Petroleum products and lubricants — Rheological properties of lubricating greases — Determination of...
This document specifies a procedure to determine the consistency of a metal-saponified lubricating grease by an oscillatory rheometer.
This test method is applicable for fresh, as well as used, lubricating greases where only small quantities of the grease are present and the worked penetration that is usually used cannot be determined due to the small quantity.
The determined calibration is only…
