Burning behavior of curtains - measuring the flame spreading behavior of vertically fixed specimen exposed to large ignition sources. The device tests textiles and textile products, assessing the burning behavior and flame spreading behavior of vertically fixed specimen. The device consists of the burning box, a pneumatically controlled burner which is adjustable vertically and has more than 3 angle positions, the burner's moving mechanism, an irradiator, a calorimeter and the mechanism for fixing the specimen. The temperature control of the irradiator, the moving of the burner and the shield and the data collection is software controlled. The testing process can be defined in a simplified manner as follows: A heat flow with defined thermal rating is directed through a fixed plate in the lower part of the backside of the vertically fixed specimen. After 30 s a small flame (see DIN EN ISO 6941) is directed to a small piece of cotton tissue for 10 s where the tissue is fastened around the specimen's edge. The possible flame spread is measured through the breaking of the marking threads.

The device is used to determine the flammability of building products (materials, composites and components). The specimens are exposed to heat radiation of 10 to 70 kW/m³ generated by an electric cone radiator. During this process, the specimen is pressed against a pressure plate with a defined force. In addition, the gases detaching from the specimen are ignited by means of a periodically applied pilot flame. The time that elapses until the specimen ignites is measured..

Reaction-to-fire tests - Heat release, smoke production and mass loss rate The test device is used to access the reaction of building materials to the effect of heat. Heat release, smoke production and mass loss rate are measured. The main function of the Cone Calorimeter is based on the knowledge that the net heat of combustion is in fact proportional to the amount of oxygen required for combustion. The ratio is approximately that 13.1 x 1000 kJ of heat is released per kilogram of oxygen consumed during combustion. The samples are irradiated under laboratory conditions, ignited by sparks and thereby burned. They are exposed to thermal radiation at fixed intervals between 10 kW/sqm - 75 kW/sqm and the changes in oxygen and gas concentration are measured. The principle is called the "oxygen consumption principle" and originates from calorimetry. Furthermore, the flow rate in the exhaust pipe and the loss of mass of the sample are measured. Smoke obscuration is measured as the intensity of the laser light that is transmitted through the smoke in the exhaust pipe. The measurement is used to calculate the extinction coefficient according to Bourger's law. The test results are used to determine smoke production and smoke production rate.

Description of fire behavior in case of exposure to a radiant heater. The results of this test process are the basis for evaluating one aspect of the fire behavior of floor coverings. The heat radiation sent to the sample by the heater simulates the likely degree of stress to the floor in a corridor of which the top side is affected by flames and/or heat gases during the early phase of the development of a fire in a room or section against the air flow. The sample is placed in a horizontal position under the gas-heated radiant heater that is inclined by 30° against the horizontal line. The sample is exposed to a certain heat stream. A pilot flame is brought into contact with the hot end of the sample. After the ignition, every forming flame front is determined and the horizontal spread of the flame front along the sample length is recorded as the time needed by the flame front so that it spreads over the determined distance. The smoke development in the flue is recorded by registering the weakening of light during the test. The software serves for the control and measurement data recording. It provides the functions of calibrations, valve control, preheating and CHF calculation.

In the lower corner formed by the specimen wings, a sand bed burner simulates a burning item, e.g. a burning waste container. A second identical burner, which is ignited shortly before the main burner, serves to determine the heat development and heat release of the burner on its own. In addition to the development of the fire, it is determined whether parts of the specimen drip off or fall off.

Lateral spread of flame on vertically arranged construction products The results of this testing procedure are used as a basis for evaluating the burning behavior of a lateral flame which spreads along a specimen. The heat radiation which a radiant heater applies to a specimen simulates the probable degree of stress that acts upon a specimen in a fire scenario. The sample is placed in a horizontal position under the gas-heated radiant heater that is inclined by 15 +/- 3° against the horizontal line. The sample is exposed to a certain heat stream. A pilot flame is brought into contact with the hot end of the sample. After ignition any flame front that forms is registered and its horizontal spread along the length of the specimen is recorded as the time the flame front needs for spreading over defined distances. Controlling the device and measurement data recording as well as data processing is done via the software. It provides the calibration, valve control, preheating and CHF calculation.
