47、cimen. See Annex A.4 PrincipleA horizontally oriented test specimen is restrained from moving and subjected to an incident heat flux of (80 2) kW/m2from the flame of a gas burner placed beneath it. The heat passing through the specimen is measured by means of a small copper calorimeter on top of and

48、 in contact with the specimen. The time, in seconds, for the temperature in the calorimeter to rise (24 0,2) C is recorded. The mean result for three test specimens is calculated as the “heat transfer index (flame)”.5 Apparatus5.1 GeneralThe apparatus consists of: a Meker gas burner; a copper disc c
