    • A holder for a fuse or the like of the type which is insertable into a hole in a mounting plate and fastened to the mounting plate comprises an elongate housing dimensioned to be axially inserted in the hole in the mounting plate and having at one end a flange portion which abuts the mounting plate upon full insertion of the housing in the hole. A resiliently deformable sleeve is mounted on the housing adjacent the flange portion and the sleeve has an outer diameter slightly greater than that of the mounting plate hole. During insertion of the housing in the mounting plate hole, the sleeve makes sliding contact with the wall of the hole thereby causing inward deformation of the sleeve to an extent sufficient to cause the sleeve to exert radially outward pressure against the wall of the hole to thereby frictionally fasten the holder to the mounting plate. The sleeve has sufficient resilience to enable it to be radially inwardly compressed in response to insertion of the housing in the mounting plate hole so that the holder can be quickly fastened to the mounting plate by simply inserting the holder housing in the mounting plate hole.

    • The invention relates to a method and a device for testing the fire hazard of a material. According to one embodiment of the method, a plane region of the surface of a specimen made of the material is brought in contact for at most a predetermined contact time with a glow wire, which has been heated to a predetermined temperature. Image data of the specimen are furthermore acquired by at least a first camera at least while the specimen is in contact with the glow wire. Image processing of the acquired image data of the specimen is furthermore carried out, preferably in realtime, ignition of the specimen by the glow wire being detected if applicable. A first duration is then determined, which corresponds to the length of time between the application of the tip of the glow wire on the specimen and the ignition of the specimen. Furthermore, according to one embodiment of the invention, a second duration may if applicable be determined by means of the image processing of the acquired image data of the specimen, the second duration corresponding to the length of time between the application of the tip of the glow wire on the specimen and the end of the ignition of the specimen. The method and the device are suitable in particular for carrying out tests to assess the fire hazard of materials according to the standards EN 60695-2-10, -12 and -13.

    • 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.
