Add xstm water using the sampling tube and the mL capacity syringe. The oxidation test tube has a calibration line at mL. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Marking the upper oil level of the?

Similar wire conforming to BS is also satisfactory. Before using, the interior of the new tubing should be rinsed with n-Heptane and blown dry with air. ast

Alternatively, thin stainless steel wire may be used. Soft copper wire of an equivalent grade may also be used.

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 Shake the test oil sample thoroughly before taking a sample from the vial for titration. The 35 litre oil bath can accept up to six sets of glassware. Reagents and Materials 6. NOTE 9—The value 2. The bottom of the sampling tube is positioned at 6 6 mm 6 6 0. Make temperature measurements only with new, undepleted, oil samples, and preferably with dummy cells used speci?

If the wires are uneven at one end of the coil, position the coil so that this end is down. The correct level for water additions may, if desired, be indicated by a movable metal strip Astk.

Without interrupting the oxygen? NOTE 7—Test results by this method are greatly affected by differences in sampling procedure.

The test continues until the measured acid number of the oil is 2. The mandrel shown in Fig. Immediately after withdrawing the? The temperature measurement system uses a PT probe to ensure long term temperature stability without routine maintenance or re-calibration. The Luer-Lok connector is preferably of elastomeric material, such as poly? Warning— Compressed gas under high pressure. 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.

Open tube ends to be ground and? For overnight storage less than 24 h the coil may be stored in n-Heptane. Unless otherwise indicated, it is intended that all reagents conform to the speci? Slide the catalyst coil over the inlet of the oxygen delivery tube.

Alternatively, temperature—measuring devices of equal or better accuracy may be used. A number d934 parentheses indicates the year of last reapproval. D — 02 Dimensions are in millimetres inches.

All dimensions are in millimetres inches 1. Rinse thoroughly with tap water until all acid is removed. When oxidation is proceeding rapidly in such oils, values much higher than 2.
