Flooring Radiant Panel Tester – TBB 913 FIRE CLASSIFICATION OF FLOORING PRODUCTS – DETERMINATION OF THE BURNING BEHAVIOR USING A RADIANT HEAT SOURCE ith ance w Accord 9-1 and In 923 EN ISO 1-1 and 0 EN 135 STM E648 on A Based Measurement Results Flame propagation distance over time Smoke gas density as a function of time Critical heat radiation The flooring radiant panel testing method is used in the United States of America (ASTM E648, ASTM E970, NFPA 253) and in Europe (ISO/EN 9239). The European Union has made this type of fire test one of the requirements for the approval of floor...

Temperature of the Test Chamber and Flame Area The floor covering to be tested is placed in a horizontal position under a gas-heated radiator that is inclined at 30° to the horizontal. In this position, the sample is exposed to a defined heat flow. The inclined radiant panel generates a defined heat radiation profile on the specimen ranging from a nominal maximum of 10.9 kW/m² to a minimum of 1.1 kW/m². The thermal load of the flooring in a corridor in the event of a fire is simulated. In accordance with EN 60584-1, temperature measurement occurs at the upper end plate by using a type K...

Trendsetting Technology Conform to Standard Pilot Burner The small stainless steel burner inflames the specimen. The flames emerge from a total of 35 holes and ignite the specimen zero line in the ignition position during the test. After ignition of the specimen’s hot end (3 mm above the edge of the sample holder), each flame front that forms is identified and documented as a function of time and length. The critical heat flux density in [kW/m²] is the heat flux acting on the part of the sample surface, from which the flames do not spread further and may subsequently extinguish and can be...

Burning Section During the test, the combustion distances are measured as a function of time, as the distance between the flame front and the sample zero line by a potentiometric position measuring system (uncertainty <1%). It is positioned via a hand wheel on the operating front of the TBB 913. The set lengths are transferred to the software and displayed. Temperature Measurement and Smoke Density The temperatures in the test chamber and exhaust channel are measured by two NiCrNi thermocouples. The white light measuring section consists of the measuring light source, measuring light...

Heat Flux Meter and Heat Flux Density Calibration by Heat Flux Meter In order to adhere to the corresponding norm, a heat flux profile must be recorded along the centerline of a calibration sample, more precisely a calcium silicate plate. To this end, a heat flux density detector of the SchmidtBoelter type is used to detect the heat flux density at nine defined positions (holes in the calibration specimen made of calcium silicate) at intervals of 100 mm. After a minimal heating of the chamber of one hour by means of the radiator until the temperature is stabilized, the SchmidtBoelter sensor...

Determination of the Heat Flux Density 12 Measured 10 Heat flux density /kW/m² The TBB 913 includes a watercooled heat flux density sensor of the Schmidt-Boelter type, which ISO standards officially call a heat flux meter. The well-proven heat flux measurement concept is generally referred to as the axial temperature gradient method. Its main purpose is the study of reaction to fire and fire resistance as applied, for example, in flammability tests and smoke chamber tests. For determination of the heat flux density within the sample area, the integrated heat flux meter measures the heat flux...

Testing the Smoke Density Light Measuring for the Determination of the Smoke Density The light measuring system consists of a light emitter and receiver which records the light signal attenuation as a measure of smoke density over time. At the start of a test, the initial value of the receiver is set at 100% via the touch panel. If flue gas is generated during the test, the intensity of the detected light signal decreases as a function of the optical density. The TBB software displays the measurement curve. Light transmitter and receiver are covered by additional windows, which are...

Euro Fire Classification For Floorings B2 Maximum security against fire E Basic security against fire FIRE CLASSIFICATION OF CONSTRUCTION PRODUCTS AND BUILDING ELEMENTS This European standard for the fire classification of construction products according to their reaction to fire tests defines the classes for the flammability of floor coverings which are now applicable throughout Europe. Further, the CE Mark for floor coverings specifies the testing or classification of flammability in accordance with EN 13501-1. Only achieved by non-flammable floor coverings which do not present any risk...
