This may take about 20 min. 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. Request a custom order and have something just for you!

Work Item s – proposed revisions of this standard. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air.

NOTE 12—For some applications, the shape of the air release time curve may be required. A coil of copper tubing immersed in the circulating bath see 6. Warning—The use of glass vessels with glass host?

The significance of this test method has not been fully established. Digital display temperature controller. 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.

If the astmm 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.
