Results obtained by Procedures A and B should not be compared since they usually give different values. Historical Version s — view previous versions of standard Translated Version s: At this point, oxygen, rather than nitrogen, is introduced, which allows all the carbonaceous material mainly soot to combust and leaves the other metal insolubles in the sample.

Contact Supplier Start Order. The difference between the two weights pentane and toluene axtm the estimated soot content in the sample. No other units of measurement are included in this standard.

The toluene dissolves organic oxides, but not soot. Basically, this test separates insolubles from the oil after it has been mixed with solvents. When the sample was centrifuged, the soot was moved along the side of the test tube instead of being forced to the bottom with the other insolubles. Instrument is equipped with awtm variety of safety protection, such as imbalance, over temperature, over speed, door cover and so on. For specific precautionary statements, see, and.

This is further supported by the fact that the soot passed through a 0. Our main oil purifying and recycling machines: Within 7 working days. The Seta Oil Test Centrifuge is a heating centrifuge fitted with a rotor head with four universal pivoting buckets. The mixture is centrifuged again and the insoluble material is weighed. Vapour extracted is diluted with air, and is safely discharged into a non-hazardous area.

After more investigation, the reason why one test was more successful than the other was discovered.

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 2 percent or 3 percent.

To sample for soot load, a pentane and toluene coagulated insolubles test ASTM D was run on the sample and results indicated less than 1 percent solids in the sample. Related Posts.
