Specification for portable electrical apparatus designed to measure combustion flue gas parameters of heating appliances - Part 1: General requirements and test methods
This European Standard covers apparatus for measuring gas concentrations and other combustion parameters, as used in the installation and maintenance of heating appliances. Such apparatus may be used for testing the performance of appliances for different types of fuels, either by the installer, maintenance engineer or inspector. The apparatus may consist of different functional modules, which may be tested separately for complying with this standard and will be combined in different ways according to the different applications. The apparatus shall comply with requirements as specified in EN 50379 2 and/or EN 50379 3. This European Standard specifies general requirements for the construction, testing and performance of portable spot reading apparatus designed to give an assessment of specific combustion flue gas parameters, such as concentration of gaseous compounds, temperature and/or pressure, to check the combustion performance of heating appliances for domestic residential and commercial applications, using commercially available fuels. This standard excludes apparatus for – continuous emission, safety monitoring and control, and – use in vessels with an international load line. NOTE 1 When this apparatus is used in industrial premises national regulations may apply. NOTE 2 Apparatus may contain functional modules which are not covered by this standard e.g. measurement of smoke spot number (see Annex A of EN 267).
Anforderungen an tragbare elektrische Geräte zur Messung von Verbrennungsparametern von Heizungsanlagen - Teil 1: Allgemeine Anforderungen und Prüfverfahren
Diese Europäische Norm gilt für Geräte zur Bestimmung von Gaskonzentrationen und anderen Verbrennungsparametern, wie sie bei der Installation und Wartung von Heizungsanlagen verwendet werden. Diese Geräte werden zur Bestimmung des Betriebsverhaltens von Heizungsanlagen für verschiedene Brennstoffe sowohl vom Heizungsbauer/Installateur, Wartungsdienst oder bevollmächtigten Inspektor benutzt. Die Geräte können verschiedene Funktionsmodule enthalten, deren Konformität in dieser Norm einzeln geprüft werden darf und die in verschiedenen Varianten, entsprechend der Anwendungsmöglichkeiten kombiniert werden dürfen. Diese Geräte müssen den Anforderungen der EN 50379-2 und/oder EN 50379-3 entsprechen. Diese Europäische Norm legt allgemeine Anforderungen an Konstruktion, Prüfung und Betriebsverhalten für tragbare Geräte für Kurzzeitmessungen fest, die spezifische Abgasparameter wie die Konzentration von einzelnen Gaskomponenten, die Temperatur und/oder den Druck bei Verbrennungsprozessen ermitteln, um das Betriebsverhalten von Heizungsanlagen in privaten Haushalten und Industrieanwendungen zu beurteilen, die im Handel erhältliche Brennstoffe verfeuern. Diese Europäische Norm gilt nicht für – kontinuierliche Abgasanalyse, sicherheitsgerichtete Messung und Regelung, – den Einsatz auf Schiffen mit internationaler Freibordmarke. ANMERKUNG 1 Wenn diese Geräte in industriellen Anwendungen benutzt werden, müssen nationale Richtlinien beachtet werden. ANMERKUNG 2 Geräte können Funktionsmodule enthalten, die nicht durch diese Norm beschrieben werden, zum Beispiel die Messung der Rußzahl (siehe EN 267, Anhang A).
