This standard specifies a method for the determination of the foaming characteristics of automotive lubricants and transmission fluids at 150 °C. The standard is used to assess the tendency of oils to foam at high temperature in applications such as high-speed gearing, high volume pumping and splash lubrication, where inadequate lubrication, cavitation, and loss of lubricant due to overflow, may lead to mechanical failure.
NOTE - Foaming characteristics of lubricating oils at temperatures up to 93,5 °C are determined by IP 146.
