PART 4 U.K. LIQUID FUEL DELIVERED FROM ROAD TANKERS

Requirements for use for trade U.K.

9.  In this Part of this Schedule, “ measuring system” means a measuring system (other than one used in connection with the refuelling of aircraft, ships or hovercraft) which is used for the continuous and dynamic measurement in a quantity exceeding 100 litres or 100 kilograms of liquid fuel delivered from a road tanker other than—

(a) liquefied gases;

(b) lubricating oils;

(c) liquid fuels of a temperature below -153°C; or

(d) liquid fuels of a dynamic viscosity exceeding 100 millipascal seconds at 15°C.

10.  No person shall use for trade a measuring system unless— U.K.

(a) it is compliant with the essential requirements other than the provisions relating to maximum permissible errors;

(b) it is erected an installed so as to facilitate testing;

(c) it operates within the maximum permissible errors in paragraph 11; and

(d) the requirements of paragraphs 12 and 13 are complied with.

Maximum permissible error U.K.

11.—(1) A measuring system which falls within an accuracy class of 0.3, 0.5 or 1.0 must, when used to measure a quantity set out in column 1 of the following Table, operate within the maximum permissible error as set out in column 2, 3 or 4 of that Table for that class and that quantity.

	Accuracy class
	0.3	0.5	1.0
Column 1	Column 2	Column 3	Column 4
Quantity delivered	Maximum permissible error	Maximum permissible error	Maximum permissible error
MMQ to and including MMQ x 2	± 0.6% x MMQ	± 1% x MMQ	±2% x MMQ
˃MMQ x 2	± 0.3% x quantity delivered	± 0.5% x quantity delivered	± 1.0% x quantity delivered

(2) In the Table, “MMQ” means minimum measured quantity.

Manner of use U.K.

12.—(1) Where a measuring system is marked with—

(a) a temperature range, it must not be used for trade in temperatures outside that range; or

(b) a flowrate range, it must not be used for trade at a flowrate outside that range.

(2) A measuring system which bears a mark which signifies the manner and purpose of use must not be used for trade in a manner or for a purpose which does not accord with that marking.

(3) If a measuring system is adjusted, it must not be used for trade unless the calibration of the system is set as close to zero error as is practicable.

(4) A measuring system must not be used for trade unless it is fitted with a ticket printing mechanism which provides an individual printed ticket.

(5) A measuring system must not be used for trade in circumstances which are likely prematurely to degrade its metrological characteristics.

(6) A measuring system must not be used for trade unless the sales indicator—

(a) is set to zero before measurement of the liquid fuel commences;

(b) remains at zero until that fuel starts to emerge from the instrument;

(c) is not reset to zero during measurement of that fuel; and

(d) cannot be advanced by any means other than by the discharge of that fuel from the instrument and the proper operation of instrument.

(7) A measuring system must not be used in circumstances—

(a) which are likely prematurely to degrade its metrological characteristics; or

(b) in which it may be prevented from operating consistently or accurately.

Minimum measured quantity U.K.

13.—(1) A measuring system must not be used to measure quantities of liquid fuel delivered from a road tanker that are less than the minimum measured quantity but this paragraph does not apply where—

(a) a measurement is made to determine payments in respect of any customs or excise duty; or

(b) a frustrated delivery has taken place and all reasonable precautions have been taken and all due diligence has been exercised to avoid a frustrated delivery.

(2) In sub-paragraph (1)(b), “frustrated delivery” means a delivery of liquid fuel from a road tanker which cannot be completed because—

(a) there is insufficient space in the buyer's storage tank;

(b) continuing the delivery would result in contamination of the liquid fuel or the mixing of different types of liquid fuel; or

(c) a component of the meter measuring system breaks down.
