C06D MEANS FOR GENERATING SMOKE OR MIST; GAS-ATTACK COMPOSITIONS; GENERATION OF GAS FOR BLASTING OR PROPULSION (CHEMICAL PART) (fuels C10)
Description
C06D covers chemical compositions and formulations designed to produce smoke, mist, or gases through chemical reactions, excluding the mechanical or device aspects. This includes smoke-generating pyrotechnic mixtures for signaling, screening, or training purposes; tear gas and other riot control agents; and chemical formulations that liberate gases for blasting operations or propellant applications. The classification encompasses the chemical principles, ingredient combinations, and reaction mechanisms rather than the apparatus or delivery systems used to deploy these materials, which fall under related mechanical classes.
