Les kits de revêtements intérieurs et les kits de revêtements extérieurs protecteurs de fuites, destinés à être utilisés après installation pour créer un espace interstitiel ou un espace de confinement des fuites dans des réservoirs à simple paroi, aériens ou souterrains, sans pression, conçus pour des liquides polluant l'eau. Le kit est destiné à être utilisé conjointement aux kits de détection de fuites couverts par les prEN 13160-2 à prEN 13160-4.
Sistemi za kontrolo tesnosti - 7. del: Zahteve in metode za preskušanje in ocenjevanje vmesnih prostorov, zunanjih oblog in plaščev za zaznavanje netesnosti
Ta standard določa zahteve ter ustrezne metode za preskušanje in ocenjevanje, ki se uporabljajo za komplete zunanjih oblog in komplete plaščev za zaznavanje netesnosti. Kompleti zunanjih oblog in kompleti plaščev za zaznavanje netesnosti so namenjeni za naknadno vgradnjo za ustvarjanje vmesnih prostorov ali zadrževalnikov pri dvoplaščnih, podzemnih ali nadzemnih rezervoarjih, ki so ali niso pod tlakom, in so zasnovani za tekočine, ki onesnažujejo vodo. Komplet se lahko uporablja samo skupaj s kompleti za kontrolo tesnosti, ki jih zajemajo standardi od prEN 13160-2 do prEN 13160-4.
