Resumen:
The document specifies the safety, constructional and performance requirements for valve proving systems for gas burners and gas appliances. It applies to all types of VPS which are used for automatic detecting of leakage in a gas burner section heaving at least two valves designed according to EN 161 and give a signel, if the leakage of one valve exceeds the detection limit.
Das Dokument legt Sicherheitsanforderungen, Auslegungs- und Leistungsanforderungen an Ventilüberwachungssysteme für Gasbrenner und Gasgeräte fest. Sie gilt für alle Arten von Ventilüberwachungssystemem, die für die automatische Überwachung der Leckage in einem Gasbrennerabschnitt mit mindestens zwei Absperrventilen nach EN 161 eingesetzt werden und ein Signal abgeben, wenn die Leckage eines Ventils die Empfindlichkeitsgrenze überschreitet.
