Product Description:
The instrument is suitable for determining the effect of heat transfer through materials or material components when protective equipment is exposed to radiant heat. The instrument consists of an Inox metal chassis, an armored cage for protection and heating source, 6 silicon carbide heating rods (1.100°C)-with automatic electronic control power compensation, etc. Due to the aging of the rod and changes in line voltage-installed on a mobile support with automatic positioning, the central unit is automatically calibrated from 5 to 80 kW/m2 and fully automatic measurement process (the temperature can be increased by 12, 24 and 30° in several times) C), the sample holder is used to test A and B using the calorimeter, the LCD display is used to adjust and display the results, and the built-in printer.
Standards:
EN ISO 6942: Protective clothing - Protection against heat and fire- method of test: evaluation of materials and material asssemblies when exposed to source of radiant heat
Test principle:
A specimen is exposed to a specific level of radiant heat for a certain period of time. After exposure, check the sample (single layer or multiple layers) for visual changes. Sample B is exposed to a specific level of radiant heat, and the time required for the temperature to rise by 12°C and 24°C in the calorimeter is recorded, which can be expressed as the radiant heat transfer index.
