Methane calibration burner and C-factor determination with cone calorimeter - validation of the standardized calibration protocol

摘要

The cone calorimeter is one of the major fire tests. In its reference standard ISO 5660-1, the apparatus (and especially a characteristic of its orifice plate mass flow meter, called C-Factor) is calibrated using a methane burner set at 5kW. However, measurements performed in end-use are in the range 1-10kW. In addition, standard proposes to check linearity at 1 and 3kW, which means in the lowest part of the range. This communication establishes the validation of the linearity on the whole range and determines the optimal condition for C-factor determination. It justifies the technical choices of the standard.
