On the calibration of laser-cone calorimeters
Journal of Physics E: Scientific Instruments, 1968A method is described which allows the experimental determination of the heat capacity of laser-cone calorimeters. The method includes the usual calibration with a current pulse applied to the cone's heating coil, and a second calibration with d.c. current.

Combining cone calorimeter and PCFC to determine the mode of action of flame‐retardant additives
Polymers for Advanced Technologies, 2011 International audienceThe flammability of various flame retarded formulations containing different hydrated mineral fillers and/or phosphorous compounds and/or carbon nanotubes has been investigated using both cone calorimeter and PCFC.

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.

A cone calorimeter for controlled‐atmosphere studies
Fire and Materials, 1992AbstractMany fires occur in ambient atmospheric conditions. To investigate certain types of fires, however, it is necessary to consider combustion where the oxidizer is not 21% oxygen/79% nitrogen. The Cone Calorimeter (ASTM E 1354, ISO DIS 5660) has recently become the tool of choice for studying the fire properties of products and materials.

Testing of Mattress Composites in the Cone Calorimeter
Fire and Materials, 1997An 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

Precision of the Cone Calorimeter and ICAL Test Methods
Journal of Testing and Evaluation, 2011Repeatability and reproducibility are typically determined for standard fire test methods on the basis of an interlaboratory test program (round-robin) to define their precision. Significant differences in precision were found in the past between the repeatability and reproducibility of small-scale and intermediate- and large-scale fire test methods ...

Convection heat transfer in the cone calorimeter
Fire Safety Journal, 2009Abstract 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.

Development of a controlled-atmosphere cone calorimeter
Fire and Materials, 2000A 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.
