Fire protection equipment - Carbon dioxide extinguishing systems for use on premises - Design and installation (ISO 6183:2022, modified)

This document specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of fixed carbon dioxide firefighting systems in buildings, plants or other structures. It is not applicable to extinguishing systems on ships, in aircraft, on vehicles or on mobile fire appliances, or to below ground systems in the mining industry; nor does it apply to carbon dioxide pre-inerting systems.
Design of systems where unclosable opening(s) of the protected volume exceed a specified area and where the opening(s) can be subject to the effect of wind is not specified, although general guidance on the procedure to be followed in such cases is given (see 7.4.3.2).

Brandschutzeinrichtungen - Kohlenstoffdioxid-Löschanlagen für den Einsatz in Gebäuden - Planung und Einbau (ISO 6183:2022, modifiziert)

Dieses Dokument legt Anforderungen fest und enthält Empfehlungen für die Auslegung, Installation, Prüfung, Instandhaltung und Sicherheit von ortsfesten Kohlenstoffdioxid-Brandbekämpfungsanlagen in Gebäuden, Produktionsanlagen oder anderen Bauwerken. Es ist nicht anwendbar für Löschanlagen auf Schiffen, in Flugzeugen, auf Fahrzeugen oder auf mobilen Feuerlöschgeräten oder für unterirdische Anlagen im Bergbau; ebenfalls ist es nicht anwendbar für Kohlenstoffdioxid-Vorinertisierungsanlagen.
Die Auslegung von Anlagen, mit (einer) nicht verschließbaren Öffnung(en) des geschützten Bereichs, deren Fläche einen festgelegten Wert überschreitet und welche der Auswirkung von Wind ausgesetzt sein kann/können, ist nicht festgelegt, obwohl allgemeine Hinweise auf das in solchen Fällen zu befolgende Verfahren gegeben werden (siehe 7.4.3.2).

Équipement de protection contre l'incendie - Installations d'extinction par dioxyde de carbone utilisées dans les bâtiments - Conception et installation (ISO 6183:2022, modifiée)

Le présent document spécifie les exigences et donne des recommandations pour la conception, l’installation, les essais, la maintenance et la sécurité des installations fixes de lutte contre l’incendie par dioxyde de carbone dans les bâtiments, les usines ou autres structures. Il ne s’applique pas aux installations d’extinction des navires, des aéronefs, des véhicules ou des appareils mobiles d’incendie, ni aux systèmes souterrains de l’industrie minière. Il ne s’applique pas non plus aux systèmes de pré inertage par dioxyde de carbone.
La conception de systèmes dans lesquels la ou les ouvertures non fermées du volume protégé dépassent une surface spécifiée et la ou les ouvertures peuvent être soumises à l’effet du vent n’est pas spécifiée, bien que des recommandations générales sur le mode opératoire à suivre dans de tels cas soient fournies (voir 7.4.3.2).
