Syringes may be glass or plastic. Please copy and paste this embed script to where you want to embed Embed Script. Refer to Annex A1 for information on alternative solvent systems. If a drifting end point is noted, an alternative solvent system or another titration method is warranted. The endpoint is determined amperometrically with a platinum electrode that senses a sharp change in cell resistance when the iodine has reacted with all of the water in the test specimen.

The degree of saturation of the water-saturated 1-Octanol varies. They should be of a large enough gauge to allow for easy transfer of the sample.

A detailed discussion of interfering substances can be found in the treatise on aquametry. Summary of Test Method 3. Thank you for interesting in our services.

Please fill this form, we will try to respond as soon as possible. NOTE 1—For the best accuracy the solution should not be mixed or shaken after standing.

For specific precautionary statements see 8. If this drifting end point cannot be corrected, the water values should be regarded as suspect. The coulombs of electricity required to x1533 the necessary amount of iodine then is converted into the axtm of water present in the test specimen by use of the Faraday equation.

Stirring should be at such a rate that an oil layer will not form on top of the reagent. We are a non-profit group that run this website to share asmt. We need your help!

This test method requires the use of equipment specifically designed for coulometric titration. If accurate results can not be obtained, the solution should be discarded.

Significance and Use 4. Refer to Annex A1 for information on alternative solvent systems. A high water 4 Scholz, E. Syringes may be glass or plastic. The proposed reaction mechanism is as follows: No further reproductions authorized.

Initially, this solution should be mixed thoroughly and allowed to stand at room temperature for at least three days to achieve complete equilibration. This standard has been approved for use by agencies of the Department of Defense.

Remove the sample aliquot from the top phase and inject d11533 immediately into the titration cell. Please help us to share our service with your friends. Size px x x x x Excess oil may not mix thoroughly with the solvent system thus preventing the total water content of that test specimen from being measured properly.

Current edition approved Dec. A bottom drain cock is desirable but not necessary for removing reagents.

In the cell with a diaphragm the cathode compartment astmm similar reagents optimized for cathodic reduction. The endpoint is determined amperometrically with a platinum electrode that senses a sharp change in cell resistance when the iodine has reacted with all of the water in the test specimen. Originally approved in If a drifting end point is noted, an alternative solvent system or another titration method is warranted.

Plastic syringes shall be disposed of following each sample use. It is the responsibility of the user of this asym to establish appropriate safety and health practice and determine the applicability of regulatory limitations prior to use.

Wiley and Sons, Inc. No other units of measurement are included in this standard.
