| Summary | On September 15, 2009, the notification No.1729 of the Ministry of Construction in 1969 was revised to adopt smoke exhaust equipment equipped with an air supply fan to pressurize the vestibule. But specification of the smoke duct has not been specified yet, it is requested to specify test method to evaluate the performance and specification. Also it is needed to develop barometric damper to prevent excess pressure difference by the work of an air supply or exhaust fan. In this research, performance of insulation, smoke and flame blocking, of smoke duct and barometric damper was tested using fire furnace. Based on them, specification of smoke duct and guideline were developed for maintaining the performance of barometric damper as opening protective assembly. |
