Table 6

Accuracy Class	Types of Measuring system
(1) However, Member States may require measuring systems of accuracy class 0.3 or 0.5 when used for the levying of duties on mineral oils when (un)loading ships and rail and road tankers.
Note: However, the manufacturer may specify a better accuracy for a certain type of measuring system
0.3	Measuring systems on pipeline
0.5	All measuring systems if not differently stated elsewhere in this Table, in particular: fuel dispensers (not for liquified gases), measuring system on road tankers for liquids of low viscosity (< 20 mPa.s), measuring systems for (un)loading ships and rail and road tankers(1), measuring systems for milk, measuring systems for refuelling aircraft.
1.0	Measuring system for liquefied gases under pressure measured at a temperature equal to or above -10°C Measuring systems normally in class 0.3 or 0.5 but used for liquids— whose temperature is less than -10°C or greater than 50°C; whose dynamic viscosity is higher than 1000 mPa.s; whose maximum volumetric flowrate is not higher than 20 L/h.
1.5	Measuring systems for liquefied carbon dioxide Measuring systems for liquefied gases under pressure measured at a temperature below –10ºC (other than cryogenic liquids)
2.5	Measuring systems for cryogenic liquids (temperature below –153ºC)
