Organization: ASTM
Publication Date: 15 January 1995
Status: inactive
Page Count: 6
ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

This test method provides a calculation procedure for converting data obtained by Test Method D 972 to apparent vapor pressures and molecular weights. It has been demonstrated to be applicable to petroleum-based and synthetic ester lubricating oils,(Footnote 2) at temperatures of 395 to 535K (250 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.

The values stated in SI units are to be regarded as the standard. In cases in which materials, products, or equipment are available in inch-pound units only, SI units are omitted.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability or regulatory limitations prior to use. For specific warning statements, see 6.2, 7.1, 8.2, and Annex A2.
