For specific warning statements, see Section 7 and 9. About the Author Sabrin Gebarin.

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.

Copyright Stanhope—Seta Limited 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. ICS Number Code Within 7 working days. 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.

Oil Test Centrifuge | ASTM D

Operation – You operate the lid using the control panel. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Has programmable operation program which can be arbitrarily set for the lifting speed, automatic calculation of RCF value, 4. Create your own user feedback survey.

Detect lubricating oil n-pentane insoluble and toluene insoluble. It appeared that a high soot load caused the samples to become thick, but it was strange that the pentane insolubles test utilizing centrifugal solids separation did not report similar results.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. You can also save test parameters as a program so they can be quickly recalled.

Generally, results of these tests should correlate, but in this case they seemed to disagree with each other. Our main oil purifying and recycling machines: The difference between the two weights pentane and toluene is the estimated soot content in the sample.

Toggle navigation Toggle search. The mixture is then centrifuged to separate the insoluble material and the insoluble material is measured to determine the percentage of insolubles present.

The customer can oftentimes help when decisions are being made about what tests are most appropriate in a particular application. 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.

Historical Version s – view previous versions of standard.

Not exactly what you want? Although more expensive in certain cases, these tests are more appropriate for measuring soot than pentane and toluene insolubles by centrifuge. Note 1 Results obtained by Procedures A and B should not be compared since they usually give different values. Link to Active This link will always route to the current Active version of the standard. Chongqing Top Oil Purifier Co.

TOP Testers works on the development, production, market, technical and after-sale service for petrochemical analyzers, transformer substation electrical testing equipment and circuit detecting equipment. The TGA method involves placing the sample in an oven, where it is weighed continuously as the temperature is increased at specific increments. Honest Team – TOP always honestly treat you and keep faith to make you satisfied with every cooperation with us. 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.

Automatic Centrifuge

The Hazard Reduction System only requires connection to a compressed air supply and the centrifuge. The instrument is sensitive to the weight of the samples and an imbalance detector stops the centrifuge if the rotor head axtm an imbalance of over 8 grams. Strategies to Protect Grease Fittings from Contaminants. To investigate further, two additional pentane insolubles tests by membrane filtration ASTM D were run. Adopts frequency control technology, digital display of all kinds of parameters 3.

However, instead of centrifuging to separate the solid particles from the oil, the oil asstm passed through a submicron membrane.
