A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum.lthough the flame test only gives qualitative information, not quantitative data about the proportion of elements in the sample, quantitative data can be obtained by the related techniques of flame photometry or flame emission spectroscopy. Flame Atomic absorption spectroscopy Instruments, made by e.g.
the measurement obtained to the flame spread along a select red oak and fiber cement board. the number obtained from the test, the greater the flame spread potential of that material. Tunnel Test was used to evaluate and rate a carpets flame spread potential the spread limit was set at 75. A rating of 0-25 is reported as a Class A rating, and a rating of 26-75 is reported as a Class B rating. Because the Steiner Tunnel Test evaluated carpet mounted on a wall and ceiling, the flame spread results obtained in this
