Introduced: September 1968
Description
C10M covers lubricating compositions and individual chemical substances used as lubricants or lubricating additives. This includes formulated oils, greases, and other lubricant products, as well as specific chemical compounds (such as base oils, viscosity modifiers, anti-wear agents, detergents, and corrosion inhibitors) employed in lubricating applications. The subclass addresses both the composition of finished lubricating products and the functional role of chemical ingredients within those compositions.

Glossary
Lubricant lubricants A lubricant is a composition, often in liquid form, that is introduced between two moving surfaces to reduce the friction and wear between them, usually by providing a protective film which allows the touching surfaces to be separated, thus lessening the friction between them. Lubricants are often organic liquids such as mineral oils (e.g. used as motor oils), but can also be non-liquid lubricants including grease, powders, dry graphite, polytetrafluoroethylene [PTFE], molybdenum disulphide, tungsten disulfide, etc. In addition to reducing friction and wear, lubricants can also transfer heat, carry away contaminants and debris, transfer power and prevent corrosion and rust. "Lubricant" or "lubricating composition" includes cutting oils, hydraulic fluids, metal drawing compositions, flushing oils, slushing oils, or the like.
