In structures, such as land-based buildings, traffic tunnels, ships, aerospace vehicles, or submarines, compartmentalization is the fundamental basis and aim of passive fire protection. The idea is to subdivide a structure into "fire compartments", which may contain single or multiple rooms for the purpose of limiting the spread of fire, smoke and flue gases, in order to enable the three goals of fire protection: Fire-resistance rated wall assembly with fire door, cable tray penetration and intumescent [1] cable coating. ... Fire protection is the prevention and reduction of the hazards associated with fires. ...

The construction of such compartments and all its components is a matter of systems within systems, which use bounding to achieve Fire-resistance_ratings, all interdependent, forming part of an overall fire safety plan. All components forming part of such a compartments are subject to stringent bounding, in countries, where product certification is mandatory. For the Macintosh operating system, which was called System up to version 7. ... To meet Wikipedias quality standards, this article or section may require cleanup. ... International time/temperature curves used to run commercial furnaces for testing the Fire-resistance rating of passive fire protection systems, such as firestops, fire doors, wall and floor assemblies, etc. ... Product certification or product qualification is the cornerstone of all bounding and the process of certifying that a certain product has passed performance and/or quality assurance tests or qualification requirements stipulated in regulations such as a building code and nationally accredited test standards, or that it complies with a...
