Your comments will receive careful consideration at a meeting of the responsible technical committee 1, which you may attend. The precision statement for this method was determined on steam turbine oils.

Oxidation Stability Test Apparatus, ASTM D, D, D, others

Unless otherwise indicated, it is intended that all reagents conform to the speci? To use this indicator, the lower end of the strip is set at the upper oil level when the test is started. Make temperature asstm only with new, undepleted, oil samples, and preferably with dummy cells used speci?

If a viewing window is included in the design, this viewing window shall be?

Then wipe with axtm absorbent cotton until all loose particles of metal and abrasive v943 been removed. If necessary, the coil may be stretched to give the required length Note 2 and Note 3. After each oil sample is taken, the indicator is moved to the new oil level before continuing the test. 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.

ASTM D – 17 Standard Test Method for Oxidation Characteristics of Inhibited Mineral Oils

Immerse the test tube in the heating bath. The use of a two-stage pressure regulator on tank oxygen is recommended. Insert the syringe sampling tube through the syringe sampling tube spacer, and into the sampling tube holder, as shown in Fig.

Before use it should be inspected to assure that no corrosion products or contaminating materials are present. The bottom of the sampling tube is positioned at 6 6 mm 6 6 0.

aztm NOTE 6—Under some circumstances, the level of water cannot be observed because of deposits or emulsion formation. The test is considered to start at this point. Add the water using the sampling tube and the mL capacity syringe.

Any arrangement that leads to the coil con? The number of test hours required for the oil to reach 2.

Oxidation Bath with Oxflo Controller

Originally published as D — 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 temperature of the bath is always higher than the sample temperature due to the cooling effect of the oxygen gas? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Place the sampling tube holder over the oxygen delivery tube.

Use of a very soft annealed steel wire may allow use of identical thread diameters for the two wires. Place the oxygen delivery tube with the coil into the test tube. 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.

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 size to 3 mL while holding the syringe vertically.

Therefore, use the applicable apparatus and techniques described in Practice D At that time, the state of severe oxidation of the oil, as indicated by the high acid number, is generally con? Glassware and catalysts must be ordered separately. Type Stainless Steel, 22 Gage 0.

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 A superscript epsilon e indicates an editorial change since the last revision or ashm.

When an actual test sample is used, remove the thermometer immediately after temperature measurement is complete. Hold the tube on an angle and gently slide the catalyst coil into the tube. 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 d9433. Soft copper wire of an equivalent grade may also be used.

Box 70, Burlington, NJ The temperature measurement system uses a PT probe to ensure long term temperature stability without routine maintenance or re-calibration.

When oxidation is proceeding rapidly in such oils, values much higher than 2. Similar wire conforming to BS is also satisfactory. Alternatively, sstm devices of equal or better accuracy may be used. Store glassware in a dry dust-free condition until ready to use.

For dark-colored oils, the use of potentiometric titration such as Test Method D to measure the end point may be advantageous.
