The key focus of the research is on the smoke leakage rate from suspended ceiling system, referencing CNS 15038 norm and its experimental principles to build a set of monitoring equipment for measuring air leakage rate and the provision of detailed assembly details for users’ reference. Through the real-size test chamber, the smoke insulation performance of the ceiling is studied. Targeting the different ceiling materials, ceiling panels dimensions, and construction methods, in keeping with the scientific principles of fluid mechanics, a total of 405 tests are carried out to come up with the means of appraising the leakage rate of ceiling panels of different sizes and materials. The study found that with the ceiling panel material quality being different, even if the ceiling size is the same, different leakage rates could occur. When the material quality of the ceiling panels is the same and the ceiling size is different, it is not that the larger the size of the panel, the greater the leakage rate, but the smallest leakage rate is caused by the largest panel and this is a very special phenomenon. This study also presents a leakage rate assessment table for entire ceiling panels, which will provide future calculations of the smoke leakage rate of the non-flame room, which can be extrapolated to assess the time of smoke decline and conducive for evacuation design. The apparatus has been proven to have proper leakage rate detection capability for the ceiling panels. In the future, the design principle of the extended system can be applied to the inspection and testing of smoke insulation capability of other fire prevention products. In turn, it can be estimated when the smoke has fallen to facilitate escape design. View Full-Text
