La présent document fixe les exigences et les méthodes d'essai/d'évaluation applicables aux détecteurs de fuites, fondées sur la baisse du niveau de liquide dans le réservoir de liquide de la détection de fuites. Les détecteurs de fuites sont destinés à être utilisés avec des réservoirs à double paroi, souterrains ou aériens, sous pression ou non, conçus pour des liquides polluant l'eau.
Les détecteurs à liquide de fuites sont généralement constitués des éléments suivants :
- dispositif de détection (détecteur de liquide) ;
- dispositif d'évaluation ;
- dispositifs d'alarme.
