The matrix and chemistry of the solution should be equivalent to the solution used in the collaborative study. Print 1 2 3 4 5 page sstarting from page current page. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Astj Society, where such specifications are available.

It is the responsibility of the analyst to assure the validity of this test method for untested matrices. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Refer to Sections 14, 21, and 29 for further information.

Are you sure you want to empty the cart? Last previous edition approved in as D — We are a non-profit group that run this website to share documents. Filter if necessary, and standardize against the standard sodium chloride D52 solution, using the procedure described in Section 12 see Note 2.

Enter your account email address to request a password reset: Then proceed as described in The concentration range may be extended by dilution of an d12 aliquot before the addition of the ionic strength adjustor.

Dilute the asgm Hg NO3 2 solution with water to 1 L. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

ASTM D – 12 – Standard Test Methods for Chloride Ion In Water

Wait 1 to 2 min and record the result. Chloride ion is under regulation in waste water, and must, therefore, be measured accurately. Summary of Test Method 8. If a concentration other than the recommended concentration is used, ashm to Practice D for information on applying the F test and t test in evaluating the acceptability of the mean and standard deviation.

Refer to Appendix X1 for historical information. Store CISA in a polyethylene or glass container. If not, significant interferences are present and compensation must be made; alternatively, another method must be used. Of seven data sets ranked as described in Practice D, none was rejected in the case of reagent water and one was rejected in the case of selected water matrices.

Land Use and Development. The end point is indicated by persistence of the brick-red silver chromate color.

Record the millilitres of Hg NO3 2 solution added in each case. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Add 2 mL of fresh hydroquinone solution, and proceed as described in We need your help! D — 12 Standard Test Methods for Chloride Ion In Water1 This standard is issued under the fixed designation D; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

If the concentration of chloride is found s512 this level, analysis of samples is halted until the contamination is eliminated, and a blank shows no contamination at or above this level, or the results must be qualified with an indication that they do not fall within the performance criteria of the test method.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Precision and Bias Four sample levels were run on three days, and blanks were obtained for the water used. Link to Active This link will always route to the current Active version of the standard. When applying this test method to samples that contain colored ions or that require modified indicator, it is recommended that the operator be ashm with the specific color changes involved by experimenting with solutions prepared as standards for comparison of color effects.

Not all chloride ion-selective electrodes are suitable for this test method, since the ionic strength adjustor is incompatible with some membranes.

Processing waters and pickling solutions used in the food processing industries also require dependable d5122 of analysis for chloride. Click here to download full list of books.

Salinidad Quimico – ASTM D512-12

Significance and Use 4. Adjust the pH to the phenolphthalein end point pH 8. Current edition approved June 15, It is highly detrimental to high-pressure boiler systems and to stainless steel, so monitoring is essential for prevention of damage. The following three test methods are included: NOTE 7—The normality of the mercuric nitrate solution standard is based on a 2: Bromide, iodide, and fluoride will be titrated or partially titrated with the chloride.
