Data Management
representation of a concept by a descriptive statement which serves to differentiate it from related concepts
Note 1 to entry: A definition may be expressed as natural language text (a textual definition) or as a definition model. A textual definition should comply with the applicable guideline(s) in this standard. A definition expresses what is by definition the case for all things of the defined kind and if such an expressed constraint is not the case for a thing, then that thing is not a thing of the defined kind.
A definition model is a subtype of a knowledge model and consists of a number of expressions of facts about the defined concept. Those expressions should comply with the guidelines in this standard.[1]

BS 8519:2020, with emphasis on Clause 7 (Cable Routing) and Clause 11 (Cable Selection)
The goal: clarify requirements for the diverse cable routing and maintain circuit integrity under fire conditions for systems that support life safety and fire-fighting applications, such as sprinkler pumps, fire-fighting lifts, and smoke control systems.
