IEC TR 62222:2012

Fire performance of communication cables installed in buildings

IEC/TR 62222:2012 provides recommendations for the requirements and test methods to be specified for the fire performance of communication cables when installed in buildings. The recommendations relate to typical applications and installation practices for copper and optical cables in buildings. This TechnicalReport includes an assessment of the fire hazards presented by such installations, and describes fire scenarios that have been established and the appropriate cable fire performances to mitigate these hazards. ISO/IEC 14763-2 recommends installation methods which,together with this Technical Report, provide guidelines for improving safety during fire. The recommendations also take into account legislation and regulation applicable to the fire performance of cables, an assessment of known test methods and their ability to measure the recommended fire performance. Power cables are usually segregated from communication cables for electrical safety and installed differently so they have not been addressed in this Technical Report.

Tenue au feu des câbles de communication installés dans les bâtiments

La CEI/TR 62222:2012 fournit des recommandations pour les exigences et les méthodes d'essai à spécifier pour la tenue au feu des câbles de communication quand ils sont installés dans des bâtiments. Les recommandations traitent des applications classiques et des pratiques d'installation dans les bâtiments pour des câbles en cuivre et des câbles à fibres optiques. Ce Rapport technique contient une évaluation des dangers d'incendie dans ce type d'installations, et décrit des scénarios d'incendie qui ont été établis et les tenues au feu des câbles appropriées pour limiter ces risques. L'ISO/CEI 14763-2 recommande des méthodes d'installation qui, ensemble avec ce Rapport technique, fournissent des lignes directrices améliorant la sécurité en présence du feu. Les recommandations tiennent également compte de la législation et de la réglementation applicables à la tenue au feu des câbles, d'une évaluation des méthodes d'essai connues et de leur capacité à mesurer la tenue au feu recommandée. Les câbles électriques sont habituellement séparés des câbles de communication pour la sécurité électrique et installés différemment, ils ne sont donc pas abordés par le présent Rapport technique.
