single burning item machine for building materials

1.Scope of application:

1.1 test methods applicable to the determining the reaction to fire behaviour of building products  (excluding floorings and products referred to in EC Decision 2000/147/EC) when exposed to the thermal attack by a Single Burning Item (SBI).

2.Compliant standards:

2.1 Meet the requirements of GB/T 20284-2006 Standard "Single burning item test for building materials and products".

2.2 Complies with BS EN13823:2002 "Reaction to fire tests for building products—Building products excluding floorings exposed to the thermal attack by a single burning item"

2.3 Comply with BS EN13238:2010 "Reaction to fire tests for building products—Conditioning procedures and general rules for selection of substrates"

3. the main parameters:

3.1 The complete set of equipment includes combustion chamber, test equipment, J-type exhaust pipe, flue gas collection system, integrated measurement system device, data collection and analysis device, and gas supply control device.

3.2 One burning test chamber:

3.2.1 burning chamber: length (3.0±0.2)m×width (3.0±0.2)m×height (2.4±0.1)m. built with brick walls;

3.2.2 At the top of the room, there is a gas collecting hood and a smoke exhaust pipe connected to the sampling pipe. During the test, the heat released by the burning of the sample and the burning products should be discharged from the smoke exhaust pipe.

3.2.3 There is an opening on one wall of the burning chamber, which is convenient for the trolley to enter. There is a space for air to enter and exit naturally under the trolley. There are observation windows on the two walls facing each of the long and short wings of the vertical sample plate.

3.2.4 There is a door that can be closed on one side of the burning chamber, which is convenient for cleaning the test residues in the room after the test.
