and what are the standards used in finding out the appropriate hydraulic oil. I am currently working in maintenance department and my task is to find out which hydraulic oil is best for my machine
according to manufacturer's advice we have to use oil of 46 cSt at 40 degree celcius. I want to ask that what other parameters we have to consider in order to select hydraulic oil? @Bachir Achour
When choosing a hydraulic fluid, consider the following characteristics: viscosity, viscosity index, oxidation stability and wear resistance. These characteristics will determine how your fluid operates within your system. Fluid property testing is done in accordance with either American Society of Testing and Materials (ASTM) or other recognized standards organizations.
