FprEN 764-7

Pressure equipment - Part 7: Safety systems for unfired pressure equipment

This document specifies the requirements for safety systems which protect a vessel, a system of vessels, piping, accessories or assemblies from exceeding operating conditions.
It is also applicable to safety related indicators and alarms, signals and warning devices when used in safety systems.
Equipment connected together by piping of adequate capacity, free from potential blockages and which does not contain any valve that can isolate any part from the safety system, may be considered as a single pressure system when considering the requirements for overpressure protection.
Safety systems include the interconnections between the equipment to be protected and any discharge location. This location can either be an outlet to atmosphere or the entry into a closed disposal system.
NOTE   The scope of this document and its relationship to the safety accessories and other protective devices described in the Pressure Equipment Directive are shown in Annex E.

Druckgeräte - Teil 7: Sicherheitseinrichtungen für unbefeuerte Druckgeräte

Dieses Dokument legt die Anforderungen an Sicherheitseinrichtungen zum Schutz von Druckbehältern, Systemen von Druckbehältern, Rohrleitungen, Ausrüstungsteilen und Baugruppen vor unzulässigen Betriebsbedingungen fest.
Sie beinhaltet auch sicherheitsrelevante Anzeige- und Alarmeinrichtungen, Signale und Warneinrichtungen, sofern diese in Sicherheitseinrichtungen verwendet werden.
Geräte, die über Rohrleitungen ausreichenden Querschnitts, ohne eventuelle Sperren und ohne irgendein Ventil, das Bereiche des Sicherheitssystems abtrennen kann, mit Systemen verbunden sind, dürfen in Bezug auf die Anforderungen an die Absicherung gegen Drucküberschreitung als einfaches Drucksystem betrachtet werden.
Sicherheitseinrichtungen schließen die Verbindungen zwischen dem zu schützenden Gerät und der gesamten Abblaseleitung ein. Es kann sich dabei um eine Ableitung in die Atmosphäre oder in ein geschlossenes Entsorgungssystem handeln.
ANMERKUNG   Der Anwendungsbereich dieses Dokuments, bezogen auf die in der Druckgeräterichtlinie beschriebenen Ausrüstungsteile mit Sicherheitsfunktion und weitere Einrichtungen mit Schutzfunktion, ist in Anhang E dargestellt.

Équipements sous pression - Partie 7 : Systèmes de sécurité pour équipements sous pression non soumis à la flamme

Le présent document prescrit les exigences applicables aux systèmes de sécurité qui protègent un récipient, un système de récipients, une tuyauterie, des accessoires ou des ensembles vis-à-vis de dépassements des conditions de fonctionnement.
Il est également applicable aux indicateurs et alarmes liés à la sécurité, aux dispositifs de signalisation et d’avertissement lorsqu’ils sont utilisés en tant que systèmes de sécurité.
Les équipements raccordés les uns aux autres dans un système par des tuyauteries de débit adéquat, exempts de blocages potentiels et ne comprenant pas d’appareil de robinetterie susceptible d'isoler une partie quelconque, peuvent être considérés comme un système sous pression unique eu égard aux exigences de protection vis à vis des surpressions.
Les systèmes de sécurité comprennent les interconnexions entre les équipements devant être protégés et tout point de décharge. Cet emplacement peut être un orifice de sortie à l'atmosphère ou le raccordement à un système de récupération fermé.
NOTE   Le domaine d’application du présent document et ses relations avec les accessoires de sécurité et les autres dispositifs de protection de la Directive Équipements sous pression sont indiqués en Annexe E.
