IEC 62485-4:2015 applies to the safety aspects associated with the accommodation, the arrangements of circuits and the operation of secondary valve-regulated lead-acid cells and batteries in portable appliances. Requirements are specified which oblige the manufacturers of appliances and secondary batteries to prevent the misuse of batteries in the course of operation to provide protective measures avoiding injury to persons in case of battery failure and to provide sufficient information to users. This standard does not apply to secondary cells and batteries containing alkaline or other non-acid electrolytes. This first edition cancels and replaces the first edition of IEC TR 61056-3 published in 1991. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the IEC TR 61056-3: a) updating of the requirements, and harmonisation of the text for consistency with the IEC 62485 series.

Technical committeeTypeAcronymIEC 62485-1:2015CommitteePublished year2015Description
IEC 62485-1:2015 specifies the basic requirements for secondary batteries and battery installations. The requirements regarding safety, reliability, life expectancy, mechanical strength, cycle stability, internal resistance, and battery temperature, are determined by various applications, and this, in turn, determines the selection of the battery design and technology. In general, the requirements and definitions are specified for lead-acid and nickel-cadmium batteries. For other battery systems with aqueous electrolyte, the requirements may be applied accordingly. The standard covers safety aspects taking into account hazards associated with: - electricity (installation, charging, discharging, etc.); - electrolyte; - inflammable gas mixtures; - storage and transportation.

IEC 62477-2:2018 applies to power electronic converter systems (PECS) and equipment, their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages from 1 000 V AC or 1 500 V DC up to 36 kV AC or 54 kV DC.
This document can also be used as a reference standard for product committees producing product standards foradjustable speed electric power drive systems (PDS),
standalone uninterruptible power systems (UPS), and
stabilized DC power supplies.
For PECS for which no product standard exists, this document provides minimum requirements for safety aspects.This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems and equipment for solar, wind, tidal, wave, fuel cell or similar energy sources.
According to IEC Guide 104, one of the responsibilities of technical committees is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of their product standards.
This document
establishes a common terminology for safety aspects relating to PECS and equipment,
establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS,
establishes a common basis for minimum safety requirements for the PEC portion of products that contain PEC,
specifies requirements to reduce risks of fire, electric shock, thermal, energy and mechanical hazards, during use and operation and, where specifically stated, during service and maintenance,
specifies minimum requirements to reduce risks with respect to pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer,
establishes an arc fault rating label requirement with testing instructions for PEC and PECS, and
covers power electronic converters and systems in open type design, which are catalog (pre-defined commercially available) power electronic converters and systems or engineered solutions from same.
This document does not covertelecommunications apparatus other than power supplies to such apparatus,
functional safety aspects as covered by, for example, IEC 61508 (all parts),
electrical equipment and systems for railways applications and electric vehicles, and
power electronic converters and systems in open type design, which are – in their major part – dimensioned, designed and constructed according to the user’s individual requirements and specifications and follow power installation standards, for example IEC 61936-1. -
