Protection of glazing in fire separations by sprinklers

This paper briefly describes the test facility and the test method which has been used to investigate the effectiveness of the special sprinkler systems. It provides the results of the test series to determine the maximum window width which can be protected by a single sprinkler, and the use of a multi-sprinkler system for the protection of very wide windows with and without millions. The paper also deals with the effectiveness of ceiling-mounted sprinklers. Evaluation of all cases is based on the two principal criteria for sprinkler protection of glazing materials exposed to fire; early activation and sufficient water spray.Nous d\ue9crivons bri\ue8vement dans ce document l?installation d?essai, ainsi que la m\ue9thode d?essai qui a \ue9t\ue9 employ\ue9e aux fins de l?investigation de l?efficacit\ue9 des syst\ue8mes de gicleurs sp\ue9ciaux. On y fournit les r\ue9sultats de la s\ue9rie d?essais visant \ue0 d\ue9terminer la largeur maximale de fen\ueatre qui peut \ueatre prot\ue9g\ue9e par un seul gicleur, et l?utilisation d?un r\ue9seau de gicleurs multiples pour prot\ue9ger les fen\ueatres tr\ue8s larges dot\ue9es ou non de meneaux. Le document s?int\ue9resse \ue9galement \ue0 l?efficacit\ue9 des gicleurs mont\ue9s en plafond. L?\ue9valuation de tous les cas \ue9tudi\ue9s est fond\ue9e sur les deux (2) principaux crit\ue8res relatifs \ue0 la protection par les gicleurs des mat\ue9riaux verriers qui sont expos\ue9s au feu, soit la pr\ue9cocit\ue9 du d\ue9clenchement et la quantit\ue9 d?eau qui est gicl\ue9e.Peer reviewed: YesNRC publication: Ye
