(b) apparatus which includes one or more components designed to form part of the ignition apparatus of an internal combustion engine, and which is assembled for the purpose of testing or demonstrating the operation of one or more of those components, and which when used involves sudden changes of current in a high-voltage circuit.

(2) The requirement referred to in Regulation 5 shall be complied with in the case of any apparatus to which this Regulation applies, if the apparatus is to be used within the British Islands or the territorial waters adjacent thereto:—
