Chongqing Top Oil Purifier Co. Two lessons were learned from this discovery. Service Commitment – TOP bring you prompt, considerate and professional aftersale service and technical support, and explore technology future together.
This standard does not purport to address all of the safety concerns, if any, associated with its use. To sample for soot load, a pentane and toluene coagulated insolubles test Awtm D was run on the sample and results indicated less than 1 percent solids in the sample.
Standard – Standard Test Method for Insolubles in Used Lubricating Oils ASTM D –
We provides you with reliable oil purifiers such as transformer oil dd893, 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. Petroleum products – Determination of water and sediment in residual fuel oils – Centrifuge methods.
Link to Active This link will always route to the current Active version of the standard. In addition, if questionable test results are obtained, the laboratory can serve as a good second opinion and troubleshooter. Active view current version of standard. Recently, an engine oil sample was tested to determine the root cause of a failure that resulted in an engine seizing. 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.
It is the responsibility of the user of this standard to asstm appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Historical Version s – view previous versions of standard.
The mixture is centrifuged again aetm the insoluble material is weighed. The test is then repeated using toluene v893 of pentane. Initial observation of wstm oil sample showed it was thick and almost gel-like.
Strategies to Protect Grease Fittings from Contaminants. Also you can directly contact me at the following address: An inert nitrogen purge gas is used over the sample to enable the oil to evaporate without other reactions oxidation taking place.
When the weight stabilizes and remains stable for a certain duration, this signifies that all the oil has evaporated and only insolubles remain. Create your own user feedback survey. 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. You can also save test parameters as a program so they can be quickly recalled.

Discovery in Engine Oil Soot Testing Teaches Lesson
Sincere Communication – TOP sincerely communicate with you to guarantee the provided products to be your ideal asrm. Instrument is equipped with a variety of safety protection, such as imbalance, over temperature, over speed, door cover and so on.
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.
Results obtained by Procedures A and B should not be compared since they usually give different values.
You can set the rotation speed, temperature, acceleration rate and time using the control panel. Flash point tester open cup TPO 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.
The TGA method involves placing the sample in an oven, where it is xstm continuously as the temperature is increased at specific increments.
The difference between the two weights pentane and toluene is the estimated soot content qstm the sample. The Oil Test Centrifuge is a microprocessor controlled, programmable, heating centrifuge that meets the above standards. Adopts frequency control technology, digital display of all kinds of parameters 3. 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.
Setafuge Hazard Reduction System The optional Setafuge Hazard Reduction System prevents the uncontrolled release of hazardous vapours from the centrifuge. ICS Number Code First, a pentane solvent is mixed in with the oil to separate solids and oxidation products from the oil by lowering the viscosity.
Vapour extracted is diluted with air, and is safely discharged into a non-hazardous area. When the sample was centrifuged, the dd893 was moved along the side asgm the test tube instead of being forced to the bottom with the other insolubles. Big rotor capacity, imported environmental protection compressor and variable frequency motor.

The insolubles are then aastm and weighed, and the insolubles percentage is calculated. Acidity tester ACDI 3. 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. No other units of measurement are included in this standard. However, instead of centrifuging to separate the solid particles from the oil, the oil is passed through a submicron membrane.
