Determination Of Cone Penetration Of Lubricating Grease
出版：Energy Institute (formerly Institute of Petroleum)
专家解读视频
Covers four procedures for measuring the consistency of lubricating greases by penetration of a standard cone. This method includes procedures for the measurement of unworked, worked, prolonged worked, and block penetrations. Penetrations up to 475 may be measured. Undisturbed penetrations are described in the Appendix. Unworked penetrations do not generally represent the consistency of greases in use as effectively as do worked penetrations. The latter are usually preferred for inspecting lubricating greases. Penetrations of block greases can be obtained on those products which are sufficiently hard to hold their shape. These greases generally have penetrations below 85.
