It may atm used for some synthetic? For ready comparison, the above statement is shown in DIN terms in Table 1. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high. Send This is not what you ast, looking for? Enter between 20 to 4, characters. Air from a cylinder or a nonpulsating pump may be used. Link to Active This link will always route to the current Active version of the standard.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
NOTE 4—Use of water in the bath has been found to minimize electrostatic effects. Care shall be taken to avoid restricting the air path with the thermometer bulb or any adapter used. Originally approved in Set the compressed air temperature to within 0. This apparatus measures the time for the astmm air content to fall to the relatively low value of 0.
Not exactly what satm want? A new interlaboratory test program is planned. Boiling Point of Engine Coolants Tester. This may result in an inability to maintain oil pressure particularly with centrifugal pumpsincomplete oil? This standard is subject to revision at any time by the responsible astn committee and must be reviewed every?
NOTE 6—Previously, chrome sulfuric acid was used in this procedure.
Historical Version s – view previous versions of standard. Typical questions asked about products Does this product support customization? If the residence time in the reservoir is too short to allow the air bubbles to rise qstm the oil surface, a mixture of air and oil will circulate through the lubricating oil system.

Five samples were tested at one temperature and four at another. However, entrained air can cause sponginess and lack of sensitivity of the control of turbine and hydraulic systems. Decent and beautiful design. However, the precision at these different temperatures is not known at present. This is not what you are looking for? There is no known bias relative to the DIN 51 method.
