IEC 62282-4-101:2022 deals with safety of fuel cell power systems for propulsion other than road vehicles and auxiliary power units (APU). This part of IEC 62282 covers safety requirements for fuel cell power systems intended to be used in electrically powered industrial trucks as defined in ISO 5053-1.except for: rough-terrain trucks; non-stacking low-lift straddle carriers; stacking high-lift straddle carriers; rough-terrain variable-reach trucks; slewing rough-terrain variable-reach trucks; variable-reach container handlers; pedestrian propelled trucks. This document applies to gaseous hydrogen-fueled fuel cell power systems and direct methanol fuel cell power systems for electrically powered industrial trucks. This document applies to DC type fuel cell power systems, with a rated output voltage not exceeding 150 V DC for indoor and outdoor use.This second edition cancels and replaces the first edition published in 2014.This edition includes the following significant technical changes with respect to the previous edition: - revision of the title of this document; - revision of reference standards; - addition of new subclauses (4.3, 4.14.5, 4.15.3, 4.15.4, 4.16, 5.6, and 5.23); - previous 4.15 was revised as “4.16 Risk assessment and risk reduction”; - revision of 4.6 3), access to the manual shutoff valve; - revision of requirements for battery terminals that are threaded (4.14.10.1); - revision of requirements for double layer capacitors (4.14.10.2); - revision of external leakage test (5.5) and ultimate strength test (5.7); - revision of temperature limits on capacitors depending on the temperature rating of the material (Table 3); - revision of markings that are not relevant (Clause 7); - added “Significant hazards, hazardous situations and events dealt with in this document” as a new informative annex LIEC 62282-4-101:2022 traite des systemes a piles a combustible pour la propulsion, autres que les vehicules routiers et groupes auxiliaires de puissance (GAP). La presente partie de l’IEC 62282 couvre les exigences de securite relatives aux systemes a pile a combustible destines a etre utilises sur des chariots de manutention electriques, definies dans l’ISO 5053-1 a l’exception des chariots suivants: chariots tout-terrain; chariots cavaliers elevateurs non gerbeurs; chariots cavaliers elevateurs gerbeurs; chariots tout-terrain a portee variable; chariots tout-terrain rotatifs a portee variable; chariots porte-conteneur a portee variable; chariots a propulsion manuelle. Le present document s’applique aux systemes a pile a combustible utilisant de l’hydrogene gazeux et a ceux utilisant du methanol direct pour les chariots de manutention electriques.Le present document s’applique aux systemes a pile a combustible de type a courant continu, d’une tension de sortie assignee d’au maximum 150 V en courant continu pour utilisation a l’interieur et a l’exterieur. Cette deuxieme edition annule et remplace la premiere edition parue en 2014.Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: - revision du titre du present document; - revision des normes de reference; - ajout de nouveaux paragraphes (4.3, 4.14.5, 4.15.3, 4.15.4, 4.16, 5.6 et 5.23); - renumerotation du paragraphe 4.15 de la version precedente en "4.16 Appreciation du risque et reduction du risque"; - revision de 4.6 3) concernant l’acces au robinet d’arret manuel; - revision des exigences relatives aux bornes filetees de la batterie (4.14.10.1); - revision des exigences relatives aux condensateurs a double couche (4.14.10.2); - revision de l’essai de fuites externes (5.5) et de l’essai de resistance a la rupture (5.7); - revision des limites de temperature des condensateurs dependant des caracteristiques assignees de tenue en temperature du materiau (Tableau 3); - revision des marquages non pertinents (Article 7); - ajout d’une nouvelle annexe informative (Annexe B) "Phenomenes dangereux significatifs, situations et evenements dangereux traites dans le present document".
