Single Burning Items BS EN 13823
Introduction
SBI was measured supplies (excluding floorings) performance at a single burning heat invasion conditions.
Samples were placed inside the sliding flame (methane combustion sandbox boxes), under the exhaust pipe.
Sample combustion reaction condition to accept dual monitor machine and visually. Heat and smoke
release rate assessment instruments detect objects by observing performance.
The sample is placed on a mobile cart located in the exhaust system under the combustion reaction of the
sample can be automatically displayed and visible. By calculating the heat release rate (HRR), smoke
release rate (SRR) to evaluate the combustion characteristics of the machinery, and other physical
properties evaluated by visual observation. SBI measurement range, the fire growth rate index (FIGRA) is
the most representative measure factors; in addition, there are factors measuring oxygen consumption
representative, CO/CO2 generation amount, smoke growth rate index (SMOGRA) and so on. Maximum
heat release rate can reach 1MW.
