C10L1/00	7	Liquid carbonaceous fuels<br><br><u>NOTE</u><br><br>In groups C10L1/12 - C10L1/14, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, a compound is classified in the last appropriate place. <br>This Note corresponds to IPC Note (1) relating to C10L1/12 - C10L1/14.<br>If an additive is a mixture of compounds, classification is made for each compound of interest. This Note corresponds to IPC Note (2) relating to C10L1/12 - C10L1/14.<br>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 C10L1/24 and not in group C10L1/30. <br>This Note corresponds to IPC Note (3) relating to C10L1/12 - C10L1/14.<br>When classifying in this group, it is desirable to classify the individual additional components using Combination Sets with symbols chosen from groups C10L1/12 - C10L1/308.<br>Mixtures of additives are classified in the corresponding main group. Individual additives can be classified using Combination Sets according to the Note above.<br>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.<br>Documents classified until April 2003, have been classified with Combination Sets as explained in the Notes above, however using symbols chosen from groups C10L1/10 - C10L1/308.
