the covered beaker rapidly to boiling and remove from hot plate. Asfm you need more info or have any questions, please note the Lab ID number 37 and contact us at:. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Penetration of deicer salt and seawater can be assessed by profiling chloride concentration at various positions in the sample.
Conventional two-pan balances shall have a maximum sensibility reciprocal of 0.
Make a blank determination using 75 mL of water in place of 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.
The alternative designation in parentheses is for information only and does not represent a different standard sieve size. Remove the beaker and wipe the electrodes with absorbent paper. Do not allow sample to boil more than a few seconds See Note 6. The alternative designation in parentheses is for information only and does not represent a different standard sieve size. 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.
Procedures for this method of sampling are as follows: In most cases, acid-soluble chloride is equivalent to total chloride. Concrete and Concrete Aggregatesand is the direct responsibility of Subcommittee C 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.
Such chloride will be detected by the use of this method. NOTE 6—To prevent loss of chloride by volatilization, it is important to keep the beaker covered during heating and digestion. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that can cause such interference and produce erroneously high test results. Such samples may be unrepresentative, especially when the nominal maximum coarse aggregate size is 25 m 1 in. Current edition approved Dec.
For testing to meet water soluble specification limits, tests should be performed on samples at least 28 days old. A slurry that is only slightly acidic is sufficient. Cool the filtrate to room temperature.

If you need more info or have any questions, please note the Lab ID number 37 and contact us at: Treatment with hydrogen peroxide, as discussed in Test Methods Cis used to eliminate such interference. Some values have only SI units because the inch-pound equivalents are not used in practice.
Commercially available standard solutions may be used provided the normality is checked according to the standardization procedure. NOTE 8—It is advisable to maintain constant temperature during measurement, as the solubility of silver chloride varies markedly with temperature at low concentrations.

However, some organic substances that may be introduced into mortar or concrete contain chloride ast, is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of exposure in satm very alkaline cement system.
Immerse the electrodes into the solution, taking care that the stir bar does not strike the electrodes. Order Form 2 Email complete form to contact listed below. Directreading balances shall have a sensitivity not exceeding 0. Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference.
Historical Version s – view previous versions of standard. ASTM Volume Samples should be oven-dried and ground to pass a No. 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.
Some values atsm only SI units because the inch-pound equivalents are not used in practice. Record the approximate millivoltmeter reading.
