Abstract: A method of evaluating the flame retardancy of a sealing resin comprises a step of fusion cutting a heating element by causing the heating element to generate heat by the passage of electric current to a test sample of a molded body of the sealing resin including the heating element therein; a step of igniting the sealing resin by continuing the passage of electric current even after the heating element is fusion-cut; and a step of measuring voltage and/or current applied in a period from when the heating element is fusion-cut to the ignition of the sealing resin. The test sample is used in the method of evaluating the flame retardancy and provided with a heating wire; conducting terminals made of metal having an electric resistance lower than the heating wire and connected to both ends of the heating wire; and a sealing resin layer covering the outer periphery of the heating wire. The evaluation can be performed on the flame retardancy of the sealing resin used for the electronic equipment based on its actual use.

Abstract: 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.

Abstract: A sensor 11 detects the acoustic pressure at a first location in a combustion chamber 7 of a test rig 1 and produces an input signal which is a function of the acoustic pressure. A controller 13 receives the input signal and produces an output signal which is a function of the input signal. An acoustic actuator (16-18) receives the output signal and introduces into the combustion chamber 7 at a second location an acoustic pressure which is a function of the output signal. The acoustic actuator may comprise a fuel injector 18 or a loudspeaker. By using an appropriate control algorithm, acoustic boundary conditions corresponding to a particular gas turbine combustion chamber may be produced, at least in a certain frequency range.

Abstract: The fire resistance of components normally subject to a standard flame test is evaluated using low temperature model tests. Reynolds number, Froude number, the pressure ratio of the flame to the surrounding atmosphere are matched in the modelling parameters and account is taken of the Prandtl number. Also, the model flow is controlled so as to match the change of momentum flux ratio in the flow through the burner used in a standard flame test. The method allows testing of easily produced model components at temperatures less than 90° C., with savings of cost and time.

Abstract: A method for determining flame retardance of polymer compositions includes subjecting a plurality of specimens of a polymer composition to a flame test and performing a statistical analysis of the data obtained. The statistical analysis includes determining the probability of at least one possible outcome of the flame test. The probability of possible outcomes provides a measure of the flame retardance of the polymer composition. A preferred flame test is the UL-94 flame test.
