Your comments e3427 invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The apparatus adopts the pressure regulator valve, pressure gauge displays. Set the compressed air temperature to within 0.
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 16—The precision statement was developed using 1. Set the circulating bath to give a specimen temperature within 0.
Use of a pressure relief valve set at 70 kPa 10 psi is recommended. Your comments will receive careful consideration at a meeting qstm the responsible technical committee,1 which you may attend. Digital timer alarm, easy to operate.
The significance of this test method has not been fully established. If the residence time in the reservoir is too short to allow the air bubbles to rise to the oil surface, a mixture of air and oil will circulate through the lubricating oil system.
NOTE 8—Oil misting occurs during blowing. A coil of copper tubing immersed in the circulating bath see 6. Typical questions asked about products Does this product support customization?

ASTM D – 15 Standard Test Method for Air Release Properties of Hydrocarbon Based Oils
The two parts of each test vessel should be marked and preferably used as a pair. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
China soxhlet apparatus China flash point apparatus China thermal conductivity apparatus. Link to Active This link will always route to the current Active version of the standard. This apparatus measures the time for the entrained air content to fall to the relatively low value of 0.
However, entrained air can cause sponginess and lack of sensitivity of the control of turbine and hydraulic systems. A number in parentheses indicates the year of last reapproval.
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.
ASTM D3427 Lubricating Oil Air Release Value Test Device (TP-0308)
The significance of this test method has not been fully established. Last previous edition approved in as D — If the residence time in the reservoir is too short to allow the air bubbles to rise to the oil surface, a mixture of air and oil will circulate through the d34227 oil system.
