Test gases - Test pressures - Appliance categories

This document specifies the test gases, test pressures and categories of appliances relative to the use of gaseous fuels of the first, second and third families. It serves as a reference document in the specific standards for appliances that fall within the scope of the Council Directive on the approximation of the laws of Member States concerning gas appliances 2009/142/EC.
The standard makes recommendations for the use of the gases and pressures to be applied for the tests. The full procedure will be given in the corresponding appliance standards.
NOTE   The test gases and the test pressures specified in this standard are in principle intended to be used with all the appliances in order to establish conformity with the corresponding standards.
However, the use of some test gases and test pressures may not be appropriate in the following cases:
-   appliances with nominal heat input greater than 300 kW;
-   appliances constructed on site;
-   appliances in which the final design is influenced by the user;
-   appliances constructed for use with high supply pressures (notably direct use of the saturated vapour pressure).
In these cases, the specific appliance standards may specify other test conditions in order to establish compliance with their requirements.

Prüfgase - Prüfdrücke - Gerätekategorien

Diese Norm legt die Prüfgase, Prüfdrücke und Gerätekategorien für die Verwendung von Brenngasen der ersten, zweiten und dritten Gasfamilie fest. Sie gilt als übergeordnetes Dokument für die speziellen Gerätenormen, die unter den Geltungsbereich der Richtlinie 2009/142/EG des Rates zur Angleichung der Rechtsvorschriften der Mitgliedstaaten für Gasverbrauchseinrichtungen fallen.
Die Norm enthält Empfehlungen zur Verwendung von Gasen und Drücken bei der Durchführung der Prüfungen. Das vollständige Verfahren wird in den entsprechenden Gerätenormen angegeben.
ANMERKUNG   Die Prüfgase und Prüfdrücke, die in dieser Norm festgelegt werden, sind im Prinzip für sämtliche Geräte bestimmt, um die Konformität mit den entsprechenden Normen sicherzustellen.
Die Verwendung der Prüfgase und Prüfdrücke kann jedoch in folgenden Fällen nicht geeignet sein:
   Geräte mit einer Nennwärmebelastung über 300 kW;
   Geräte, die vor Ort erstellt werden;
   Geräte, deren Endausführung durch den Benutzer beeinflusst wird;
   Geräte, die für einen Betrieb bei hohen Versorgungsdrücken ausgelegt sind (insbesondere die direkte Verwendung des gesättigten Dampfdruckes).
In diesen Fällen können die einzelnen Gerätenormen weitere Prüfbedingungen festlegen, um die Konformität mit den Anforderungen der entsprechenden Normen sicherzustellen.

Gaz d'essais - Pressions d'essais - Catégories d'appareils

Cette norme définit les gaz d'essais, pressions d'essais et catégories d'appareils relatifs à l'utilisation de combustibles gazeux des première, deuxième et troisième familles. Elle sert de document de référence dans les normes particulières aux appareils qui entrent dans le champ d'application de la directive du Conseil relative au rapprochement des législations des États membres concernant les appareils à gaz (2009/142/CE).
La norme donne des recommandations pour l'utilisation des gaz et pressions à appliquer pour les essais. La procédure complète sera indiquée dans les normes particulières d'appareils correspondantes.
NOTE   Les gaz d'essais et les pressions d'essais spécifiés dans cette norme sont, en principe, destinés à être utilisés avec tous les appareils afin d'établir la conformité aux exigences des normes correspondantes.
Néanmoins l'utilisation des gaz d'essais et des pressions d'essais peut ne pas être appropriée dans les cas suivants :
-   appareils de débit calorifique nominal supérieur à 300 kW ;
-   appareils construits sur site ;
-   appareils dont la conception finale est déterminée par l'utilisateur ;
-   appareils construits pour l'utilisation avec de hautes pressions d'alimentation (notamment utilisation directe de la pression de vapeur saturante).
Dans ces cas, les normes particulières d'appareils peuvent spécifier d'autres conditions d'essais afin d'établir la conformité avec leurs exigences.

Preskusni plini - Preskusni tlaki - Kategorije naprav

Ta standard določa preskusne pline, preskusne tlake in kategorije naprav glede na uporabo plinastih goriv prve, druge in tretje družine. Uporablja se kot referenčni dokument v posebnih standardih za naprave, ki spadajo na področje uporabe Direktive Sveta o približevanju zakonodaj držav članic v zvezi z napravami na plinsko gorivo (90/396/ES). Standard daje priporočila za uporabo preskusnih plinov in preskusnih tlakov. Celoten postopek bo podan v ustreznih standardih naprave. OPOMBA:   Preskusni plini in preskusni tlaki, določeni v tem standardu, so načeloma namenjeni uporabi z vsemi napravami za ugotavljanje skladnosti z ustreznimi standardi. Vendar uporaba nekaterih preskusnih plinov in preskusnih tlakov morda ni primerna v naslednjih primerih: – za naprave z nazivno toplotno močjo več kot 300 kW; – za naprave, izdelane na mestu uporabe; – za naprave, pri katerih na končno zasnovo vpliva uporabnik; – za naprave, izdelane za uporabo z visokimi dovodnimi tlaki (zlasti pri neposredni uporabi nasičenega parnega tlaka). V teh primerih se lahko uporabijo posebni standardi za naprave, v katerih so določeni drugi preskusni pogoji za ugotavljanje skladnosti z njihovimi zahtevami.
