Convection heat transfer in the cone calorimeter

Fire Safety Journal, 2009
Abstract Estimates of the convection heat transfer coefficient (HTC) in the cone calorimeter are obtained from a near-steady-state analysis of the temperature histories of horizontal coated steel plates. Corrections are applied to the derived HTC values to account for changes of the surface emissivity as a function of temperature.

Calibration of flow rate in cone calorimeter tests

Fire and Materials, 2013
ABSTRACTThe cone calorimeter is one of the major fire tests. The measurement method is based on the evaluation of mass flow and oxygen concentration of fire effluents to calculate heat release rate. Different studies highlighted that the governing parameter for uncertainty at important values of heat release rate was the characteristic constant of an ...

Testing of Mattress Composites in the Cone Calorimeter

Fire and Materials, 1997
An investigation of cone calorimeter test procedures was performed using two types of mattress composites with various specimen preparations and equipment configurations. The objective was to discover suitable procedures for testing mattress composites. Concurrent with this work a much larger and more sophisticated project known as CBUF was underway in

Analysis of Polymers Using the Cone Calorimeter

1991
The use of polymeric materials in building or construction applications is steadily increasing. Therefore, the potential for these materials to be exposed to fire is also increased. The pyrolysis characteristics of these materials and the understanding of their pyrolysis characteristics is thus a necessity.

Cone calorimeter: Initial experiences of calibration and use

Fire Safety Journal, 1994
Abstract The primary objectives after taking delivery of a cone calorimeter were to develop operator skills and to establish the reliability, accuracy and repeatability of the instrument. Since the instrument would be used with a wide range of plastics and rubber materials, for research and development of materials and additives, and also for routine

PVC Cable Fire Toxicity Using the Cone Calorimeter

2016
Electrical cables with PVC sheaths were investigated for their ignition characteristics, heat release and toxic yields using the cone calorimeter. 40 KW/m2 was required to get a significant heat release for PVC. A heated Temet Gasmet FTIR was used for the toxic gas analysis.

An accurate carbon cone calorimeter for pulsed lasers

Journal of Scientific Instruments, 1967
The requirements for a laser calorimeter are discussed with reference to a particular thick walled carbon cone equipped with eight thermocouples and a resistance wire to discharge a known energy for calibration purposes. The main sources of error are: (i) incomplete absorption of the laser beam; (ii) the cooling error due to the finite time for ...

Investigation of polymeric materials using the cone calorimeter

Polymer Engineering & Science, 1993
AbstractThe use of polymeric materials in building or construction applications is steadily increasing. Therefore, the potential for these materials to be exposed to fire is also increased. The understanding of the pyrolysis characteristics of these materials is thus a necessity. There are many standard tests used to evaluate materials.

Cone Calorimeter Studies of Furniture Component System

1994
The thermal performance for a wide range of upholstery fabrics made in various weights and fiber types has been studied. A cone calorimeter was utilized for this work using simulated furniture mockups of cover fabric, with and without Kevlar Z-11 fire blocker fabric and foam.
