For the purposes of regulation 21 the following expressions mean—

“aerial wheel” means tubes containing propellant charges and sparks, flame or noise-producing pyrotechnic composition (or all three), the tubes being fixed to a supporting structure, the principal effect of which is rotation and ascent, with emission of sparks and flames, producing a visual or aural effect (or both) in the air;

“banger” means a firework (other than a firework falling within regulation 21(1)(g)(i)(type of shot tube))—

• which comprises a non-metallic tube which contains pyrotechnic composition and has a fuse; and

• whose functioning principally involves report;

“battery” means an assembly which includes two or more fireworks of the same type;

“combination” means an assembly, other than a battery, which includes two or more fireworks;

“double banger” means a firework (other than a firework falling within regulation 21(1)(g)(i)(type of shot tube))—

• which comprises a non-metallic tube containing two portions of pyrotechnic composition connected by a delay fuse; and

• whose functioning principally involves one report, followed by ascent and a further report;

“flash banger” means a firework (other than a firework falling within regulation 21(1)(g)(i)(type of shot tube))—

• which comprises a non-metallic tube containing metal-based pyrotechnic composition; and

• whose functioning principally involves report and a flash of light;

“jumping cracker” means a paper tube containing black powder, folded back on itself several times and bound together, the principal effect of which is reports in succession with jumping motions;

“jumping ground spinner” means a non-metallic tube containing gas and sparks producing pyrotechnic composition, with or without whistling pyrotechnic composition, the principal effect of which is rotation on the ground frequently interrupted by a jumping motion and emission of sparks and flame, with or without an aural effect (other than report);

“mini-rocket” means a firework which is designed so that, on functioning, it propels itself into the air and which comprises a body or motor—

• which contains pyrotechnic composition or pyrotechnic units; and

• the outside diameter of which, at the point where the diameter is greatest, is less than 12 millimetres; or

• if equipped with a stick or sticks for the purposes of stabilising its flight—

  • where the firework is intended to be supplied singly, whose overall length (including the length of any such sticks) is less than 900 millimetres or (not including the length of any such sticks) is less than 195 millimetres; or

  • where the firework is intended to be supplied in a primary pack, whose overall length (including the length of any such stick or sticks) is less than 400 millimetres or (not including the length of any such stick or sticks) is less than 125 millimetres; or

  • where the firework is intended to be supplied in a selection pack, whose overall length (including the length or any such stick or sticks) is less than 300 millimetres; or

• if not equipped with a stick or sticks for the purposes of stabilising its flight—

  • whose overall length is less than 300 millimetres; and

  • is intended to be supplied singly or in a primary pack;

“primary pack” means a package of fireworks of the same type, all of which are either category 1, 2 or 3 fireworks, which is intended to be offered for retail sale as a single unit;

“selection pack” means a package of fireworks of more than one type intended to be offered for retail sale as a single unit;

“shot tube” means a tube containing propellant charge and a pyrotechnic unit, with or without a transmitting fuse, the principal effect of which is the ejection of the pyrotechnic unit producing a visual and/or aural effect in the air;

“spinner” means a tube containing pyrotechnic composition, with or without aerofoils attached, the principal effect of which is rotation and ascent with the emission of sparks, flames or both, with or without aural effect (other than report);

“wheel” means an assembly—

• which includes a tube or tubes containing pyrotechnic composition;

• which is designed to be attached to a support and to rotate about a fixed point or axis and which is provided with a means of attaching it securely to such a support so that it can so rotate; and

• whose functioning involves rotation around a fixed point and the emission of sparks and flames, with or without aural effect.
