To investigate further, two additional pentane insolubles tests by membrane filtration ASTM D were run. 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.
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.
You can also save test parameters as a program so they 8d93 be quickly recalled. 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.
Not exactly what you want? The mixture is then centrifuged to separate the insoluble material and asym insoluble material is measured to determine the percentage of insolubles present.
Also you can directly contact me at the following address: Petroleum products – Determination of water and sediment in residual fuel oils – Centrifuge methods.
Safety features – A motor driven lid latch with a safety interlock to prevent centrifuge operation while the lid is unlocked. Within 7 working days. Link to Active This link will always route to the current Active version of the standard.
Instrument is equipped with a variety of safety protection, such as imbalance, over temperature, over speed, door cover and so on. 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.
We provides you with reliable oil purifiers such as transformer oil purifier, turbine oil purification machine, hydraulic oil purifier, lubricating oil filtration machine, fuel oil restoration, oil and water separator, oil regeneration equipment, waste oil recycling equipment etc. When the weight stabilizes and remains stable for a certain duration, this signifies that all the oil has evaporated and only insolubles remain.
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. Note 1 Results obtained by Procedures A and B should not be compared since they usually give different values. Setafuge Hazard Reduction System The optional Setafuge Hazard Reduction System prevents the uncontrolled release of hazardous vapours from the centrifuge.

ASTM D893 Lubricating Oils Insolubles Analyzer
First, had the TGA test or the ASTM D pentane insolubles test using a membrane not also been astmm, the oil analysis results would have shown that soot was not above critical levels usually about 2 percent or 3 percent. 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.
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. An inert nitrogen purge gas is used over the sample to enable the oil to evaporate without other reactions asrm taking place.

Click here for 6-place Centrifuge See detailed specifications Available accessories Request a quotation Download a brochure pdf More products in this subcategory. Common causes of engine oil thickening include highly oxidized oil, glycol contamination, thermal degradation and severe soot contamination. The mixture is centrifuged again and the insoluble material is weighed. The TGA method involves placing the sample in an oven, where it is weighed continuously as the temperature is increased at specific increments.
Big rotor capacity, imported environmental protection compressor and variable frequency motor.
Chongqing Top Oil Purifier Co. You can set the rotation speed, temperature, acceleration rate and time using the control panel.
To understand why the results of the pentane and toluene coagulated insolubles test did not coincide with TGA and membrane filtration tests, it is important to know how each test is performed and understand the underlying theories. For specific precautionary statements, see, and. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Cloud point asttm pour point tester PT 8. 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 e893.

The toluene dissolves organic oxides, but not soot. For specific warning statements, see Section 7 and 9. The instrument is sensitive to the weight of the samples and an imbalance detector stops the centrifuge if the rotor head has an imbalance of over 8 grams.
