Abstract

The image data capture of a test piece is performed with at least one first camera. A reference point of the test piece is determined by processing the image data recorded with the at least one first camera. A burner is positioned at a prescribed first distance from the reference point for the flame exposure of the test piece. At least one second camera may also detect whether the test piece exposed to a flame is burning or incandescing. At least one third camera may be used for monitoring the burner flame and at least one fourth camera may be used for determining whether the test piece drips while burning. Furthermore, at least one detector may used for detecting whether the drips ignite a pad of wadding positioned under the test piece.
