润滑脂和润滑油蒸发损失测定法
Application Summary AI generated
This standard specifies a test method for determining the evaporation loss of lubricating greases and oils under controlled high-temperature conditions. It is applied in the petroleum industry for quality control and performance evaluation of lubricants, particularly in applications where thermal stability is critical, such as automotive engines, industrial machinery, and aerospace components. The method helps assess the tendency of lubricants to lose volatile components during operation, which can affect their service life and lubrication effectiveness.
