El microcalor\u00edmetro FTT<\/strong><\/span><\/span> FAA (ASTM D7309) ha sido desarrollado en colaboraci\u00f3n con la Federal Aviation Administration (FAA). Determina datos termoqu\u00edmicos fundamentales en segundos y predice las propiedades antiincendios de os materiales.<\/p>\n

La t\u00e9cnica permite determinar r\u00e1pidamente par\u00e1metros como la tasa de liberaci\u00f3n de calor espec\u00edfico (W\/g), el calor de combusti\u00f3n (J\/g) y la temperatura de ignici\u00f3n (\u00baC) a partir de muestras de tama\u00f1os muy peque\u00f1os (1-5mg). Es una t\u00e9cnica poco costosa y precisa, con una reproducibilidad t\u00edpica del \u00b1 5%.<\/p>\n

Se muestran los datos del microcalor\u00edmetro para correlacionarlos con los datos del ensayo antiincendios (cono calorim\u00e9trico, OSU), resultados de inflamabilidad (LOI, UL94) y ensayos de combusti\u00f3n (Bomba calorim\u00e9trica)<\/p>\n

The FAA FTT<\/strong> Micro Calorimeter uses the same oxygen consumption calorimetry technique used in FTT<\/strong>‘s bench and room scale calorimeters. The specimen is first heated at a constant rate of temperature rise (typically 1\u00b0C\/s) in a pyrolyser and the degradation products are purged from the pyrolyser by an inert gas (nitrogen). The gas stream is mixed with oxygen and enters a combustor at 900\u00b0C where the decomposition of products are completely oxidised. Oxygen concentrations and flow rates of the combustion gases are used to determine the oxygen consumption involved in the combustion process and the heat release rates are determined from these measurements.<\/p>\n
