Gas/air ratio controls for gas burners and gas burning appliances - Part 2: Electronic types

This European Standard specifies the safety, construction and performance requirements for electronic gas/air ratio control systems (GARCs) intended for use with gas burners and gas burning appliances. It also describes the test procedures for evaluating these requirements and specifies information necessary for installation and use.
This standard is only applicable to closed loop gas/air ratio controls (see 3.1) and does not differentiate into classification by heat input.
This standard applies to electronic GARCs that can be tested independently, as well as part of an appliance or a gas burner.

Gas-Luft-Verbundregeleinrichtungen für Gasbrenner und Gasgeräte - Teil 2: Elektronische Ausführung

Diese Europäische Norm legt die Anforderungen an die Sicherheitstechnik, die Konstruktion und die Ausführung für elektronische Gas-Luft-Verbundregeleinrichtungen (GARC) fest, die für den Gebrauch mit Gasbrennern und Gasgeräten bzw. -anlagen bestimmt sind. Außerdem werden die Prüfverfahren zur Bewertung dieser Anforderungen sowie die für Installation und Gebrauch notwendigen Informationen festgelegt.
Diese Norm gilt nur für geschlossene Gas-Luft-Verbundregelkreise (siehe 3.1) und unterscheidet nicht hinsichtlich Wärmeleistungsklassen.
Die vorliegende Norm gilt für elektronische GARC, die für sich alleine, aber auch als Teil eines Gerätes bzw. einer Anlage oder eines Gasbrenners geprüft werden können.

Dispositifs de régulation du rapport air/gaz pour brûleurs à gaz et appareils à gaz - Partie 2: Dispositifs électroniques

La présente norme précise les spécifications minimales de sécurité, de construction et de fonctionnement des dispositifs électroniques de régulation du rapport air/gaz destinés à équiper des brûleurs à gaz et des appareils à gaz. Elle décrit aussi les modes opératoires d'essai permettant de vérifier la conformité à ces exigences ainsi que les informations nécessaires à l'installation et à l'utilisation.
La présente norme s'applique uniquement aux dispositifs de régulation du rapport air/gaz à boucle fermée (voir 3.1) et ne présente pas de classification par débit calorifique.
La présente norme s'applique aux dispositifs électroniques du rapport air/gaz qui peuvent être soumis à essai séparément, comme faisant partie d'un appareil ou d'un brûleur à gaz.
