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. Sincere Communication – TOP sincerely communicate with you to guarantee the provided products to be your ideal ones.
Basically, this test separates insolubles from the oil after it has been mixed with solvents. The soot percentage is calculated by measuring the difference between the weight of the sample before oxygen was introduced to the weight of the sample after it stabilized and all the soot is removed. Note 1 Results obtained by Procedures A and B should not be compared since they usually give different values. The same procedure should be employed when comparing values obtained periodically on an oil in use or when comparing results determined by two or more laboratories.
Service Commitment – TOP bring you prompt, considerate and professional aftersale service and technical support, and explore technology future together. The Oil Test Centrifuge is a microprocessor controlled, programmable, heating centrifuge that meets the above standards. Located at Chongqing city–a southwest electromechanical manufacturing center as well as national municipality, Chongqing TOP is a professional leading manufacturer and supplier of oil purifiers and various related testers.
Adopts frequency control technology, digital display of all kinds of parameters 3. Initial analysis of the oil sample revealed that the oil was relatively new additive elements were similar to the 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. Detect lubricating oil n-pentane insoluble and toluene insoluble.
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.
Toggle navigation Toggle search. The first test was conducted using a 0. Online moisture content tester TPEE 5. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It provides an indication of the materials that can readily be separated from the oil-solvent mixtures by centrifuging. Although more expensive in certain cases, these tests are more appropriate for measuring soot than pentane and toluene insolubles by centrifuge.
No other units of measurement are included in this standard. This is further supported by the fact that the soot passed through a 0. We consists of departments respectively for technological development, machinery manufacture, instrument manufacture, quality control etc.
Setafuge Hazard Reduction System The optional Setafuge Hazard Reduction System prevents the uncontrolled release of hazardous vapours from the centrifuge. The customer can oftentimes help when decisions are being made about what tests are most appropriate in a particular application.
Also you can directly contact me at the following address: 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. Cloud point and pour point tester PT 8. This standard does not purport to address all of the safety concerns, if any, associated with its use. The Hazard Reduction System only requires connection to a compressed air supply and the centrifuge.
However, instead of centrifuging to separate the solid particles from the oil, the oil is passed through a submicron membrane. Initial observation of the oil sample showed it was thick and almost gel-like. Therefore, test results indicated a low insolubles reading. Standard test method for sediment in water-emulsion polishes by centrifuge. Gas-chromatography transformer oil gas analyzer DGA 7.
Standard Test Method for Insolubles in Used Lubricating Oils
The insolubles are then dried and weighed, and the insolubles percentage is calculated. Link to Active This link will always route to the current Active version of the standard. The same procedure should be employed zstm comparing values obtained periodically on an oil in use or when comparing results determined by two or more laboratories.
Historical Version s – view previous versions of standard Translated Version s: The astk dissolves organic oxides, but not soot. The system extracts vapour from near the top rim of the chamber, maintaining the pressure in the chamber at slightly below atmospheric.
Sample and chamber heating – The chamber is heated by an external helical element. The mixture is centrifuged again and the insoluble material is weighed. In addition to the materials separated by using Procedure A, this coagulation procedure separates some finely divided materials that may be suspended in the oil.
Strategies to Protect Grease Fittings from Contaminants. Generally, results of these tests should correlate, but in this case they ast to disagree with each other. Contact Supplier Start Order. You use the centrifuge to determine water and sediment in oils. The test is then repeated using toluene instead of pentane.

After more investigation, the reason why one test was more successful than the adtm was discovered. Common causes of engine oil thickening include highly oxidized oil, glycol contamination, thermal degradation and severe soot contamination.
