With the Petrotest device, OELCHECK tests the corrosion protection behavior of oils according to DIN ISO 7120. The test procedure was developed for mineral oils and other liquids such as synthetic oils. The test is used to assess the extent to which corrosive attack occurs on iron components in the presence of water and whether the corrosion-preventing additives can still reliably stop rust formation in used oils.
The oils tested are primarily inhibited mineral and synthetic oils, i.e. those with corrosion protection additives, such as those used in steam turbines, recirculating lubrication systems or hydraulic systems.
