The apparatus adopts digital display temperature meter, control temperature with high accuracy. No other units of measurement are included in this standard. Build-in air heater, safe and fast Technical parameters 1. The component parts are described as follows: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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. 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. Pt Platinum resistor 7. NOTE 3—The application of thermal insulation to the pipework zstm the heated compressed air is recommended. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.

Box 70, Burlington, NJ Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Back pressure in excess of a gage pressure of 70 kPa 10 psi can be generated when the bath medium is pumped at the required rate; this can cause fracture of the glass or slippage of the hose connections.

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.

The significance of this test method has not been asttm established. This may result in an inability to maintain oil pressure particularly with centrifugal pumpsincomplete oil? It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. Digital display temperature controller 4. NOTE 16—The precision statement was developed using 1. If the time is greater than 30 min, discontinue the test.

A new interlaboratory test program is planned. NOTE 1—This test method was developed for mineral based oils. Warning—Compressed gas under high pressure. This can be obtained by an additional bath, or by using a separate steam or electric heat exchanger. A coil of copper tubing immersed in the d347 bath see 6. This is not what you are looking for? This test method was developed for hydrocarbon based oils.
