BS EN 13823 Single Burning Item Test Apparatus (SBI) for Building Materials
The Single Burning Item (SBI) test apparatus is designed to evaluate the fire performance of building materials (excluding flooring materials) under controlled thermal attack conditions. This sophisticated equipment provides comprehensive analysis of material combustion behavior through automated testing and precise measurements.
Key Testing Capabilities
Determines performance of building materials under single combustion heat attack conditions
Automated visual observation of specimen combustion reactions
Mechanical properties evaluation through heat release rate (H.R.R) and smoke release rate (S.R.R) calculations
Physical properties assessment via visual observation
Fire Growth Rate Index (FIGRA) as the primary measurement factor
Additional measurement parameters: oxygen consumption, CO and CO₂ generation, smoke growth rate index (SMOGRA)
Maximum heat release capacity up to 1MW
Test Room Dimensions: 3000mm × 3000mm × 2400mm (L×W×H)
