ActiveDetermination of foaming characteristics of lubricating oils
润滑油泡沫特性测定法
Application Summary AI generated
This standard specifies a laboratory test method for measuring the foaming tendency and foam stability of lubricating oils under controlled conditions. It is applied in the petroleum industry for quality control and formulation development of engine oils, hydraulic fluids, and industrial lubricants. The test helps ensure that lubricants will not generate excessive foam during operation, which can impair lubrication, cause cavitation, or lead to equipment failure.
