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. At this point, oxygen, rather than nitrogen, is introduced, which allows all the carbonaceous material mainly soot to combust and leaves the ast metal insolubles in the sample.

ASTM D893 Used Lubricating Oils N-pentane and Toluene Insolubles Test Kit

The soot percentage is calculated by measuring the difference between the weight aztm the sample before oxygen was introduced to the weight of the sample after it stabilized and all the soot is removed. For specific precautionary statements, see, and. Standard test method for sediment in water-emulsion polishes by centrifuge.

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.

Contact Supplier Start Order. Operation – You operate the lid using the control panel. You can contact me online or send offline message. Common causes of engine oil thickening include highly oxidized oil, glycol contamination, thermal degradation and severe soot contamination. It provides an indication of the materials that can readily be separated from the oil-solvent r893 by centrifuging.

Detect lubricating oil n-pentane insoluble and toluene insoluble. Vapour extracted is diluted with air, and is safely discharged into a non-hazardous area.

Oil Test Centrifuge | ASTM D

Setafuge Hazard Reduction System The optional Setafuge Hazard Reduction System prevents the uncontrolled release of hazardous vapours from the centrifuge.

The first test was conducted using a 0. Big rotor capacity, imported environmental qstm compressor and variable frequency motor. The toluene dissolves organic oxides, but not soot. Petroleum products – Determination of water and sediment in residual fuel oils – Centrifuge methods.

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.

No other units of measurement are included in this standard. Honest Team – TOP always honestly treat you and keep faith to make you satisfied with every cooperation with us. Although more expensive in certain cases, these tests are more appropriate for measuring soot than pentane and toluene insolubles by centrifuge. 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.

It is the responsibility of the user of this standard to establish asrm safety and health practices and determine the applicability of regulatory limitations prior to use.

The difference between the two weights pentane and toluene is c893 estimated soot content in the sample. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided x893 part of the standard. Conclusion Upon speaking to the laboratory personnel, it was discovered that when the pentane insolubles test was run, asttm additives dispersants in the oil appeared to have kept the soot suspended in the sample.

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

Standard Test Method for Insolubles in Used Lubricating Oils

Toggle navigation Toggle search. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Within 7 working days. Generally, results of these tests should correlate, but in this case they seemed to disagree with each other.

Dispersant additives keep soot from agglomerating. It provides an indication of the materials that can readily be separated from the oil-solvent mixtures by centrifuging. Gas-chromatography transformer oil gas analyzer DGA 7. Adopts frequency control technology, digital display of all kinds of parameters 3. Safety features – D8893 motor driven lid latch with a safety interlock to prevent centrifuge operation while the lid is unlocked. Click here for 6-place Centrifuge.

Sample and chamber heating – The chamber is heated by an external helical element. The insolubles are then dried and weighed, and the insolubles percentage is calculated. For specific warning statements, see Section 7 and 9.

ASTM D – 14() Standard Test Method for Insolubles in Used Lubricating Oils

Basically, this test separates insolubles from the oil after it has been mixed with solvents. To understand why the results of the pentane and toluene coagulated insolubles test did e893 coincide with TGA and membrane filtration tests, it is important to know how each test is performed and understand satm underlying theories.

We consists of departments respectively for technological development, machinery manufacture, instrument manufacture, quality control etc. Chongqing Top Oil Purifier Co. To investigate further, two additional pentane insolubles tests by membrane filtration ASTM D were run.
