DROP POINT APPARATUS FOR GREASE-ASTM D566, IP132- FULLY AUTOMATIC

Compliance with following International Standards:

ASTM D566, IP 132, ISO 2176

Purpose:

This test method covers the determination of the dropping point of lubricating grease. This test method is not recommended for use at bath temperatures above 288°C.

Significance & Use:

In general, the dropping point is the temperature at which the grease passes from a semisolid to a liquid state under the conditions of test. This change in state is typical of greases containing as thickeners soaps of conventional types. This test method is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control.
