Sch 6 para 7 Maximum permissible error
(1) In the case of a measuring system used to measure a quantity of liquid fuel— (a) above the minimum measured quantity of the measuring system, the maximum permissible error shall be determined in accordance with the following Table. + 4.8mL -2.4mL +8mL -4mL +16mL -8mL +24mL -12mL +40mL -20mL + 4.8% -2.4% + 8% -4% +16% -8% + 24% -12% + 40% -20% + 4.8mL -2.4mL + 8mL -4mL + 16mL -8mL + 24mL -12mL + 40mL -20mL + 1.2% -0.6% + 2% -1% + 4% -2% + 6% -3% + 10% -5% +12mL -6mL +20mL -10mL +40mL -20mL +60mL -30mL +100mL -50mL +0.6% -0.3% +1% -0.5% +2% -1% +3% -1.5% +5% -2.5% (b) equal to the minimum measured quantity of the measuring system, the maximum permissible error shall be determined in accordance with the following Table. +4.8mL -2.4mL +8mL -4mL +16mL -8mL +24mL -12mL +40mL -20mL + 4.8% -2.4% +8% -4% + 16% -8% +24% -12% +40% -20% + 9.6mL -4.8mL + 16mL -8mL + 32mL -16mL + 48mL -24mL + 80mL -40mL + 2.4% -1.2% + 4% -2% +8% -4% + 12% -6% + 20% -10% +24mL -12mL +40mL -20mL +80mL -40mL +120mL -60mL +200mL -100mL +1.2% -0.6% +2% -1% +4% -2% +6% -3% +10% -5% (2) 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. (3) 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.
