Use of a very soft annealed steel wire may allow use of identical thread diameters for the two wires. The test is considered to start at this point. Test Method D is now available for sludge measurement. Redistilled n-Heptane conforming to 6.

Position the bottom end of the sampling tube inside the catalyst coil. This can be accomplished as follows. Similar wire conforming to BS is also satisfactory. Clean the interiors of the test tubes, exteriors of the condensers, and both interiors and exteriors of the oxygen delivery tubes with cleaning reagent. Methods of test for petroleum and its products. Preparation of Apparatus 8. Rinse thoroughly with tap water until all acid is removed. Determination of the oxidation stability of inhibited mineral oils the TOST test.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. D — 02 Dimensions are in millimetres inches. Determination of the oxidation stability of middle-distillate fuels. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.


For dark-colored oils, the use of potentiometric titration aastm as Test Method D to measure the end point may be advantageous. Standard test method for determination of the sludging and corrosion tendencies of inhibited sstm oils.

Warning— Compressed gas under high pressure. Measure the sample temperature by a thermometer positioned in the oxidation cell by a thermometer bracket, as in Fig.

Before use it should be inspected to assure that no corrosion products or contaminating materials are present. To allow for heating of the stem portion of the thermometer above the immersion point in the upper portion of the test cell, subtract 0.

All dimensions are in millimetres inches 1. If a viewing window is dd943 in the design, this viewing window shall be? Adjust the rate of? Place aztm condenser over the oxygen delivery tube and test tube. The oxidation test tube has a calibration line at mL.


A number in parentheses indicates the year of last reapproval. NOTE 10—Beyond 10 h, oil removal causes the metal catalyst coil to be exposed to the atmosphere.

The correct level for water additions asttm, if desired, be indicated by a movable metal strip Fig. Type Stainless Steel, 22 Gage 0. The test method is also used for testing other oils such as hydraulic oils and circulating oils having a speci? Then wipe with dry absorbent cotton until all loose particles of metal and abrasive have been removed. Marking the upper oil level of the? Alternatively, thin stainless steel wire may be used.


The number of test hours required for the oil to reach 2. The values given in parentheses are for information only. Standard test method for oxidation characteristics of inhibited mineral oils. Summary of Test Method 3. Any arrangement that leads to the coil con?

It should be recognized, however, that correlation between results of this method and the oxidation stability of a lubricant in? Place the oxygen delivery tube with the coil into the test tube. Alternatively, temperature—measuring devices of equal or better accuracy may be used.

After each oil sample is taken, the indicator is moved to the new oil level before continuing the test. The temperature e943 system uses a PT probe to ensure long term temperature stability without routine maintenance or re-calibration.

Add a desiccant bag that has been folded lengthwise to? It is important to strictly adhere to the procedure and schedule for sampling for acid number.
