Latest Cone Calorimeter Fire Testing Equipment for Heat Release Rate Analysis
The cone calorimeter is the most important bench scale instrument in the field of fire testing. Heat release is the key measurement required to assess the fire development of materials and products, and no other small scale test provides such a complete picture of real fire behaviour. DAXIAN's latest cone calorimeter fire testing equipment brings laboratory grade heat release rate analysis to manufacturers of building materials, furniture, cables, plastics and composites.
How the Cone Calorimeter Works
The instrument is named after its truncated conical heater, which irradiates the specimen at a controlled heat flux. Heat release is measured using oxygen depletion calorimetry, based on the principle that the heat released by burning materials is directly proportional to the quantity of oxygen consumed during combustion. This method, originally developed at NIST, overcomes the limitations of older enclosure based heat release tests and delivers accurate, reproducible results.
Key Measurements
- Heat release rate (HRR): the primary indicator of fire growth and hazard.
- Time to ignition (TTI): how quickly a material ignites under a given heat flux.
- Peak and total heat release: for ranking material fire performance.
- Mass loss rate: continuous weighing station tracks specimen mass during the test.
- Smoke production rate: optical smoke density measurement for evacuation safety.
- Effective heat of combustion and CO/CO2 yields: via gas analysis system.
Standards Compliance
The cone calorimeter supports the leading international fire testing standards, ensuring results are accepted worldwide:
| Standard | Scope |
|---|
| ISO 5660-1 | Reaction to fire tests - heat release, smoke production and mass loss rate |
| ASTM E1354 | Heat and visible smoke release rates using an oxygen consumption calorimeter |
| BS 476-15 | Method for measuring the rate of heat release of products |
| ASTM D6113 | Cone calorimetry for electrical and optical fiber cable materials |
| EN 13823 (SBI correlation) | Prediction of single burning item and room corner fire performance |
System Structure
Each system integrates an ignition source, conical collector, exhaust pipes and fan, weighing station, gas sampling and analysis system, gas control system and smoke density measurement system. Built-in temperature sensors, gas flow meters, gas sampling probes and a multi-stage filter sampling line guarantee long service life and stable, accurate readings.
Applications
The cone calorimeter is widely used for building materials, wall and ceiling linings, furniture and upholstery, cables, plastics, composites and products under development, allowing manufacturers to compare formulations and eliminate materials that do not meet the required fire characteristics before full scale testing.
