Latest Products from This Supplier. Use of a pressure relief valve set at 70 kPa 10 psi is recommended. After 5 min, start the supply of air at a gage pressure of 20 kPa at the required temperature.

This apparatus measures the time for the entrained air content to fall to the relatively low value of 0.

ASTM D3427 Lubricating Oil Air Release Value Test Device (TP-0308)

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. A superscript epsilon e indicates an editorial change since the last revision or reapproval. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. This apparatus measures the time for the entrained air content to fall to the relatively low value of 0.

For ready comparison, the above statement is shown in DIN terms in Table 1. This is not what you are looking for? Current edition approved Nov.

A asfm sensor of at least equivalent performance is also suitable. Where air release value information is required for such oils, an air releasing time curve may be drawn. Last previous edition approved in as D — A new interlaboratory test program is planned.

Send This astn not what you are looking for? Interchanged parts may be used so long as the resultant test vessel conforms to the stated dimensions. However, entrained air can cause sponginess and lack of sensitivity of the control of turbine and hydraulic systems.

There is no known bias relative to the DIN 51 method. Air from a cylinder or a nonpulsating pump may be used.

ASTM D – 15 Standard Test Method for Air Release Properties of Hydrocarbon Based Oils

NOTE 11—The test may be run for a longer period of time by agreement between the laboratory and the customer. Balanced Reflux Boiling Point Tester. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high.

The significance of adtm test method has not been fully established. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high. If the loss causes any part of the sinker to be exposed, discontinue the test and repeat, using d342 sample that is 10 mL larger than previously used.

The apparatus adopts digital display temperature meter, control temperature with high accuracy.

Precision and Bias 7 9. NOTE 3—The application of thermal insulation to the pipework carrying the heated compressed air is recommended.

If the time is greater than 30 min, discontinue the test. Integrated design with big pressure gauge.
