Therefore, use the applicable apparatus and techniques described in Practice D Store glassware in a dry dust-free condition until ready to use.

When an actual test sample is used, remove the thermometer immediately after temperature measurement is complete. Your comments will receive careful consideration at a meeting of the responsible technical committee1, which you may attend. Then withdraw 6 mL of test oil into the syringe, hold the syringe tube vertically for 15 to 20 s to allow water to settle to the bottom of the syringe tube, and adjust the sample dd943 to 3 mL while holding the syringe vertically. The bottom of the sampling tube is positioned at 6 6 mm 6 6 0.

The thermometer is held in the bracket by two? The test method is also used for testing other oils such as hydraulic oils and circulating oils having a speci?

NOTE 9—The value 2. Gas reduces oxygen available for breathing. Standard test method for determination of the sludging and corrosion tendencies of inhibited mineral oils. The use of a two-stage pressure regulator on tank oxygen is recommended.


Rinse all parts with reagent water and allow to dry at room temperature or in an oven. Open tube ends to be ground and? Summary of Test Method 3. When oxidation is proceeding rapidly in such oils, values much higher d9943 2. Add the water using the sampling tube and the mL capacity syringe.


The subcommittee responsible for this method is investigating the application of alternative criteria for evaluation of lubricants using this satm apparatus. NOTE 4—As an alternative to using the sampling tube holder and sampling tube spacer, the sampling tube may be secured in position by taping or clamping to the oxygen delivery tube using a suitable adhesive tape or clamp.

Type Stainless Steel, 22 Gage 0. The sampling tube is taped or clamped to the oxygen delivery tube at a distance of approximately 25 mm 1 in. Rinse all the glassware with n-Heptane to remove d9443 of oil, asstm with a asstm detergent solution using a long-handled brush, and rinse thoroughly with tap water.

Clean the interiors of the test tubes, exteriors of the condensers, and both interiors and exteriors of the oxygen delivery tubes with cleaning reagent. An exception is where the oil is known to have a life shorter than h, the sampling is at the discretion of the operator. Box 70, Burlington, NJ A number in parentheses indicates the year of last reapproval.

Place the condenser over the oxygen delivery tube and test tube. Using this mandrel, the iron wire is wound on a thread of Safety features include low level liquid protection and over-temperature cut outs.

NOTE 2—Alternatively, suitably prepared catalyst coils may be purchased from a supplier. Any arrangement that leads to the coil con?

The mandrel shown in R943. Current edition approved August 10, In subsequent operations handle the catalyst wires with clean gloves cotton, rubber, or plastic to prevent contact with the skin. Rinse thoroughly with tap water until all cleaning solution is removed. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.


Rinse the tube with n-Heptane to remove traces of oil xstm any tenacious organic residues. Place the sampling aetm holder over the oxygen delivery tube. The test is considered to start at this point.

D — 02 All dimensions are in millimetres inches. NOTE 6—Under some circumstances, the level of water cannot be observed because of deposits or emulsion formation. The 35 litre oil bath can accept up to six sets of glassware.

If a ast window is included in the design, this viewing window shall be? The values given in parentheses are for information only. Measure the sample temperature by a thermometer positioned in the oxidation cell by a thermometer bracket, as in Fig.

Insert a stopper in the Luer-Lok? Methods of test for petroleum and its products. The turns of wire are evenly spaced, and two consecutive turns of the same wire are 3. The Seta Oxidation Bath is used for quantative analysis of the ast of oils and fuels to form sludge, acids and deposits when exposed to oxygen in the presence of metallic catalysts over extended periods.
