EXPLOSIVES OR THERMIC COMPOSITIONS (blasting F42D); MANUFACTURE THEREOF; USE OF SINGLE SUBSTANCES AS EXPLOSIVES (compounds in general C01, C07 or C08; {demolition agents based on cementitious or like materials C04B 41/0009})
Definition statement

This place covers:

Explosive compositions: compositions included are those containing both a fuel and sufficient oxidiser so that, upon initiation, they are capable of undergoing a chemical reaction of a relatively high rate of speed, resulting in the production of usable force for blasting, firearms, propelling missiles, or the like.

Thermic compositions; compositions included have

  • a consumable fuel component which consists of any element which is a metal, B, Si, Se or Te, or mixtures, compounds, or hydrides thereof; and
  • 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.

Compositions which are fuels for rocket engines and intended for reaction with an oxidant, excluding air, in order to provide thrust for motive power purposes.

Compositions used for affecting the explosion environment, e.g. for neutralising the poisonous gases of explosives or for cooling the explosion gases.

Methods or apparatus for preparing or treating, e.g. working-up, the compositions mentioned above, not otherwise provided for in the IPC.

Methods of using single substances as explosives.

Compositions mentioned above, defined by structure or arrangement of the components or products.

Relationships with other classification places

This subclass does not cover chemical compounds or their preparation as such, which subject matter is covered by classes C01 (inorganic chemistry), C07 (organic chemistry) and C08 (organic macromolecular compounds).

The use of explosive or thermic compositions for welding operations is classified in subclass B23K, the compositions as such used therefor are additionally classified in subclass C06B.

Special rules of classification

In this subclass, methods or apparatus for preparing or treating compositions are classified according to the particular components of the compositions.

In this subclass, with the exception of group C06B 21/00, in the absence of an indication to the contrary, a composition is classified in the last place that provides for an ingredient.

In this subclass, the words "based on", with reference to explosive compositions, refer to the explosive ingredient present in the largest proportion by weight

Methods or apparatus for preparing or treating compositions are classified accoding to the particular compositions.
