Standard Test Method for Dropping Point of Lubricating Grease Over Wide Temperature Range

Importancia y uso:

5.1 The dropping point is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control. The results are to be considered to have only limited significance with respect to service performance of conventional soap thickeners because dropping point is a static test. Above 200 °C, the dropping point has no correlation with the maximum upper operating temperature of the grease.

5.2 Historical cooperative testing4 on conventional soap-thickened greases indicated ( RR:D02-1164) that, in general, dropping points by Test Method D2265 and Test Method D566 were in agreement up to 200 °C. In cases where results differ, there is no known significance. However, agreement between the manufacturer and purchaser as to test method used is advisable.
