However, due to solubility and reactivity issues described above, analysts often drastically reduce sample size, which tends to reduce the reproducibility of test results.
Only representative samples obtained as speci? Procedure NOTE 4—The precision of this test method will be affected by water droplets adhering to surfaces in the apparatus and therefore not asmt into the water trap to be measured.
Insert a loose cotton plug in the top of the condenser to prevent condensation of atmospheric moisture inside it. Strategies for Removing Water from Oil.
The end-point determination in KF titration occurs by means of bivoltametric indication. When complete, discard the contents of the trap asym add the volume of water as speci?
The stills and traps should be chosen to cover the range of materials and water contents expected. Note; clamp, bosshead and glassware available separately.
For bituminous emulsions refer to Test Method D Volumetric KF is most accurate in the range of ppm to percent water. Some products have stock, contact us anytime to get more information.
Current edition approved May 1, Used oils may also contain contaminants that can potentially interfere with direct KF analysis, such as trace metals, polyaromatic hydrocarbons, polychlorinated biphenyls, as well as various products of incomplete combustion. If you have any technical question, you are welcome to astk us any time. The precision when using the 2-mL trap or a 5—mL trap has not been established. Understanding Oil’s Saturation Point.
Read the volume of the water in the trap to the nearest scale division.
Distillation 1000ml Flask Heater
D95 — 05 ASTM International takes no position respecting the validity of any patent rights asserted in connection with atsm item mentioned in this standard. The Seta Distillation Flask Heater is a regulated heating mantel which has the capacity to accommodate a ml flask. Relevancy Transaction Level Response Rate. Eliminate these factors before repeating the veri? Always apply a very thin? Karl Fischer inKarl Fischer KF analysis has progressed from an esoteric laboratory procedure to a widely accepted instrumental method routinely used for water determination in the petrochemical industry.
Some of the modes by which water exists in lubricating oils can lead to catastrophic equipment failure.
Key Components of a Modern Volumetric KF Titrator Coulometric KF In coulometric KF, the iodine needed by the KF reaction is not ashm in the KF reagent, but is instead generated electrochemically in situ from iodide at the anode of the generator electrode, a component of the coulometric titration cell Figure 2. There are astm d95 suppliers, mainly located in Asia.
Ramin’ USA Corporation
Distillation ml Flask Heater Part Number The Seta Distillation Flask Heater is a regulated heating mantel which has the capacity to accommodate a ml flask. Best Ways to Test for Water in Oil.
The still, trap, and condenser may be connected by any suitable method that produces a leakproof joint. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or wstm phonefaxor service astm.
Standard test method for water in petroleum products and bituminous materials by distillation. Reactivity Certain compounds asmt the oil will undergo interfering side reactions either with methanol or iodine components of KF reagents. D95 xstm 05 the case of Style E; 0. A heater power indicator will illuminate when power is applied to the heater element.

Alternatively, specially preformulated KF reagents incorporating one or several of these solvents are commercially available for both volumetric and coulometric KF. Provide laboratory construction program design guidelines.
If there is a persistent ring of water in the condenser tube, carefully increase the rate of distillation or cut off the condenser water for a few minutes. The heating element is made of glass fibre which minimises damage to the flask in case of a slight impact between flask and heater.
Percent may be determined by mass or by volume. NOTE 3—Instead of standardizing on a particular apparatus speci?
