2. Maximum permissible error (MPEs)
Table 1 Class 1,5 1,0 Q_(min) ≤ Q < Q_(t) 3 % 2 % Q_(t) ≤ Q ≤ Q_(max) 1,5 % 1 % The gas meter shall not exploit the MPEs or systematically favour any party. 2.2. For a gas meter with temperature conversion, which only indicates the converted volume, the MPE of the meter is increased by 0,5 % in a range of 30 °C extending symmetrically around the temperature specified by the manufacturer that lies between 15 °C and 25 °C. Outside this range, an additional increase of 0,5 % is permitted in each interval of 10 °C.
