SBI Building Products Single Burning Item Flammability Testing
Equipment / Device EN13823
It is suitable for the testing the fire resistance of building
materials / products in single burning item (SBI).
1.The core part of the machine are imported components: such as
carbon dioxide, oxygen analysis equipment.
2.Operating interface style and performance equivalent to the
United Kingdom FTT, some performance is better.
3.Easy maintenance, fast, late parts replacement than FTT minimum
less than 50% to 70%, there will be no maintenance problems.
4.With imported integrated control cabinet.
1.Composition: this test equipment includes combustion laboratory,
control room, 2 small carts, exhaust pipe, fixed frame, flue gas
collection system, integrated measurement system device, data
collection and analysis device, gas supply control device.
2.Combustion chamber: long (3.0 ± 0.2) m × width (3.0 ± 0.2) m ×
high (2.4 ± 0.1) m.
3.With stainless steel plate and calcium silicate board A1 plate
composed of standard combustion chamber, test furnace should be
installed at local;
4.At the top of the room there is a collecting hood and a smoke
pipe connecting the sampling piping. The combustion heat release
and combustion products of the sample are discharged from the
exhaust pipe during the test.
5.Combustion chamber on a wall set up an opening, easy to enter the
small cart, under the trolley air naturally out of space; vertical
test plate on both sides of the front surface of the two sides were
opened on the observation window.
6.Ignition source, placed in the trolley on the vertical corner of
the 31KW propane right angle sandbox burner (side length 250MM high
7.The position of the cart is to place the opening of the cart on
the back of the cart just to close the openings in the combustion
chamber wall. To distribute the airflow evenly along the combustion
chamber floor, a perforated plate (perforated) is arranged at the
air inlet at the bottom of the trolley Diameter 8mm, open area
accounted for 60% of the total area).
8.With adjustable governance fixture, loading and unloading samples
is very convenient.
9.Sandbox burner: one on the floor of the trolley (main burner),
the other fixed on the frame column, propane gas through the
sandbox burner and produce 30.7 ± 2.0kW heat output.

Record data acquisition system can collect oxygen concentration,
carbon monoxide concentration, temperature, smoke density, heat
release rate, mass loss rate, etc., can be stored.
A sample consisting of two vertically angled vertical wings is
exposed to the flame produced by the main burner at the bottom of
the right angle, the flame is produced by the combustion of propane
gas, the propane gas passes through the sandbox burner and produces
(30.7 ± 2.0) kW of heat output.
The combustion performance of the sample was evaluated by the
entire test procedure of 20 min. Performance parameters include:
heat release, smoke production, flame propagation and burning
dripping and particulate matter.
Prior to igniting the main burner, the heat output and smoke
generation of the burner itself should be measured for a short time
using the auxiliary burner remote from the sample.
Some parameters can be measured automatically, while others can be
obtained by visual inspection. The smoke pipe is equipped with a
sensor for measuring the temperature, light attenuation, the mole
fractions of O2 and CO2, and the airflow in the pipeline. These
values are automatically recorded and used to calculate the
volumetric flow rate, heat release rate (HRR) and smoke rate (SPR).
The transverse propagation and burning of the flame and the
particulate matter can be measured using a visual method.
