Chemistry Laboratory Department
Main activities of the Chemical Laboratory Department:
- Performs tests and analyzes of the purity of hydraulic fluids used in aircraft maintenance
- Performs tests of lubricating oils, hydraulic fluids and oils used as fluids in cooling systems
- Performs assessment of the suitability of lubricating fluids for specific applications
- Performs analyzes of solutions and baths at the surface treatment workshop
