What is Cone calorimeter: Initial experiences of calibration and use about?

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 tests, it was necessary to establish the effect of instrument variables on test data and of possible instrument~material interactions. Cast, thick, black polymethyl methacrylate (PMMA) sheet is an ideal calibration material. Attempts to obtain this type of material in usable quantities were unsuccessful and tests were carried out using various adhesives to construct a thermally thick specimen. Alternative systems based on thin black PMMA and transparent PMMA sheets were also evaluated. The cone calorimeter has shown itself to be an extremely useful instrument capable of determining basic fire parameters under preset heat flux conditions. Test repeatability can be extremely good depending on the material and test regime. Considerable care is required to interpret data since relatively few materials show pseudo-steady-state burning and data may d
