Definition statement
This subclass/group covers:

Chemical aspects of generating smoke or mist.

Compositions for gas-attacks ,e.g. toxic, irratating or debilitating gas-compositions..

Relationship between large subject matter areas

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

References relevant to classification in this subclass
This subclass/group does not cover:
Compositions used as biocides, pest repellants or attractants, or plant growth regulators
E.g.
Devices for generating heat, smoke, or fog in gardens, orchards, or forests, e.g. to prevent damage by frost
Informative references
Attention is drawn to the following places, which may be of interest for search:
Apparatus for generating gases
Inflatable occupant restraints or confinements characterized by the inflation source or means to control inflation fluid flow
Explosive compositions containing an oxidizer, fuels for rocket engines intended for reaction with an oxidant other than air
Fuels, e.g. natural or synthetic natural gas
Rocket-engine plants, i.e. plants carrying both fuel and oxidant therefor; Control thereof
Non chemical aspects of generating combustion products of high pressure of high velocity
Smoke-pot projectors
Smoke-producing projectiles, missiles or mines
Generation of smoke or mist (chemical part) (compositions used as biocides, pest repellants or attractants, or plant growth regulators A01N, e.g. A01N 25/18)
Definition statement
This subclass/group covers:

Generation of smoke or mist, e.g.

  • classic smokes are based on highly hygroscopic salts being acids and forming a water droplet fog with air humidity
  • Demisting compositions.
  • Weather modifying compositions such as making rain.
  • with expanded graphite particles
  • by combustion of pyrotechnic compositions comprising a chlorine donor (e.g. potassium chloride, sodium chloride, chlorinated rubber, condensed halogenated carbon compound) that will generate upon combustion abundants amounts of sublimable metal chlorides wich produce smoke
  • by combustion of pyrothechnic composition with sublimation/vaporization of an organic dye
  • by combustion of pyrotechnic composition comprising zinc oxide, ammonium cloride and polyvinyl chloride
  • by combustion of pyrotechnic smoke generating composition comprising red phosphorous
  • by incomplete combustion of aromatic compounds
Informative references
Attention is drawn to the following places, which may be of interest for search:
Compositions containing particulate metal, alloy, boron, silicon, selenium or tellurium with at least one oxygen supplying material which is either a metal oxide or a salt, organic or inorganic, capable of yielding a metal oxide
C05B33/00 to C05B33/14
Compositions containing free phosphorus or a binary compound of phosphorus, except with oxygen
Generation of pressure gas, e.g. for blasting cartridges, starting cartridges, rockets (explosive compositions containing an oxidizer, fuels for rocket engines intended for reaction with an oxidant other than air C06B)
Definition statement
This subclass/group covers:

Generation of pressure gas

Relationship between large subject matter areas

Explosive compositions containing an oxidizer, fuels for rocket engines intended for reaction with an oxidant other than air are classified in C06B.

The compositions in C06B are mainly classified according to their chemical composition. In C06B 47/00 monopropellants and bipropellants are classified according to their composition.

In C06D 5/08 and C06D 5/10, the compositions are classified according to their physical presence in the system like being a liquid or a solid and the compositions classified in those groups have to be suitable to produce a pressure gas.

by decompressing compressed, liquefied or solidified gases
Definition statement
This subclass/group covers:

CO2 - blasting.

by auto-decomposition of single substances
Definition statement
This subclass/group covers:

Catalysts for the auto-decomposition

For example decomposition of hydrogen peroxide, hydrazine.

Informative references
Attention is drawn to the following places, which may be of interest for search:
Compositions in which the components are separately stored until the moment of burning or explosion and one component contains hydrazine or a hydrazine derivative
