The system extracts vapour from near the top rim of the chamber, maintaining the pressure in the chamber at slightly below atmospheric.
Standard – Standard Test Method for Insolubles in Used Lubricating Oils ASTM D –
Current Issue Archive Asfm. You can contact me online or send offline message. On basis of mature development and manufacture technology and highly qualified production management team, the products own high quality, easy operation, excellent performance and lone service life. Our main oil purifying and recycling machines: When the weight stabilizes and remains stable for a certain duration, this signifies that all the oil has evaporated and only insolubles remain.
Has programmable operation program which can be arbitrarily set for the lifting speed, automatic calculation of RCF value, 4. No other units of measurement are included in this standard. The instrument is sensitive to the weight of the samples and an imbalance detector stops the centrifuge if the asmt head has an imbalance of over 8 grams. As the sample passes through the fine mesh patch, the insoluble material remains on the upstream surface of the patch while the remaining sample passes through.
The mixture is then centrifuged to separate the insoluble material and the insoluble material is measured to determine the percentage of insolubles present.
ASTM D893 Used Lubricating Oils N-pentane and Toluene Insolubles Test Kit
Historical Version s – view previous versions of standard. About the Author Sabrin Gebarin. The insolubles are then dried and weighed, and the insolubles percentage is calculated.
Two lessons were learned from this discovery.
ASTM D – 14() Standard Test Method for Insolubles in Used Lubricating Oils
The vacuum inside the chamber is monitored by a vacuum switch, and the system is interlocked to ensure safe operation of the centrifuge. Referenced Documents purchase separately The documents listed below are astj within the subject standard but are not provided as part of the standard. Historical Version s – view previous versions of standard Translated Version s: Flash point tester close cup TPC Cloud point and pour point tester PT axtm.
Acidity tester ACDI 3. Copyright Stanhope—Seta Limited Results obtained by Procedures A and B should not be compared since they usually give different values. Therefore, test results indicated a low insolubles reading. Initial observation of the oil sample showed it was thick and almost gel-like. This is further supported by the fact that the soot passed through a 0.
The test is then repeated using toluene instead of pentane. The customer can oftentimes help when decisions are being made x893 what tests are most appropriate in a particular application. 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. 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.
Within 7 working days. 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. The Hazard Reduction System only requires connection to a compressed air supply and the centrifuge. Safety features – A motor driven lid latch with a safety interlock to prevent centrifuge operation while the lid is unlocked. For specific warning statements, see Section 7 and 9. 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.
You can also r893 test parameters as a program so they can be quickly recalled. Chongqing Top Oil Purifier Co.
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.
Contact Supplier Start Order. The Best Gets Better: It provides an indication of the materials that can readily be separated from the oil-solvent mixtures by centrifuging.
The centrifuge is fitted with a safety interlock to prevent the rotor running when the lid is unlocked. We consists of departments respectively for technological development, machinery manufacture, instrument manufacture, quality control etc.
Although more expensive in certain cases, these tests are more appropriate for measuring soot than pentane and toluene insolubles by centrifuge. 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. To investigate further, two additional pentane insolubles tests by membrane filtration ASTM D were run. Setafuge Hazard Reduction System The optional Setafuge Hazard Reduction System prevents the uncontrolled release of hazardous vapours from the centrifuge.
Results obtained by Procedures A and B should not be compared since they usually give different values. Create your own user feedback survey.
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.
Sample and chamber heating – The chamber is heated by an external helical element. Link to Active This link will always route to the current Active version of the standard. 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.
