Paragraph 7 Maximum permissible error
In the case of a measuring system used to measure a quantity of liquid fuel—
above the minimum measured quantity of the measuring system, the maximum permissible error shall be determined in accordance with the following Table.

But the maximum permissible error for a quantity above the minimum measured quantity of the measuring system shall not be less than the maximum permissible error for a quantity equal to the minimum measured quantity.
Where the measuring system falls within an accuracy class of 0.3, 0.5, 1.0, 1.5 or 2.5, it shall, for a quantity set out in column 1 of the relevant Table, operate within the maximum permissible error set out in column 2, 3, 4, 5 or 6 of that Table for that class and that quantity.
