Notes

(1)

 This class covers also means for practice or training which may have aspects of simulation, although simulators are generally covered by class G 09.

(2)

 In this class, the following terms or expressions are used with the meanings indicated:
 

-

 "primer" effects the first explosive step in the sequence of explosion; [2]
 

-

 "percussion cap" means a primer which is struck to explode; [2]
 

-

 "igniter" effects the first spark-producing or heat-producing step but may not be explosive; [2]
 

-

 "firing-means" or "initiator" (used respectively in the arts of weaponry and blasting) means a device acting directly on the primer, which device may or may not form part of the fuze; [2]
 

-

 "detonator" or "detonator charge" means a charge used to amplify the explosion of the primer; [2]
 

-

 "fuze" means an assembly or mechanism which incorporates safety and arming means in order that the explosion can only take place under certain conditions; this assembly or mechanism determines also the moment (instantaneous or delayed) or the manner, e.g. impact, proximity, hydrostatic pressure, of the firing; [2]
 

-

 "ammunition" covers propulsive charge and projectile whether or not forming a single body, unless otherwise made clear; [2]
 

-

 "projectile", "missile" or "projectile or missile" means any body which is projected or propelled; [4]
 

-

 "guided missile" means projectile or missile which is guided during at least part of its trajectory; [4]
 

-

 "rocket" means projectile or missile which is self-propelled, during at least part of its trajectory, by a rocket engine, i.e. by a jet-propulsion engine carrying both fuel and oxidant therefor; [4]
 

-

 "fuse" or "fuse cord" means a continuous train of explosive enclosed in a usually flexible cord or cable for setting-off an explosive charge in the art of blasting. [5]
