DX8348 Cone Calorimeter Heat Release Rate Test Apparatus 100kW/m² Radiant Cone for Building Materials ISO 5660

DX8348 Cone Calorimeter — Heat Release Rate Test Apparatus for Building Materials

The DX8348 Cone Calorimeter is a bench-scale oxygen consumption calorimeter used to measure the heat release rate, mass loss rate and smoke production of building materials, plastics, cables and textiles under controlled radiant heat flux. Heat release is calculated from the oxygen concentration of the combustion product gas stream — the single most important parameter for predicting fire hazard and for flame-retardant research and development.

Applicable Standards

• ISO 5660-1:2002 — Reaction-to-fire tests, heat release rate (cone calorimeter method)
• GB/T 16172-2007 — Test method for heat release rate of building materials
• Test principle also referenced by ASTM E1354 oxygen consumption calorimetry

Key Selling Points

• Accurate oxygen consumption measurement —  O₂ analyzer with 0-25% range and imported mass flow controller for stable, repeatable heat release rate data.
• Stable radiant heat flux — 5 kW truncated-cone heater delivering 100 kW/m² with three thermocouples and closed-loop temperature control.
• Automated exhaust flow control — frequency-converter driven fan with integrated orifice-plate flowmeter, automatically adjusted between 0.012 and 0.035 m³/s.
• Reliable sample weighing — 0.1 g accuracy and 0.01 g resolution load cell for precise mass loss rate curves.
• Complete gas conditioning train — imported PTFE smoke filter, PTFE moisture trap with peristaltic drain pump and Tecumseh compressor condenser with 0.1 °C dew point stability.
• Turnkey data system — ZWH4500 acquisition and control card with Windows database software, automatic data saving, editable report templates and batch processing tools.
• Serviceable in the field — manual and automatic control modes with universal casters for easy relocation in the laboratory.
