• What is the oxygen index test?

  What is the oxygen index test?Oxygen concentration values are known as the Oxygen Index (OI) or, historically, the Limiting Oxygen Index (LOI). The oxygen concentration is measured using a paramagnetic oxygen analyzer and is controlled by varying the relative flow of oxygen and nitrogen through a ve

• Determination of Combustion Properties in Cone Calorimeter

  Determination of combustion properties in cone calorimeter A plurality of performance parameters of the combustion debris can be obtained using a cone calorimeter, such as heat release rate, mass loss rate, smoke generation rate, effective heat of combustion, ignition time, and toxicity and corrosivity concerning combustion gases. These performance parameters are determined under stable, real, and controllable conditions, and can be repeated at different times and locations. Therefore, it can be used as a reference for literature reference data to provide literature data for more research materials.
