NOTE

In subclass C10L it is desirable to give indexing codes for information about components of solid, liquid and gaseous fuels or firelighters, their additives and constituents and their preparation and use. The indexing codes are taken from C10L 2200/00 to C10L 2290/60

NOTE
-
In groups C10L 1/12 to C10L 1/30
{
C10L 1/308
}
, in the absence of an indication to the contrary, a compound is always classified in the last appropriate place.

A metal salt or an ammonium salt of a compound is classified as that compound, e.g. a chromium sulfonate is classified as a sulfonate in group C10L 1/24 and not in group C10L 1/30 .

When classifying in this group, it is desirable to classify the individual additional components using Combination Sets with symbols chosen from groups C10L 1/12 to C10L 1/308

Mixtures of additives are classified in the corresponding main group. Individual additives can be classified using Combination Sets according to the Note above

When several alternatives for the same individual additive are mentioned, e.g. as a Markush-formula, classification may be done in the corresponding main group only, the alternatives being classified using Combination Sets, according to the Note above.

Documents classified until April 2003, have been classified with Combination Sets as explained in the Notes above, however using symbols chosen from groups C10L 1/10 to C10L 1/308 .
