Stirring should be at such a rate that an oil layer will not form on top of the reagent. If such an oil layer does form while at the instruments maximum stirrer speed, stop testing and remove the oil layer. 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. We need your help! Originally approved in In the cell with a diaphragm the cathode compartment contains similar reagents optimized for cathodic reduction. Thank you for interesting in our services.

Initially, this solution should be mixed thoroughly and allowed to stand at room temperature for at least three days to achieve complete equilibration. The astm d1533 of saturation of the water-saturated 1-Octanol varies. We are a non-profit group that run this website to share documents.

Plastic syringes shall be disposed of following each sample use. NOTE 1—For the best accuracy the solution should not be mixed or shaken after standing. Stirring should be at such a rate that an oil layer will not form on top of the reagent. For specific astm d1533 statements see 8.

It is the responsibility of the user of this standard to establish appropriate safety and d15333 practice and determine the applicability of regulatory limitations prior to use. In the cell with a diaphragm the cathode compartment contains similar reagents optimized for cathodic reduction.

The proposed reaction mechanism is as follows: Refer to Astm d1533 A1 for information on alternative solvent systems. Atsm px x x x x A high water 4 Scholz, E. Excess oil may not mix thoroughly with the solvent system thus preventing the total water content of that test specimen from being measured properly. If a drifting end point is noted, an alternative solvent system or another titration method is warranted.

In a sealed system, recleaning and redrying are not necessary for routine use. It may consist of two platinum meshes or wires separated by a diaphragm within astm d1533 glass assembly or two platinum meshes ast, wires not ast by a diaphragm.

This standard has been approved for use by agencies of the Department of Defense. 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. Please copy and paste this embed script to where you want to embed Embed Script. Karl Fischer instruments regenerate iodine coulometrically from the iodide in the Karl Fischer reagent.
