V < 0.1L	4 × value in table (6-2), applied to 0.1 L
0.1 L ≤ V < 0.2 L	4 × value in table (6-2)
0.2 L < V < 0.4 L	2 × value in table (6-2), applied to 0.4 L
0.4 L ≤ V < 1 L	2 × value in table (6-2)
1 L ≤ V < 2 L	1 × value in table (6-2), applied to 2 L

Regardless of the measured quantity, the value of (MPE) is given as the higher of the following two values: a. The absolute value of the permissible error shown in Tables (2) and (3) of this Annex. b. The absolute value of the permissible error for the minimum measured quantity (Emin).
The following requirements apply if (Emin ≥ 2 Litres): a. 2 R ≤ Emin Where (R): is the smallest graduation period of the legal measuring instrument. b. Emin is given by the following relation: Emin = 2MMQ X A/100 Where (A): is the numerical value specified in row (A) of Table (2) of this Annex. c. The requirement (R2 ≤ Emin) applies to minimum measurands less than (2) litres, and (Emin) is twice the value specified in Table (3) of this Annex, corresponding to row (A) of Table (2) of this Annex.
The (MES) values provided in row (A) of Table (2) of this Annex apply to values transformed by overflow instruments.
The (PES) values for values transformed by these instruments are equal to the value (A-B) ±, where (A) and (B) represent the values specified in Table (2) of this Annex. The following parts of the measuring instruments can be inspected separately: a. Calculator: The positive or negative (MES) values for calculable liquid quantities are equal to (1/10) of the (PES) values defined in row (A) of Table (2) of this Annex. b. Associated legal measuring instruments: The maximum errors of the associated legal measuring instruments, according to the measuring systems used, are as indicated in Table (4) of this Annex.

Article (3-3) Maximum Permissible Effect of Disturbances:

The effect of electromagnetic disturbance on measuring systems must meet one of the following conditions: a. The change in the measurement result must not exceed the critical change value, as defined in Clause (3-3-2) of this Article. b. The measurement result that shows a transient change cannot be interpreted, recorded, or transmitted as a true measurement result. In case of stoppable systems, the presence of disturbance prevents any measurement from being conducted. c. If the change in the measurement result exceeds the critical change value, the device must be able to stop the flow and restore the measurement result that was present before the critical change value was exceeded.
The critical change value is the one that is greater than the result of dividing the maximum permissible error by 5 for the measured quantity, or Emin.

Article (3-4) Durability:

After the appropriate testing and considering the time period specified by the manufacturer, the difference in the measurement result after conducting durability testing must not exceed the value specified in Row (B) of Table (2) in this Annex when compared to the initial measurement results.

Article (3-5) Suitability:

The measurement results obtained by different meters with the same scale interval must not deviate by more than one scale interval. If the scale intervals are different, the deviation must not exceed the largest scale interval. In any case, when arranged for self-service, the scale intervals on the main measuring system and the self-service instrument should be the same, and the measurement results should not deviate from one another.
Altering the measured quantity during normal operating conditions must not be possible unless this change is clearly indicated.
The presence of air or gas mixed with the liquid, which cannot be easily detected, must not cause a measurement error change greater than: a. (0.5%) for non-potable liquids and liquids with a viscosity not exceeding (1 × 10⁻³) Pascal × second. b. (1%) for potable liquids and liquids with a viscosity greater than (1 × 10⁻³) Pascal × second. In case of the presence of gas pockets, the permissible change should not be less than (1%) of MMQ.
Instruments for direct sales: a. Measurement systems designed for direct sales must be equipped with a means to reset the reading to zero, and it must not be possible to alter the measured quantity. b. The device must be capable of retaining the measurement result until it is accepted by all concerned parties. c. Measurement systems for direct sales must be suitable and stoppable.
Fuel dispensers: a. The fuel dispenser must not be reset during measurement. b. A new measurement must not start until the reset is completed. c. When the measurement system is equipped with a price display unit, the price difference displayed on the price display unit and the price calculated from the price unit multiplied by the quantity sold must not exceed the price corresponding to Emin.

Article (3-6) Power Supply Failure:

The measurement system must be equipped with a power backup device that ensures all measurement functions are protected during a main power supply failure, or be equipped with a means to save and display results, and a means to stop the flow upon power failure.
