NOTE 1 Les accessoires démontables par l’utilisateur qui sont installés sur le porteur de charge ou sur les bras de fourche ne sont pas considérés comme faisant partie intégrante du chariot.
Le présent document spécifie les prescriptions techniques supplémentaires relatives à la prévention de l’inflammation d’une atmosphère explosive de gaz, vapeurs, brouillards ou poussières inflammables, dus aux chariots de manutention du groupe d’appareil II et de la catégorie d’appareil 2G, 3G, 2D ou 3D.
NOTE 2 La relation entre une catégorie d’appareil (désignée ci-après par « catégorie ») et la zone correspondante (classification de zone) est illustrée à l’Annexe B (informative).
Le présent document ne s'applique pas :
- aux chariots du groupe d’appareil I ;
- aux chariots du groupe d’appareil II, catégorie d’appareil 1 ;
- aux chariots destinés à être utilisés en atmosphères explosibles constituées de mélanges hybrides ;
- aux systèmes de protection.
Le présent document ne s’applique pas aux chariots destinés à être utilisés en atmosphères explosibles contenant du sulfure de carbone (CS2), du monoxyde de carbone (CO) et/ou de l’oxyde d’éthylène (C2H4O), en raison des propriétés spécifiques de ces gaz.
Les prescription techniques relatives aux batteries lithium-ion et aux piles à combustibles en tant que sources d’énergie ne sont pas données dans le présent document en raison de leurs phénomènes dangereux spécifiques.
Vozila za talni transport - Varnostne zahteve in preverjanje - Dodatne zahteve za delovanje v potencialno eksplozivnih atmosferah
Ta dokument se uporablja za vozila za talni transport z lastnim pogonom ter ročno in napol ročno gnana vozila, opredeljena v standardu ISO 5053-1:2020, vključno z njihovimi napravami za delo z bremenom in priključki (v nadaljevanju: vozila), ki so namenjena za uporabo v potencialno eksplozivnih atmosferah.
OPOMBA 1: Priključki, nameščeni na nosilec bremena ali na vilice, ki jih lahko odstrani uporabnik, se ne obravnavajo kot del vozila.
Ta dokument določa dodatne tehnične zahteve za preprečevanje vžiga eksplozivne atmosfere vnetljivih plinov, hlapov, meglic ali prahu s strani vozil za talni transport skupine opreme II in kategorije opreme 2G, 3G, 2D ali 3D.
OPOMBA 2: Razmerje med kategorijo opreme (v nadaljevanju: kategorija) in ustreznim območjem (klasifikacija območja) je prikazano v informativnem dodatku B.
Ta dokument se ne uporablja za:
– vozila skupine opreme I;
– vozila skupine opreme II in kategorije opreme 1;
– vozila, namenjena uporabi v potencialno eksplozivnih atmosferah s hibridnimi mešanicami;
– varnostne naprave.
Ta dokument se ne uporablja za vozila, namenjena za uporabo v potencialno eksplozivnih atmosferah ogljikovega disulfida (CS2), ogljikovega monoksida (CO) in/ali etilenoksida (C2H4O) zaradi posebnih lastnosti teh plinov.
Tehnične zahteve v zvezi z litij-ionskimi baterijami in gorivnimi celicami kot viri energije niso podane v tem dokumentu zaradi posebnih tveganj, ki jih predstavljajo.
