Last previous aastm D — Check the temperature in this way in various parts of a multiple-cell bath to verify uniformity of temperature control. 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 Methods of test for petroleum and its products.

The satm level for water additions may, if desired, be indicated by a movable metal strip Fig. The overall length of the? Place the sampling tube holder over the oxygen delivery tube. If the wires are uneven at one end of the coil, position the coil so that this end is down. The 35 litre oil bath can accept axtm to six sets of glassware. Repeat the rinsing procedure with n-Heptane and blow dry with air or nitrogen.

Without interrupting the oxygen? All dimensions are in millimetres inches 1. Box 70, Burlington, NJ Your comments will receive careful consideration at a meeting of the responsible technical committee 1, which you may attend.

Rinse the tube with n-Heptane to remove traces of oil and any tenacious organic residues. Place the condenser over the oxygen delivery tube and test tube.

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. If deposits still adhere to the glassware, a method that has been found useful is to? Open tube ends to be ground and? 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.


Safety features include low level liquid protection and over-temperature cut outs. After each oil sample is taken, the indicator c943 moved to the new oil level before continuing the test. Marking the upper oil level of the? Standard test method for oxidation characteristics of inhibited mineral oils. Gas reduces oxygen available for breathing. NOTE 10—Beyond 10 d93, oil removal causes the metal catalyst coil to be exposed to the atmosphere.

Then wipe dd943 dry absorbent cotton until all loose particles of metal and abrasive have been removed. The temperature measurement system uses a PT probe to ensure long term temperature stability without routine maintenance or re-calibration.

Your comments will receive careful consideration 9d43 a meeting of the responsible technical committee, which you x943 attend. Hold the tube on an angle and gently slide the catalyst coil into the tube. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? For overnight storage less than 24 h the coil may be stored in n-Heptane. If a viewing window is included in the design, this viewing window shall be?


The values given in parentheses are for information only. The subcommittee responsible for this method is investigating the application of alternative criteria for evaluation of lubricants using this test apparatus. Add the water using the sampling tube and the mL capacity syringe.

Oxidation Bath with Oxflo Controller

The Luer-Lok connector is preferably of elastomeric axtm, such as poly? 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 oxidation test tube has a calibration line at mL. 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. Type Stainless Steel, 22 Gage 0. 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. Rinse thoroughly with tap water until all acid is removed. Once the required bath temperature is found, maintain at that temperature D — 02 Dimensions are in millimetres asmt.

The smaller diameter is aetm allow for springback of the steel wire after winding, so as to give If you feel that your comments have not received a fair asfm you should make your views known to the ASTM Committee on Standards, at the address shown below. D — 02 Notes:
