CPC Definition - Subclass C10M
This place covers:
- Lubricant, i.e. a substance introduced to reduce friction between moving surfaces, which may be in the liquid, gaseous or solid form. The lubricating composition may be an emulsion, an aerosol, a grease, a dispersion of solid lubricants, a multi-layer coating or composite material.
- Use of at least one compound as a lubricant or in a lubricating composition.
- Working-up of used lubricants to recover useful products.
- Special method of preparation of lubricating oil compositions. Chemical after-treatment of components or the whole composition.
Lubricating compositions may have three types of essential ingredients: Base-Materials (main ingredient of the lubricating composition), Thickeners (used for preparing grease compositions) and Additives.
Additives are those chemicals used to enhance the performance characteristics of the base material where the additives are normally present in a minor amount of a fully formulated lubricating composition but can be present in a larger amount of an additive concentrate.
Lubricant compositions specially adapted for certain particular applications (e.g. mould release agents, well-drilling compositions, etc.) are classified in other subclasses – see the References sections below.
The use of known lubricants for relevant purposes is classified in the corresponding place, e.g. the use in harvesters or mowers is classified in A01D 69/12.
Subclass C10N is an indexing subclass associated with this subclass, and is for indexing features that are of interest in disclosures classified in this subclass, e.g. properties, uses or special modifications of lubricating compositions.

The specific C-Sets rule is located at only one place of the base symbol in the section "Special rules of classification" in the definition. If the C-Sets rule is applicable to all groups of a subclass, it is located at the subclass level only. If the same C-Sets rule is applicable to multiple groups or subgroups within the same subclass, the C-Sets rule is placed at the highest group or subgroup of the multiple groups.
