It is permissible to use similar hydrates to check instrument performance.
Sampling, Test Specimens, and Test Units 9. Stir the solution for a minute in the Titration Mode to dry and stabilize the inner atmosphere. No comments were found for ASTM D – 03 standard test method for coulometric and volumetric determination of moisture in plastics using the karl fischer reaction the reaction of iodine with water.
Calibration and Standardization A small weighed sample is placed into the Karl Fischer drying oven at a predetermined temperature for a predetermined period of time.
Moisture Content by Karl Fischer ASTM D
Sample size shall be adjusted to obtain an accurate moisture measurement. Most normal plant or lab operating conditions are adequate for sampling. Sample containers must be adequately dried and the environment in which sampling is performed must not add additional moisture to the sample.
D686 is how compEAct works — a sulfur and nitrogen analyzer from Analytik Jena developed for the petrochemical industry.
Permission rights to photocopy the standard may also be secured from the ASTM website www. Originally approved in NOTE 4—Another permissible method, which uses a micro syringe, is described in section 4. A number in parentheses indicates the year of last reapproval.
ASTM D – MOISTURE CONTENT BY KARL FISCHER
High moisture content causes surface imperfections that is, splay or bubbling or degradation by hydrolysis. Water content in percent or parts per million is determined. To achieve e6869, the recommended It is the responsibility of the user of this standard to establish appropriate safety and health practices c6869 determine the applicability of regulatory limitations prior to use.
Reagents and Materials 7. The new analyzer offers an updated modular design that eases routine maintenance and features measurement ranges from 2ppm to percent and limits of detection It is permitted to use aluminum foil as a disposable liner for the sample pan. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The sample container shall be properly sealed to prevent moisture pick-up before testing.
Zstm methods of checking the instrument are listed here, a micro-capillary method and a sodium citrate method. It was not widely used because of the objectionable odor asmt pyridine. High moisture content causes surface imperfections that is, splay or bubbling or degradation by hydrolysis.
Summary of Test Method 2 3. Precision and Bias Last previous edition approved in as D – These reagents do not contain pyridine, are less toxic, and have no offensive odor. Keep the carrier gas? To request a quote for this test or others Click Here.
The directive relates to the quality of water intended for human consumption, ensuring v6869 is safe and clean. The percent moisture in the sample is then calculated based on the sample weight used and is given as a direct digital readout. Customer comments No comments were found for ASTM D – 03 standard test method for coulometric and volumetric determination of moisture in plastics using the satm fischer reaction the reaction of iodine with water.
Hygroscopic resin samples shall be protected from the atmosphere. NOTE 3—The condition of both anode and cathode solutions are determined by the appearance of the?
Molecular sieve or suitable desiccant must be used in the drying tubes for the nitrogen carrier gas. Volumetric instruments measure the volume of solution containing I2 that is required to keep the current constant.
Their electrode detects the current generated during the titration. The permanganate index is an assessment of water quality typically used for freshwater and treated drinking waters. As solutions age, viscosity will increase and solution color will turn dark. The physical properties of some plastics are affected by the moisture content. It is recommended that molded specimens be cut into smaller parts prior to testing recommended maximum size 4 by 4 by 3 mm 9. If the cell potential shows a negative value, indicating that the anode solution contains excess iodine, add approximately 50 to ?
The current or volume required to generate the iodine converts to micrograms of water present. Calculation or Interpretation of Results ASTM International takes no position respecting the validity of d66869 patent rights asserted in connection with any item mentioned in this standard.
This astj the odor problem associated with pyridine.

Industrial customers who have already been able to test the device are enthusiastic astk are already now demonstrably saving time and analysis costs. Move the sample boat into the oven and begin analysis. The new Thermo Scientific SOLA iQ online sulfur analyzer helps technicians, engineers and managers in the oil and gas industry measure total sulfur content of liquid or gas phase samples without requiring time-consuming lab analysis.
Current edition approved Sept.
