The device is used to determine the heat transmission of flame exposure to protective clothing against heat and flames. A classification of materials can be made by comparing the determined heat transfer indices, which serve as a reference for the relative heat transfer under the specified test conditions.
A specimen is placed in a specimen holder.
A calorimeter is placed directly on the inside of the specimen. The soecimen is then exposed to a heat flow of 80±2 kW/sqm generated by a propane gas burner. The time required to raise the temperature at the specimen by 24 °C is measured.
Type of specimen: | Protective clothing against heat and flames |
Test standards: | EN ISO 9151 |
Sensors: | Heat flux (Calorimeter, thermocouple Type-T), gas flow, time, thermocouple Type K (flame protection), position switch linear drive, ambient temperature, humidity |
| Special features: | The test is automated, with a laptop taking over the device control and recording of measurement data.
The sample holder is moved by means of an electric linear drive. Due to the high traversing speed, a closing element is not necessary. The burner is equipped with a pilot flame safety device and an electric ignition. The device is enclosed on 5 sides and equipped with a hinge switch on the door, which switches off the linear drive when the door is opened.

For cooling the calorimeter a cooling device with electric fan is available. |
Supplies: | 230 VAC / 150 VA Flue gas exhaust, compressed air Propane gas |
Dimensions (Test frame): | approx. 680 x 740 x 610 mm (W x h x d) |
Weight (Test frame): | approx. 50 kg |
