Leak detection systems - Part 2: Requirements and test/assessment methods for pressure and vacuum systems
This document gives requirements and the corresponding test/assessment methods applicable to leak detector based on the measurement of pressure change. Leak detectors are intended to be used with double skin, underground or above ground, pressurized or non-pressurized, tanks or pipe designed for water polluting liquids/fluids. The leak detectors 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
Dieses Dokument legt Anforderungen an und die einschlägigen Prüf-/Bewertungsverfahren für Leckdetektoren, die auf der Messung der Druckänderung basieren, fest. Leckdetektoren sind für den Einsatz an doppelwandigen, unterirdischen oder oberirdischen, druckbeaufschlagten oder nicht druckbeaufschlagten Tanks oder Rohren für wassergefährdende Flüssigkeiten/Fluide bestimmt. Die Leckdetektoren 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
Le présent document spécifie les exigences et les méthodes d'essai/d'évaluation correspondantes applicables aux détecteurs de fuites fondées sur le mesurage de la variation de pression. Les détecteurs 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 détecteurs de fuites 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.
