(a) at least twice and, in the case of measuring equipment which is capable of delivery at different flow rates, this requirement shall be satisfied by one delivery at a low flow rate and one delivery at a flow rate that is as near as practicable to the measuring equipment's highest flow rate;

(b) so that the speed of operation in respect of any individual delivery is as uniform as practicable; and

(c) using local standards, working standards or testing equipment.".

(a) at the place where it is to be used; or

(b) at the place of its manufacture or assembly or at testing premises.

(b) "repeat indicating device" means a device which, using the interface which will be used when the measuring equipment is permanently installed, displays mandatory metrological indications;

(c) "control device" means a device using the interface which will be used when the measuring equipment is permanently installed which receives a call signal from the fuel dispenser and authorises delivery.".
