Abstract: A fixing device configured to fix a window pane of a window in a door leaf of a rail vehicle, the fixing device including a profile element; a window profile element; and a fastening device, wherein the fastening device is configured to fasten the profile element and the window profile element at each other by positive form locking and/or friction locking, wherein the profile element is formed from an elastic material, wherein the profile element includes a recess portion configured to fit around a border region of the window pane, a mounting portion configured to mount a first part of the fastening device on the profile element by positive form locking, a cover portion configured to cover the fastening device, and a connection portion configured to connect the cover portion to the window profile element by positive form locking.

Abstract: A method and a device for fatigue testing of photochromic, fluorescent or phosphorescent dye/dyes or of a mixture of at least two of them, in which a sample (3) containing photochromic, fluorescent or phosphorescent dye/dyes or a mixture of at least two of them is exposed to a predetermined number of cycles of luminous exposure to an excitation light beam (81), which evokes a color response of the photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them in the sample (3). Before and/or during and/or after each predetermined exposure to the excitation light beam (81), the sample (3) containing the photochromic, fluorescent or phosphorescent dye/dyes or of the mixture of at least two of them is exposed at least once to irradiation by an exposure light beam (71), due to which the dye/dyes is/are subject to fatigue loading.
