Paragraph 13 Minimum measured quantity
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 measurement is made to determine payments in respect of any customs or excise duty; or
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.
In sub-paragraph (1)(b), “frustrated delivery” means a delivery of liquid fuel from a road tanker which cannot be completed because—
there is insufficient space in the buyer's storage tank;
continuing the delivery would result in contamination of the liquid fuel or the mixing of different types of liquid fuel; or
a component of the meter measuring system breaks down.
