Your comments asttm receive careful consideration at a meeting of the responsible technical committee, which you may attend. NOTE 12—For some applications, the shape of the air release time curve may be required. Other test methods for example, Test Method D have demonstrated acceptable, statistically equivalent results when Nochromix or Micro is used to replace sulfuric chromic acid for cleaning.

No other units of measurement are included in this standard. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. Ramsbottom Carbon Residue Tester Electric furnace method. For ready comparison, the above statement is shown in DIN terms in Table 1.

This will be noted if the time for the density to return to the initial? Pt Platinum resistor 7. Zstm 11—The test may be run for a longer period of time by agreement between the laboratory and the customer. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

NOTE 4—Use of water in the bath has been found to minimize electrostatic effects. The temperature of the air shall be measured by a thermometer located as close as possible to the testing vessel asgm meeting the speci? Care c3427 be taken to avoid restricting the air path with the thermometer bulb or any adapter used. If the loss causes any part of the sinker to be exposed, discontinue the test and repeat, using a sample that is 10 mL larger than previously used. Summary of Test Method 4.

If the time is greater than 30 min, discontinue the test. There is no known bias relative to the DIN 51 method. 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 responsibility. It awtm be used for some synthetic fluids; however, the precision statement applies only to hydrocarbon based oils. Boiling Point of Engine Coolants Tester. Where air release value information is required for such oils, an air releasing time curve may be drawn.
