EN 50121
EN 50121 legt Grenzwerte und Messverfahren für die Störaussendung und Störfestigkeit von elektrischen und elektronischen Einrichtungen, die für die Verwendung in Schienenfahrzeugen vorgesehen sind, fest. Die Festlegungen gelten in Verbindung mit DIN EN 50121-1 (VDE 0115-121-1) und werden für den Frequenzbereich von 0 Hz bis 400 GHz spezifiziert. Die Störfestigkeitsprüfungen umfassen die Entladung statischer Elektrizität, einstrahlende hochfrequente elektromagnetische Felder einschließlich derjenigen von digitalen Funktelefonen beziehungsweise Handys, schnelle transiente elektrische Störgrößen (Impulsgruppen, Burst), Stoßspannungen sowie leitungsgeführte Störgrößen, die durch hochfrequente Felder induziert werden.
