Notes:
Ignitability, one of the new fire test methods for building materials developing within the International Standards Organization is compared with the national fire test methods in Austria, Britain, France, Germany and Scandinavia. Different commercial wood-based panels have been tested, including fire retardant treated panels. The International Standards Organization ignitability test measures the time to ignition at radiation intensities from 1 to 5 Wm -2; it seems to be able to distinguish between different materials in an intelligible way. An evaluation of the results of this ignitability test is discussed. One possibility which is proposed here is to calculate the mean time to ignition at different fixed radiation intensities; such a mean value simplifies the evaluation and takes into account all the test data. Agreement with the national fire test methods is rather low, since they partly measure other fire parameters; agreement with the Austrian Schlyter method, which also evaluated ignitability, is somewhat better and agreement between the national fire test methods is relatively good for wood-based panels. This is consistent with earlier experience, which has shown that mainly new types of materials behave differently according to different national test methods.
