Significance and Use
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 because dropping point is a static test.
Cooperative testing indicates that, in general, dropping points by Test Method D 2265 and Test Method D 566 are in agreement up to 260°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.
