Monomer combustion test device for building materials
The Monomer Combustion Test Device for Building Materials, also known as a Single Burning Item (SBI) Test Apparatus, is designed to evaluate the reaction-to-fire performance of building materials and products when exposed to a single burning item under controlled laboratory conditions. The system is designed with reference to GB/T 20284 and EN 13823 test requirements.
Application
(1) Building boards and panels
(2) Wall and ceiling construction products
(3) Insulation materials
(4) Polymer-based building materials
(5) Composite building products
(6) Construction materials requiring single burning item (SBI) testing
(7) Building material fire performance research and development
(8) Fire testing laboratories and quality inspection institutions
Standards
Comply with GB/T 20284 standard requirements "Building materials or products of the single combustion test"
EN13823 "Monomer Combustion Test Method (SBI)".

Features
1. Single combustion test equipment for building materials or products includes combustion test room, control room, trolley, smoke exhaust pipe, data collection and analysis device, gas supply control device,
2, the core parts of the whole machine are imported components: such as carbon dioxide, oxygen analysis instruments, etc.
3, the operation interface style and the performance of all parties is equivalent to the British FTT, some performance is better than it,
4. Convenient and fast maintenance, the replacement of spare parts in the later period is less than 50%——70% than FTT, and there will be no maintenance problems.
5. Adopt imported integrated control cabinet
Maintenance Information
(1) Inspect the propane burner and gas supply connections regularly for leakage, blockage, or damage.
(2) Check the oxygen and carbon dioxide analyzers according to the manufacturer's calibration recommendations.
(3) Inspect the exhaust duct and sampling area for obstructions or accumulated deposits.
(4) Verify the operation of the pressure regulator and glass rotor flowmeter before testing.
(5) Check the data acquisition board, sensors, and computer communication system for stable operation.
(6) Keep the combustion chamber and trolley clean and free from accumulated test residues.
(7) Inspect the integrated control cabinet and electrical connections regularly.
(8) Maintain the gas supply, ventilation, and fire safety systems according to the laboratory's safety procedures.
