Note(s)

  1. This subclass covers:
    • compositions which are:
      1. explosive: compositions included are those containing both a fuel and sufficient oxidiser so that, upon initiation, they are capable of undergoing a chemical change of a relatively high rate of speed, resulting in the production of usable force for blasting, firearms, propelling missiles, or the like; [2]
      2. thermic: compositions included have (i) a consumable fuel component which consists of any element which is a metal, B, Si, Se or Te, or mixtures, intercompounds, or hydrides thereof; and (ii) in combination an oxidant component which is either a metal oxide or a salt (organic or inorganic) capable of yielding a metal oxide on decomposition; [2]
      3. fuels for rocket engines and intended for reaction with an oxidant, excluding air, in order to provide thrust for motive power purposes; [2]
      4. for use in affecting the explosion environment, e.g. for neutralising the poisonous gases of explosives, for cooling the explosion gases, or the like; [2]
    • methods or apparatus for preparing or treating such compositions not otherwise provided for; [2]
    • methods of using single substances as explosives. [2]
  2. In this subclass, the following term is used with the meaning indicated:
    • "nitrated" covers compounds having a nitro group or a nitrate ester group. [2]
  3. Methods or apparatus for preparing or treating such compositions are classified according to the particular components of the compositions. [2]
