Decent and beautiful design. 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.
Attach the wire to the beam and maintain a distance of 10 6 2 mm between the bottom of the sinker and the bottom of the test vessel. The apparatus is equiped with densimeter. NOTE 8—Oil misting occurs during d327. Find Similar Products By Category. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
Unless otherwise indicated, it is intended that all reagents conform to the speci? 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.
This test method was developed for hydrocarbon based oils. Balanced Reflux Boiling Point Tester. Attach the sinker to the beam of the density balance by means of the platinum wire so that the bottom of the sinker is 10 6 2 mm from the bottom of the test vessel.
This may result in an inability to maintain oil pressure particularly with centrifugal pumpsincomplete oil films in bearings and gears, and poor hydraulic system performance or failure.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The apparatus adopts digital display temperature meter, control temperature with high accuracy. Calculation of Density This can be implemented by recording the density at intervals, as required.
Aeration will switch the direction automatically 4. Typical questions asked about products Adtm this product support customization? Integrated design with big pressure gauge.
What is the warranty for the product? Send This is not what you are looking for? Care shall be taken to avoid restricting the air path with the thermometer bulb or any adapter used. If the time is greater than 30 min, discontinue the test. The component parts are described as follows: However, entrained air can cause sponginess and lack of sensitivity of the control of turbine and awtm systems. Not exactly what you want? This will be noted astj the time for the density to return to the initial?
This apparatus measures the time for the entrained air content to fall to the relatively low value of 0. This may take about 20 min. Wstm kipps apparatus China weighing apparatus Zstm melting point apparatus. There is no known bias relative to the DIN 51 method. The apparatus adopts the pressure regulator valve, pressure gauge displays. When the sinker has reached the test temperature, immerse it in the sample, taking care that no air bubbles cling to it.
This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address atm below.
However, the precision at these different temperatures is not known at present. The significance of this test method has not been fully established.
Originally approved in Box 70, Burlington, NJ The significance of this test method has not been fully established. Back pressure in excess of a gage pressure of 70 kPa 10 psi can be generated when the bath medium asfm pumped at the required rate; this can cause fracture of the glass or slippage of the hose connections.
No other units of measurement are included in this standard. NOTE 4—Use of water in the bath has been found to minimize electrostatic effects. China soxhlet apparatus China flash point apparatus China thermal conductivity apparatus. Set the circulating bath to give a specimen temperature within 0. Warning—The use of glass vessels with glass host?
Last previous edition approved in as D — A number in parentheses indicates the year of last reapproval. How do you ship the products? However, entrained air can cause sponginess and lack of sensitivity of the control of turbine and hydraulic systems.
Interchanged parts may be used so long as the resultant test vessel conforms to the stated dimensions. For ready comparison, the above statement is shown in DIN terms in Table 1. It may be used for some synthetic fluids; however, the precision statement applies only to hydrocarbon based oils.
This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high. 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.
