This International Standard specifies a method for the determination of the dropping point of lubricating grease over a wide temperature range. NOTES — 1 The dropping point is useful as an aid to identification of lubricating grease as to type, and as a bench mark for quality control. The results should be considered to have only limited significance with respect to service performance because dropping point is a static test. 2 Cooperative testing indicates that, in general, dropping points determined according to this International Standard and to ISO 2176 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 the test method used is advisable.
