    • 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.
    • 本发明涉及一种用于测试材料的火灾危险的方法和装置。 根据该方法的一个实施例,由材料制成的试样的表面的平面区域与被加热到预定温度的辉光线接触至多预定的接触时间。 至少在样本与灼热丝接触时,至少由第一照相机获取样本的图像数据。 此外,优选实时地进行采集的图像数据的图像处理,如果适用,则通过检测到的灼热丝来点燃试样。 然后确定第一持续时间,其对应于在试样上灼热丝的尖端施加到样品的点火之间的时间长度。 此外,根据本发明的一个实施例,如果可以通过对所获取的样本的图像数据的图像处理来确定第二持续时间,则第二持续时间对应于应用所述样本的尖端之间的时间长度 试样上的灼热丝和试样的点火结束。 该方法和装置特别适合于根据标准EN 60695-2-10,-12和-13进行材料的火灾危险性测试。
