An apparatus has been constructed and data evaluation techniques developed for quantifying the ease of ignition of fabrics exposed to a small flame. The method takes careful account of fabric moisture content, which can have a substantial influence on this form of ignitability. A proposed specific ignition resistance coefficient, obtained from yes-no trials at preset exposure times, is inde pendent of fabric weight and ambient humidity, so that ignitability can be compared on a common basis.
