1.1”This test method covers a calculation procedure for converting data obtained by Test Method D972 to apparent vapor pressures and molecular weights. It has been demonstrated to be applicable to petroleum-based and synthetic ester lubricating oils,2 at temperatures of 395”’K to 535”’K (250””’F to 500””’F). However, its applicability to lubricating greases has not been established.
Note 1:”Most lubricants boil over a fairly wide temperature range, a fact recognized in discussion of their vapor pressures. For example, the apparent vapor pressure over the range 0”’% to 0.1”’% evaporated may be as much as 100 times that over the range 4.9”’% to 5.0”’% evaporated.
