Safety and control devices for burners and appliances burning gaseous and/or liquid fuels - Valve proving systems for automatic shut-off valves
EN 13611:2019, Clause 1 is replaced by following:
This document specifies the safety, design, construction and performance requirements, and testing for valve-proving systems, hereafter referred to as “VPS”, intended for use with gas burners and gas-burning appliances burning one or more gaseous fuels.
This document applies to all types of VPS used for the automatic detection of leakage in a gas burner section having at least two automatic shut-off valves, and which give a signal if the leakage of one of the valves, the piping in-between the valves or of the VPS itself and its components exceeds the detection limit.
This document applies to VPS for gases with a maximum inlet pressure up to and including 500 kPa.
This document does not apply to VPSs for use in explosive atmospheres.
This document is applicable to AC and DC supplied VPS (for VPS supplied by stand-alone battery system, battery systems for mobile applications, or VPS which are intended to be connected to DC supply networks, see Annex I).
Sicherheits-, Regel- und Steuereinrichtungen für Brenner und Brennstoffgeräte für gasförmige und/oder flüssige Brennstoffe - Ventilüberwachungssysteme für automatische Absperrventile
EN 13611:2019, Abschnitt 1, wird durch Folgendes ersetzt:
Dieses Dokument legt die Sicherheits , Auslegungs , Konstruktions- und Leistungsanforderungen sowie die Prüfungen für Ventilüberwachungssysteme, im Folgenden „VPS“ genannt, für Gasbrenner und Gasgeräte für einen oder mehrere gasförmige(n) Brennstoff(e) fest.
Dieses Dokument gilt für alle Arten von VPS, die für die automatische Erkennung einer Leckage in einem Gasbrennerabschnitt mit mindestens zwei automatischen Absperrventilen eingesetzt werden und die ein Signal abgeben, wenn die Leckage eines der Ventile, der zwischenliegenden Verrohrung oder des VPS selbst den Empfindlichkeitsgrenzwert überschreitet.
Dieses Dokument gilt für VPS für Gase mit einem höchsten Eingangsdruck bis einschließlich 500 kPa.
Dieses Dokument gilt nicht für VPS zum Einsatz in explosionsgefährdeten Atmosphären.
Dieses Dokument gilt für mit Wechsel- und Gleichspannung betriebene VPS (für VPS, die durch unabhängige Batteriesysteme, Batteriesysteme für die Anwendung in Fahrzeugen oder VPS für den Anschluss an Gleich¬spannungsnetze betrieben werden, siehe Anhang I).
Dispositifs de commande et de sécurité pour brûleurs à gaz et appareils à gaz - Systèmes de contrôle d'étanchéité pour robinets automatiques de sectionnement
L'article 1 de l'EN 13611:2019 est remplacé par ce qui suit :
Le présent document précise les exigences pour la sécurité, la construction et le fonctionnement ainsi que les essais applicables aux systèmes de contrôle d'étanchéité, dénommés ci-après SCE, prévus pour une utilisation avec les brûleurs et appareils à gaz.
Le présent document s'applique aux SCE qui sont utilisés pour une détection automatique de fuite sur une partie de la ligne gaz d'un brûleur ayant au moins deux robinets, et qui donnent un signal si l'un des deux robinets, la ligne entre les 2 robinets ou le SCE lui-même, présente un débit de fuite supérieur au niveau de détection du SCE.
Le présent document s'applique aux SCE pour les combustibles gazeux ayant une pression d’entrée maximale allant jusqu'à 500 kPa inclus.
Le présent document ne s'applique pas aux SCE prévus pour être utilisés en atmosphère explosive.
Le présent document couvre les SCE alimentés en courant alternatif et en courant continu (pour les SCE alimentés par des systèmes de batterie autonomes, des systèmes de batterie pour applications mobiles ou des systèmes destinés à être connectés au réseau d'alimentation en courant continu, voir Annexe I).
Varnostne in nadzorne naprave za gorilnike in aparate na plin in/ali tekoča goriva - Sistemi za preskušanje avtomatskih zapornih ventilov
Ta evropski standard določa zahteve v zvezi z varnostjo, izdelavo in delovanjem za sisteme za preskušanje ventilov (VPS), namenjene za uporabo v plinskih gorilnikih in plinskih aparatih. Prav tako opisuje preskusne postopke za preverjanje skladnosti s temi zahtevami ter zagotavlja potrebne informacije za kupca in uporabnika.
Ta evropski standard se uporablja za vse vrste sistemov za preskušanje ventilov, ki se uporabljajo za samodejno zaznavanje uhajanja v plinskih gorilnikih z vsaj dvema ventiloma, ki so zasnovani v skladu s standardom EN 161 in uporabnika opozorijo s signalom, če uhajanje v enem od ventilov preseže mejo zaznavnosti.
Ta evropski standard se uporablja za sisteme za preskušanje ventilov z najvišjim delovnim tlakom do vključno 500 kPa za uporabo v sistemih, ki uporabljajo plinasta goriva prve, druge ali tretje družine.
Ta evropski standard se ne uporablja za sisteme za preskušanje ventilov, ki se uporabljajo v eksplozivnih atmosferah.
Ta evropski standard se uporablja za sisteme za preskušanje ventilov, ki se napajajo z izmeničnim ali enosmernim tokom (za sisteme za preskušanje ventilov, ki se napajajo s samostojnim akumulatorskim sistemom, akumulatorskimi sistemi za premične aplikacije ali s sistemi, ki so namenjeni za priključitev na omrežja z enosmernim tokom, glej dodatek I).
Določbe za kontrolo proizvodnje niso del tega evropskega standarda.
