If accurate results can not be obtained, the solution should be discarded. Home Astm d Astm d April 21, Author: The ACE control system guarantees that the actual electrolysis current produced and the count rate displayed are always correctly synchronised, regardless of changes to the electrolysis cell resistance. Providing fast, accurate and reproducible determinations of water content in liquids, gases and powders. Summary of Test Method 3. For specific precautionary statements see 8.

A number in parentheses indicates the year of last reapproval. NOTE 1—For the best accuracy the solution should not be mixed or shaken after standing.

The completion of the reaction is detected with a platinum sensing electrode. Size px x x x x Designed to be equally suitable for meeting the routine needs of the Quality Control laboratory or the more demanding and varied requirements of research d133.

It is the responsibility of the user of this standard to establish appropriate safety and health practice and determine the applicability of regulatory limitations prior to use.

If a drifting end point is noted, an alternative solvent system or another titration method is warranted. General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Remove the sample aliquot from the top phase and inject it immediately into the titration cell. No other units of measurement are included in this standard.

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. Please copy and paste this embed script to where you want to embed Embed Script.

Initially, this solution should be mixed thoroughly and allowed to stand at room temperature for at least three days to achieve xstm equilibration. Request a Free Quote Right Now.

No further reproductions authorized. The degree of saturation of the water-saturated 1-Octanol varies. Home Astm d Astm d April 21, Author: Email Us or call toll-free: A detailed discussion of interfering substances can be found in the treatise on aquametry.

If accurate results can not be obtained, the solution should be discarded. Providing fast, accurate asmt reproducible determinations of water content in liquids, gases and powders.

The test specimen is injected into a titration cell where the iodine consumed by the reaction with water is electrolytically regenerated by anodic oxidation of iodide. Summary of Test Method 3.
