Modification:
The 1st paragraph of EN 13611:2019, Clause 1 is replaced by:
This document specifies the safety, design, construction, and performance requirements and testing for automatic vent valves for burners and appliances burning one or more gaseous fuels, hereafter referred to as “valves”.
This document is applicable to valves with declared maximum inlet pressures up to and including 500 kPa and of nominal connection sizes up to and including DN 100.
Addition:
This document is applicable to:
-   electrically actuated valves;
-   valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy;
-   valves fitted with open position indicator switches.

EN 13611:2019, Abschnitt 1, gilt mit folgender Änderung und Ergänzung:
Änderung:
Der erste Absatz von EN 13611:2019, Abschnitt 1, wird ersetzt durch:
Dieses Dokument legt die Sicherheits , Auslegungs , Konstruktions- und Leistungsanforderungen sowie die Prüfung von automatischen Abblaseventilen für Brenner und Brennstoffgeräte für einen oder mehrere gasförmige Brennstoffe, nachstehend als „Ventile“ bezeichnet, fest.
Dieses Dokument gilt für Ventile mit einem angegebenen höchsten Eingangsdruck bis einschließlich 500 kPa und mit Anschlussnennweiten bis einschließlich DN 100.
Ergänzung:
Dieses Dokument gilt für:
—   elektrisch betätigte Ventile;
—   Ventile, die durch Steuermedien betätigt werden, wenn die Steuerventile für diese Medien elektrisch betätigt werden; aber nicht für externe elektrische Elemente, die das Steuersignal oder die Antriebsenergie schalten;
—   Ventile mit Meldeschaltern für die offene Stellung.
Der vierte Absatz von EN 13611:2019, Abschnitt 1, entfällt.
