A Mathematical Model of Ignition in the Cone Calorimeter

Combustion Science and Technology, 1995
We establish a mathematical model for the ignition of a thermally thin polymeric material in the Cone Calorimeter (autoignition mode). The model contains equations for solid phase and gas phase variables, and the two phases are coupled nonlinearly. Of particular importance are the couplings through convective and radiative heat transfer.

Uses of the Cone Calorimeter

Cellular Polymers, 1993
This paper describes a series of small experimental programmes to investigate the use of the cone calorimeter with different materials. The difficulties of testing materials which swell or shrink significantly when heated and the nature of the cone calorimeter fire model were also investigated.

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

The Cone Calorimeter

2016
Chapter 27 describes the history and development of techniques for measuring heat release rate (HRR). This chapter outlines features and details of today’s preferred instrument for measuring bench-scale HRR—the cone calorimeter.

Development of a controlled-atmosphere cone calorimeter

Fire and Materials, 2000
A controlled-atmosphere cone calorimeter has been developed that overcomes many of the shortcomings of previously developed units. The new apparatus is a fully sealed 'blow-through' system, which provides a full-size chamber in which the combustion process can occur.

Comparison of Black and Transparent PMMA in the Cone Calorimeter

2023
The cone calorimeter is one of the standard devices used to assess the flammability of polymers. Several publications have been made studying different types of polymers and different set-ups in this apparatus. Polymers come in different forms and colors. It is unknown, however, whether the color of a polymer influences its burning behavior in the cone

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.

Application of Cone Calorimeter on the Flammability Testing of Textiles

Advanced Materials Research, 2011
In the present work, cone calorimetric technique has been widely used to study the flammability of polymer. But there are few reports about the cone calorimetric technique exploited for textile. The flammability of cotton fabrics selected in this study was tested by cone calorimeter.

Flammability parameters of wood tested on a cone calorimeter

Polymer Degradation and Stability, 2001
Abstract The effect of different loads of magnesium hydroxide as flame retardant on the flammability parameters of particleboard was studied. The effect of different flame retardant combinations was also compared. The flammability parameters were measured on a cone calorimeter at the uniform external irradiance of 50 kW m −2 for all modifications ...

Spectral responses of laser cone calorimeters

Journal of Physics E: Scientific Instruments, 1972
For a polished nickel plated cone of angle 15 degrees , calculation suggests an optical absorption (response) which, normalized to unity at wavelength 0.4 mu m, falls to 0.99 at 0.7 mu m, 0.95 at 1.5 mu m, 0.90 at 1.9 mu m, and 0.85 at 2.3 mu m. Experimental comparison of the readings of such a cone calorimeter with those of a black detector, using ...
