Instrument is equipped with a variety of safety protection, such as imbalance, over temperature, over speed, door cover and so on. You d8933 also save test parameters as a program so they can be quickly recalled. Operation – You operate the lid using the control panel.

ASTM D893 Lubricating Oils Insolubles Analyzer

However, instead of centrifuging to separate the solid particles from the oil, the oil is passed through a submicron membrane. R893 the weight stabilizes and remains stable for a certain duration, this signifies that all the oil has evaporated and only insolubles remain. First, had the TGA test or the ASTM D pentane insolubles test aztm 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.

Results obtained by Procedures A and B should not be compared since they usually give different values. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Contact Supplier Start Order. 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.

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.

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. Adopts frequency control technology, digital display of all kinds of parameters 3. Sample and chamber heating – The chamber is heated by an external helical element. 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.

Online moisture content tester TPEE 5. Detect lubricating oil n-pentane insoluble and toluene insoluble. To investigate further, two additional pentane insolubles tests by membrane filtration ASTM D were run. 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.

Initial observation of the oil sample showed it was thick and almost gel-like. Copyright Stanhope—Seta Limited TOP Oil Purifiers are widespread in the fields of electric power, petrifaction, mineral, shipbuilding, steel construction, bridge, automobile and railway, playing a great role in reducing energy consumption for clients as well as environmental pollution. 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.

Acidity tester ACDI 3. Cloud point and pour point tester PT 8. 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.

Within 7 working days. You can set the rotation speed, temperature, acceleration rate and time using the control panel. The Oil Test Centrifuge is a microprocessor controlled, programmable, heating centrifuge that meets the above standards.

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

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 system extracts vapour from near the top rim of the chamber, maintaining the pressure in the chamber at slightly below atmospheric.

Historical Version s – view previous versions of standard Translated Version s: The instrument is sensitive to the weight of the samples aetm an imbalance detector stops the centrifuge if the rotor head has an imbalance of over 8 grams.

Note 1 Results obtained by Procedures A and B should not be compared since they usually give different values. The Seta Oil Test Centrifuge is a heating centrifuge fitted with a rotor head with four universal pivoting buckets. Basically, this test separates insolubles from the oil after it has been mixed with solvents.

The first test was conducted using a 0. Although more expensive in certain cases, these tests are more appropriate for measuring soot than pentane and toluene insolubles by centrifuge.

Two lessons were learned from this discovery. Not exactly what you want? You can contact me online or send offline message. ICS Number Code The toluene dissolves organic oxides, but not soot.

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. Big rotor capacity, imported environmental protection compressor and variable frequency motor.

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.

The mixture is centrifuged d8893 and the insoluble material is weighed. At this point, oxygen, rather than nitrogen, is introduced, which asttm all the carbonaceous material mainly soot wstm combust and leaves the other metal insolubles in the sample.

It provides an indication of the materials that can readily be separated from the oil-solvent mixtures by centrifuging.
