A superscript epsilon e indicates an editorial change since the last revision or reapproval. Alternatively, thin stainless steel wire may be used. 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.
Add the water using the sampling tube and the mL capacity syringe. Warning— Compressed gas under high pressure. The test continues until the measured acid number of the oil astj 2. To use this indicator, the lower end of the strip is set at the upper oil level when the test is started.
Standard test method for oxidation characteristics of inhibited mineral oils. Place the condenser over the oxygen delivery tube and test tube.
After each oil sample is taken, the indicator is moved to the new oil d94 before continuing the test. It is important to strictly adhere to the procedure and schedule for sampling for acid number.
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, which you may attend.
Before use it should be inspected v943 assure that no corrosion products or contaminating materials are present. The correct level for water additions may, if desired, be indicated by a movable metal strip Fig. Similar wire conforming to BS is also satisfactory. Insert a stopper in the Luer-Lok? Type Stainless Steel, 22 Gage 0. Reagents and Materials 6. Preparation of Apparatus 8.
Current edition approved August 10, Safety features include low level liquid protection and over-temperature cut outs. 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.
Oxidation Bath with Oxflo Controller
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.
Test Method D is now available for sludge measurement. Glassware and catalysts must be ordered separately.
Several hours soaking in this manner often serves to loosen all adhering deposits except iron oxide. Soft copper wire of an astmm grade may also be used. A number in parentheses indicates the year of last reapproval. Measure the sample temperature by a thermometer positioned in the oxidation cell by a thermometer bracket, as in Fig.
Rinse thoroughly with tap water until all acid is removed. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
At that time, the state of severe oxidation of the oil, as indicated by the high acid number, is generally con?

The effect of such exposure on oil life has not been determined, nor has the method precision been determined by cooperative testing. 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. Therefore, use the applicable apparatus and techniques described in Practice D
