Foaming Characteristics
of Lubricating Oils

ASTM D892
DIN 51566
IP 146

Foaming Characteristics of Lubricating Oils.
This test method covers the determination of the foaming characteristics of lubricating oils at 24°C and 93.5°C. Means of empirically rating the foaming tendency and the stability of the foam are described.
