The following notes are meant to assist in the use of this part of the classification scheme. They must not be read as modifying in any way the elaborations.
Section C covers:
pure chemistry, which covers inorganic compounds, organic compounds, macromolecular compounds, and their methods of preparation;
applied chemistry, which covers compositions containing the above compounds, such as: glass, ceramics, fertilisers, plastics compositions, paints, products of the petroleum industry. It also covers certain compositions on account of their having particular properties rendering them suitable for certain purposes, as in the case of explosives, dyestuffs, adhesives, lubricants, and detergents;
certain marginal industries, such as the manufacture of coke and of solid or gaseous fuels, the production and refining of oils, fats and waxes, the fermentation industry (e.g., brewing and wine-making), the sugar industry;
certain operations or treatments, which are either purely mechanical, e.g., the mechanical treatment of leather and skins, or partly mechanical, e.g., the treatment of water or the prevention of corrosion in general;
metallurgy, ferrous or non-ferrous alloys.
-
In the case of operations, treatments, products or articles having both a chemical and a non-chemical part or aspect, the general rule is that the chemical part or aspect is covered by section C.
In some of these cases, the chemical part or aspect brings with it a non-chemical one, even though purely mechanical, because this latter aspect either is essential to the operation or treatment or constitutes an important element thereof. It has seemed, in fact, more logical not to dissociate the different parts or aspects of a coherent whole. This is the case for applied chemistry and for the industries, operations and treatments mentioned in Notes (1)(c), (d) and (e). For example, furnaces peculiar to the manufacture of glass are covered by class Fulltext... Hierarchy... Expanded...C03 and not by class Fulltext... Hierarchy... Expanded...F27.
There are, however, some exceptions in which the mechanical (or non-chemical) aspect carries with it the chemical aspect, for example:
Photographic materials and processes, in class Fulltext... Hierarchy... Expanded...G03, and, generally, the chemical treatment of textiles and the production of cellulose or paper, in section D.
In still other cases, the pure chemical aspect is covered by section C and the applied chemical aspect by another section, such as A, B or F, e.g., the use of a substance or composition for:
When the chemical and mechanical aspects are so closely interlocked that a neat and simple division is not possible, or when certain mechanical processes follow as a natural or logical continuation of a chemical treatment, section C may cover, in addition to the chemical aspect, a part only of the mechanical aspect, e.g., after-treatment of artificial stone, covered by class Fulltext... Hierarchy... Expanded...C04. In this latter case, a note or a reference is usually given to make the position clear, even if sometimes the division is rather arbitrary.
In this subclass, the following terms or expressions are used with the meanings indicated:
"use of materials for coating compositions" means the use of known or new polymers or products;
"rubber" includes:
natural or conjugated diene rubbers;
rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for coating compositions based on such macromolecular compounds);
"based on" is defined by means of Note (3), below;
"filling pastes" means materials used to fill up the holes or cavities of a substrate in order to smooth its surface prior to coating. [5]
In this subclass, coating compositions, containing specific organic macromolecular substances are classified only according to the macromolecular substance, non-macromolecular substances not being taken into account.
Aspects relating to the physical nature of the coating compositions or to the effects produced, as defined in group Fulltext... Hierarchy... Expanded...C09D 5/00, if clearly and explicitly stated, are also classified in this subclass.
Coating compositions characterised by other features, e.g. additives, are classified in group Fulltext... Hierarchy... Expanded...C09D 7/00, unless the macromolecular constituent is specified. [5]
In this subclass, coating compositions comprising two or more macromolecular constituents are classified according to the macromolecular constituent or constituents present in the highest proportion, i.e. the constituent on which the composition is based. If the composition is based on two or more constituents, present in equal proportions, the composition is classified according to each of these constituents.
In groups Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...C09D 101/00-C09D 201/00, it is desirable to add the indexing codes relating to additional macromolecular constituents of the coating composition. The indexing codes, which are chosen from the said groups, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked.
Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code. [6]
