Current Issue Archive Advertise. The mixture is then centrifuged to separate the insoluble material and the insoluble material is measured to determine the percentage of insolubles present. Safety features – A motor driven lid latch with a safety interlock to prevent centrifuge operation while the lid is unlocked.

Sample and chamber heating – The chamber is heated by an external helical element. For specific warning statements, see Section 7 and 9. Copyright Stanhope—Seta Limited The test is then repeated using toluene instead of pentane.

Discovery in Engine Oil Soot Testing Teaches Lesson

Detect aatm oil n-pentane insoluble and toluene insoluble. Initial analysis of the oil sample revealed that the oil was relatively new additive elements were similar to aetm reference oilit did not appear to be oxidized reasonable acid numberand there was no sign of glycol contamination or wrong oil added no unusual additive elements were present in the used oil that did not show up in the reference oil.


The mixture is centrifuged again and the insoluble material is weighed. Initial observation of the oil sample showed it was thick and almost gel-like.

The Best Gets Better: We consists of departments respectively for technological development, machinery manufacture, instrument manufacture, quality control etc. First, a pentane solvent is mixed in with the oil to separate d983 and oxidation products from the oil by lowering the viscosity.

Chongqing Top Oil Purifier Co. Click here for 6-place Centrifuge. Acidity tester ACDI 3. It provides an indication of the materials astn can 8d93 be separated from the oil-solvent mixtures by centrifuging. Link to Active This link will always route to the current Active version of the standard. This is further supported by the fact that the soot passed through a 0.

Gas-chromatography transformer oil gas analyzer DGA 7. Our main oil purifying and recycling machines: Results obtained by Procedures A and B should not be compared since they usually give different values. The TGA method involves placing the sample in an oven, where it is weighed continuously as the temperature is increased at specific increments.

After more investigation, the reason why one test was more successful than the other was discovered. Not exactly what you want? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.


Seta Oil Test Centrifuge – 4 place

First, had the TGA test or the ASTM D pentane insolubles test using a membrane not also been conducted, the oil analysis results would have shown that soot was not above critical levels usually about c893 percent or 3 percent. You can set the rotation speed, temperature, acceleration rate and time using the control panel.

The difference between the two weights pentane and toluene is the asrm soot content in the sample. In addition, if questionable test results are obtained, the laboratory can serve as a good second opinion and troubleshooter. It uses a single chip microcomputer control system, man-machine friendly operation interface 2.

Standard Test Method for Insolubles in Used Lubricating Oils

The instrument is sensitive to the weight of the samples and an imbalance x893 stops the centrifuge if the rotor head has an imbalance of over 8 grams. Conclusion Upon speaking to the laboratory personnel, it was discovered that when the pentane insolubles test was run, the additives dispersants in the oil appeared to have kept the soot suspended in the sample.

Active view current version of standard. At this point, oxygen, rather than nitrogen, is introduced, which allows ast the carbonaceous material mainly soot to combust and leaves the other metal insolubles in the sample.
