Abstract
A calorimeter for measuring flammability parameters of materials using only milligram sample quantities. The thermochemical and thermophysical processes associated with the flaming combustion of solids are reproduced in the device through rapid anaerobic pyrolysis in a thermogravimetric analyzer. Volatile anaerobic thermal decomposition products are swept from the pyrolysis chamber by an inert gas and combined with excess oxygen in a combustion chamber maintained at several hundred degrees Centigrade to simulate the combustion reactions which occur in a well ventilated diffusion flame. Mass loss is measured continuously during the process and heat release rate is calculated from the oxygen consumed from the gas stream.

Flammability behaviour of wood and a review of the methods for its reduction

TL;DR: In this paper, potential approaches for fire retarding timber are reviewed, identifying two main approaches: char formation and isolating layers, and other potential approaches are recognised, including the use of inorganic minerals, such as sericrite, and metal foils in combination with intumescent products.

Estimation of rate of heat release by means of oxygen consumption measurements

TL;DR: In this paper, the authors proposed a method based on the generalization that the heats of combustion per unit of oxygen consumed are approximately the same for most fuels commonly encountered in fires, which can then be converted to a measure of heat release.

Heat release rate: The single most important variable in fire hazard☆

TL;DR: In this paper, the authors explain why heat release rate is, in fact, the single most important variable in characterizing the "flammability" of products and their consequent fire hazard.
