Several hours soaking in this manner often serves to loosen all adhering deposits except iron oxide. Rinse thoroughly with tap water until all cleaning solution is removed. NOTE 10—Beyond 10 h, oil removal causes the metal catalyst coil to be exposed to the atmosphere.

If more than two results are obtained by one or both atm the laboratories, reproducibility can be calculated as indicated in 4. This can be accomplished as follows. Place the sampling tube holder over the oxygen delivery tube. The smaller diameter is to allow for springback of the steel wire after winding, so as to give If a viewing window is included in the design, this viewing window shall be?

Measure the sample temperature by a thermometer positioned in the oxidation cell by a thermometer bracket, as in Fig. The use of a two-stage pressure regulator on tank oxygen is recommended. Connect the condenser to the cooling water. NOTE 7—Test results by this method are greatly affected by differences in sampling procedure.

Unless otherwise indicated, it is intended that all reagents conform to the speci? Add a desiccant bag that has been folded lengthwise to?

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. The test is considered to start at this point. The precision statement for this method was determined on steam turbine oils. Therefore, use the applicable apparatus and techniques asm in Practice D Check the temperature in this way in various parts of a multiple-cell bath to verify uniformity of temperature control.

Alternatively, thin stainless steel wire may be used. NOTE 6—Under some circumstances, the level of water cannot be observed because of deposits or emulsion formation. Before use it should be inspected to assure that no corrosion products or contaminating materials are present.

Rinse all parts with reagent water and allow to dry at room temperature or in an oven. If deposits still adhere to the glassware, a method that has been found useful is to? 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. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Rinse the tube with n-Heptane to remove traces of oil and any tenacious organic residues. Your comments will receive careful consideration at a meeting of the responsible technical committee1, which you may attend.

NOTE 9—The value 2. See detailed specifications Available accessories Request a quotation More products in this subcategory. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

When oxidation is proceeding rapidly in such oils, values much higher than 2. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. When an actual test sample is used, remove the thermometer immediately after temperature measurement is complete.

Oxidation Bath with Oxflo Controller

The temperature of the bath is always higher than the sample temperature due to the cooling effect of the oxygen gas?

Using this mandrel, the iron wire is wound on a thread of Insert the syringe sampling tube through the syringe sampling tube spacer, and into the sampling tube holder, as shown in Fig. Clean the interiors of the test tubes, exteriors of the condensers, and both interiors and exteriors of the oxygen delivery tubes with cleaning reagent.

Place the oxygen delivery tube with the coil into the test tube.

Repeat the rinsing procedure with n-Heptane and blow dry with air or nitrogen. If these steels are not available, other equivalent steels may be used, provided they are found to be satisfactory in comparative tests using Test Method D Rinse thoroughly with tap water until all acid is removed. Current edition approved August 10, 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.
