C10L - Definition fr

Definition statement

This subclass covers:

Compositions which react chemically, usually with oxygen in air, to produce heat in controllable amounts or which are dispersed in air for explosive combustion in an engine or which produce light along with heat upon combustion, i.e. liquid carbonaceous fuels, gaseous fuels, natural gas, synthetic natural gas, liquefied petroleum gas, solid fuels and fuels produced by solidifying fuels

Treatment of fuels to improve their combustion

Use of additives to fuels or fires for particular purposes, e.g. for reducing smoke development, for minimising corrosion or incrustation, for facilitating soot removal or for improving the octane number or the low temperature properties of the fuel

Fire-lighters, i.e. easily-combustible compositions or shaped products which are designed to initiate the combustion of a larger body of fuel and methods or apparatus for their manufacture

References relevant to classification in this subclass

This subclass does not cover:
