1: A sulfur limit of 1.5% m/m will apply in SOx Emission Control Areas designated by the International Maritime Organization, when its relevant Protocol comes into force. There may be local variations.
2: The Fuel shall be free of ULO.
A Fuel is considered to be free of ULO if one or more of the elements are below the limits.All three elements shall exceed the limits before deemed to contain ULO.
