F16N - Definition 
Definition statement
This subclass covers:
Constructional modifications of parts of machines orapparatus for the purposes of lubrication.
Devices for supplying lubricant, e.g. oil or grease, from a stationary or movable reservoir to the machine or member to be lubricated, or for supplying lubricant by manual action or by a hand-positioned nozzle with lubricant under pressure.
Lubricating-pumps.
Lubrication using substances other than oil or grease.
Lubrication characterised by the use of particular lubricants in particular apparatus or conditions.
Lubrication of apparatus working in extreme conditions.
Details of lubricators or lubrication systems, e.g reservoirs, conduits, check valves, distributing equipment, collecting or draining lubricant, cleaning.
Safety devices for indication or detection of undesired conditions, or use of devices responsive to conditions in lubricating arrangements or systems.
Care of lubricants, e.g. storage, transfer.
Conditioning lubricants, e.g. by heating, cooling, filtering, diluting.
Relationship between large subject matter areas
F16N is the general or function-oriented subclass for lubrication subject-matter, but there are many application-oriented places in the Classification where subject-matter for specially-adapted forms of lubrication can be found see the references below. Lubrication specially adapted to machines orapparatus provided for in a single other class is covered by the relevant class for that machine orapparatus.

Glossary of terms
In this subclass, the following terms or expressions are used with the meaning indicated:
| Lubrication | Apparatus, arrangements or methods for introducing or applying a thin layer of a discrete lubricant between two or more relatively-moving adjacent solid surfaces of a device or apparatus, for the specific purpose of reducing friction, heat or wear between the adjacent surfaces. |
| Lubricant | Any fluid (e.g. water, oil), fluent material (e.g. particulate graphite), semi-fluid material (e.g. oil with thickener), or semisolid material (e.g. grease), or any mixture of such types of substance, which is used for the specific purpose of lubrication. |
