Leak detection systems - Part 2: Requirements and test/assessment methods for pressure and vacuum systems

This European Standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits (leak detector) based on the measurement of pressure change. Leak detection kits are intended to be used with double skin, underground or above ground, pressurized or non-pressurized, tanks or pipework designed for water polluting liquids/fluids. The kits are usually composed of:
-   measuring device;
-   evaluation device;
-   alarm device;
-   pressure generator;
-   pressure relief device;
-   liquid stop device;
-   condensate trap.

Leckanzeigesysteme - Teil 2: Anforderungen und Prüf-/Bewertungsmethoden für Über- und Unterdrucksysteme

Diese Europäische Norm legt Anforderungen an und die einschlägigen Prüf-/Bewertungsverfahren für Leckanzeiger (Leckdetektoren), die auf der Messung der Druckänderung basieren, fest. Leckanzeiger sind für den Einsatz an doppelwandigen, unterirdischen oder oberirdischen, druckbeaufschlagten oder nicht druck¬beaufschlagten Tanks oder Rohrleitungen für wassergefährdende Flüssigkeiten/Fluide bestimmt. Die Leckanzeiger bestehen in der Regel aus:
   Messeinrichtung;
   Auswerteeinrichtung;
   Alarmeinrichtung;
   Druckerzeuger;
   Überdruckventil;
   Flüssigkeitssperre;
   Kondensatgefäß.

Systèmes de détection de fuites - Partie 2 : Exigences et méthodes d'essai/d'évaluation des systèmes sous pression et à dépression

La présente Norme européenne spécifie les exigences et les méthodes d'essai/d'évaluation correspondantes applicables aux kits de détection de fuites (indicateur de fuites) fondées sur le mesurage de la variation de pression. Les kits de détection de fuites sont destinés à être utilisés avec des réservoirs ou des tuyauteries à double paroi, souterrains ou aériens, sous pression ou non, conçus pour des liquides/fluides polluant l'eau. Les kits sont généralement constitués des éléments suivants :
-   dispositif de mesurage ;
-   dispositif d'évaluation ;
-   dispositifs d'alarme ;
-   générateur de pression ;
-   dispositif de décharge de pression ;
-   dispositif d'arrêt de remplissage ;
-   purgeur de condensats.
