Abstract

Abstract: For the sake of determining RDD for extinguishing the fires in typical places, an RDD test system was established. With dismountable structure and integrated design, the system was made up of a water distributing system,a frame and a control system. It was applied to determining RDD of the minimum unit of fire-test model of medium risk II industrial building. The result shows that under the specified experimental condition, the RDD value of the test model is about 10.0 mm/min.

Key words: required delivered density (RDD), combustible products, fire test model, sprinkler systems, full scale fire
