ČSN EN 12312-12 Tato evropská norma stanovuje technické požadavky k minimalizování nebezpečí uvedených v kapitole 4, která mohou nastat během uvádění do provozu, provozu a údržby zařízení pro obsluhu pitnou vodou, pokud jsou používána tak, jak bylo určeno, včetně nesprávného použití důvodně předvídatelného výrobcem, které se provádějí v souladu se specifikacemi danými výrobcem nebo jeho autorizovaným zástupcem. Tato část také bere v úvahu některé požadavky uznané jako základní oprávněnými orgány, výrobci letadel a pozemních zařízení pro letadla (ground support equipment; GSE), jakož i leteckými společnostmi a odbavovacími agenturami. Tato norma platí pro: a) samojízdná vozidla pro obsluhu pitnou vodou, b) přívěsná vozidla pro obsluhu pitnou vodou, c) pohyblivé části rampových integrovaných systémů navržené pro obsluhu letadel a určené k používání za podmínek uvedených v EN 1915-1:2013, kapitola 1. Nejsou poskytnuty žádné další požadavky na hluk a vibrace kromě těch v EN 1915-3 a EN 1915-4. Poznámka: EN 1915-3 a EN 1915-4 poskytují obecné požadavky na hluk a vibrace pro GSE. Tato část EN 12312 není vhodná pro zařízení pro obsluhu pitnou vodou, která byla vyrobena před datem vydání této normy v CEN. Tato část EN 12312 při použití ve spojení s EN 1915-1, EN 1915-2, EN 1915-3 a EN 1915-4 stanovuje požadavky na zařízení pro obsluhu pitnou vodou.
