The Fourier Transform infrared spectrometer method is developed by VTT Fire Technology in Finland, and is described by NORDTEST as NT FIRE 047. The method takes gas samples from the ventilation duct of a cone calorimeter, and is used to perform dynamic quantitative or qualitative measurements. This is an important step in the direction of continuous measurements of gas components in fire smoke. A lot of effort, knowledge and funds are required for a proper calibration and use of this equipment. The experience with application and interpretation of the test method is reviewed in regard to mounting, calibration and use of the equipment. The work concludes that the NORDTEST NT FIRE 047 test method needs to be revised and completed in the sections on apparatus, calibration routines, analysis procedure and expression of results. The missing information and details can lead to differences in application of the method. Until a revised document appears, frequent communication between laboratories can eliminate these differences.
