Procedure A exposes a specimen in a free-standing frame to a defined heat radiation for a defined time period. The intensity of the heat radiation is controlled by the distance between specimen and heat radiation source. After the testing the specimen and its different layers are examined for visual changes.
In procedure B the specimen is fixed onto a calorimeter and exposed to a defined heat radiation. The time needed for a temperature rise in the calorimeter of 12°C and 24°C respectively is measured.
On the basis of this data the heat throughput rate is calculated from the difference between passed and incident heat flow density. The software includes the calculations and evaluation of the standard. The power supply is provided by a three-wire plug 3 ~ 400 VAC (50/60 Hz) (5x32 A 6h CEE). The cooling device is equipped with an industrial cooler with closed cooling circuit, temperature control and alarm function for cooling the shield. It has a cooling capacity of 1700 W.
