This European Standard gives requirements and the corresponding test\/assessment methods applicable to leak detection kits based on the drop of the liquid level in the leak detection liquid reservoir. Leak detection kits are intended to be used with double skin, underground or above ground, non-pressurized, tanks designed for water polluting liquids.<\/p>\n
The liquid leak detection kits are usually composed of:<\/p>\n
sensing device (liquid sensor);<\/p>\n<\/li>\n
evaluation device;<\/p>\n<\/li>\n
alarm device.<\/p>\n<\/li>\n<\/ul>\n
