MT 301 - TC 105/MT 301

IEC 62282-4-101:2022 is available as IEC 62282-4-101:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
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

IEC 62282-4-102:2017 covers performance test methods of fuel cell power systems intended to be used for electrically powered industrial trucks. The scope of this document is limited to electrically powered industrial trucks. This document applies to gaseous hydrogen-fuelled fuel cell power systems and direct methanol fuel cell power systems for electrically powered industrial trucks. This document covers fuel cell power systems whose fuel source container is permanently attached to either the industrial truck or the fuel cell power system. 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.

IEC 62282-4-101:2014 covers safety requirements for fuel cell power systems intended to be used in electrically powered industrial trucks. This standard is limited to electrically powered industrial trucks and is applicable to material-handling equipment, e.g. forklifts. It applies to gaseous hydrogen-fuelled fuel cell power systems and direct methanol fuel cell power systems for electrically powered industrial trucks.
