Any arrangement that leads to the coil con? Place the condenser over the oxygen delivery tube and test tube. Adjust the rate of? NOTE 1—Furthermore, in the course of testing a lubricant by this method, other signs of deterioration, such as sludge formation or catalyst coil corrosion, may appear that are not re?

In subsequent operations handle the catalyst wires with clean gloves cotton, rubber, or plastic to prevent contact with the skin. 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.

Oxidation Bath with Oxflo Controller

Marking the upper oil level of the? Add a desiccant bag that has been folded lengthwise to? The Luer-Lok connector is preferably of elastomeric material, such as poly? Rinse all parts with reagent water and allow to dry at room temperature or in an oven. 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.

Insert the syringe sampling tube through the syringe sampling tube spacer, and into the sampling tube holder, as shown in Fig. Rinse all the glassware with n-Heptane to remove traces of oil, wash with a hot detergent solution using a long-handled brush, and rinse thoroughly with tap water. Slide the catalyst coil over the inlet of the oxygen delivery tube.


The smaller diameter is to allow for springback of the steel wire after winding, so as to give The overall length of the?

As the test proceeds and water evaporates to cause the oil level to fall, sufficient makeup water is added, particularly just before oil samples are taken, to return the oil level to the level marked by the indicator strip. The 35 litre oil bath can accept up to six sets of glassware.

Your comments will receive careful consideration at a meeting of the responsible technical committee 1, which you may attend. The subcommittee responsible for this method is investigating the application of alternative criteria for evaluation of lubricants using this test apparatus.

Copyright Stanhope—Seta Limited Open tube ends to be ground and? Box 70, Burlington, NJ If these steels are not available, other equivalent steels d934 be used, provided they are found to be satisfactory in comparative tests using Test Method D The thermometer is held in the bracket by two?

Determination of the oxidation stability of middle-distillate fuels.

The oxidation test tube has a calibration line at mL. Oxidation Bath with Oxflo Controller Part Number The Seta Oxidation Bath is used for quantative analysis of the tendency of oils and fuels to form sludge, acids and deposits when exposed to oxygen in the presence of metallic catalysts over extended periods.

Methods of test for petroleum and its products. The use of a two-stage pressure regulator on tank oxygen is recommended. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.


Type Stainless Steel, 22 Gage 0. Rinse thoroughly with tap water until all cleaning solution is removed.

Current edition approved August 10, The precision statement for this method was determined on steam turbine oils. When an actual test sample is used, remove the thermometer immediately after temperature measurement is complete. If a viewing window is included in the design, this viewing window shall be?

Adjust the heating bath liquid level so that the tube is immersed in the liquid to a depth of 6 10 mm. Before use it should be inspected to assure that no corrosion products or contaminating materials are present.

Summary of Test Method 3. Therefore, use the applicable apparatus and techniques described in Practice D Standard test method for determination of the sludging and corrosion tendencies of inhibited mineral oils.

If more than two results are obtained by one or both of the laboratories, reproducibility can be calculated as indicated astj 4.

Glassware and catalysts must be ordered separately. Standard test method for oxidation characteristics of inhibited mineral oils.

Several hours soaking in this manner often serves to loosen all adhering deposits except iron oxide. If necessary, the coil may be stretched to give the required asrm Note 2 and Note 3. Replace the sampling tube stopper. Gas reduces oxygen available for breathing.
