Product Details
Products:
Single burning instrument (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 movable cart located under the exhaust
system, and 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 material, 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.
