Note(s)

  1. This class covers also means for practice and training which may have aspects of simulation, e.g. in apparatus for so-called "military games", although simulators are generally covered by class G09.  [4]
  2. In this class, the following terms or expressions are used with the meanings indicated:
    • "smallarm" means a firearm which is generally held with one or both hands for firing, but this term also includes a light machine-gun which may be supported on a tripod or the like during firing;  [5]
    • "gun" means any weapon having a barrel and a trigger or firing mechanism for projecting a missile; it may be a piece of ordnance or a smallarm. It may use combustible or explosive propellant charges, air pressure, electromagnetism or other propulsive forces;  [5]
    • "revolver-type gun" means a gun having a revolving drum magazine, the chambers of which are used successively as firing chamber;  [5]
    • "revolver" means a revolver-type pistol;  [5]
    • "semi-automatic firearm" means a firearm from which one shot is fired after actuation of the trigger and which then returns to a condition for firing a subsequent shot upon renewed actuation of the trigger;
    • "automatic firearm" means a firearm which will continue firing so long as the initial firing pressure is maintained on the trigger;
    • "sighting" means bringing into visual coincidence a direction defined by a so-called "sighting" device with the direction of a target;
    • "aiming" means bringing a weapon to a direction differing from the sighting direction by corrections in order that the projectile may hit the target;
    • "laying" means setting a weapon in the correct position for hitting a target.
  3. Attention is drawn to the definitions of "projectile", "missile" and "rocket" given in Note (2) following the title of class F42.  [4]
