kSIST FprHD 60364-5-57:2022/oprAA:2025

Overview

The European standard kSIST FprHD 60364-5-57:2022/oprAA:2025 focuses on the selection and installation of electrical equipment related to stationary secondary batteries within low-voltage electrical installations. Prepared by CLC/TC 64 and submitted for enquiry in 2025, this amendment enhances the existing HD 60364-5-57:2022 by updating key clauses and annexes to better align with European practices. It addresses important safety considerations, operational definitions, and technical specifications for stationary secondary battery systems used in electricity supply infrastructures.

This standard is critical for ensuring safe, reliable, and harmonized installation practices across European member countries, supporting consistent implementation and protection against electrical hazards associated with secondary batteries.

Key Topics

• Definition Updates

  • Revised term “island mode” to clarify operational conditions where installations remain energized while disconnected from public supply.

• Removal of Certain Provisions

  • Deletion of subclauses on operation modes, protection against electric shock, isolation, detection means, and identification labels, streamlining the focus on essential safety and installation principles.

• Main Battery Characteristics & Selection

  • Relocated relevant sections on primary characteristics of stationary secondary batteries within the clause on selection and erection of electrical equipment to improve document structure.
  • Inclusion of standards such as EN IEC 62485-2 for short-circuit current considerations, especially for lead acid, Ni-MH, and Ni-Cd battery technologies.

• Protection Against Hazards

  • Expanded protection measures to explicitly cover risks related to fire and chemical hazards.
  • Emphasis on maintenance only by skilled or instructed personnel, highlighting the importance of trained professionals in battery system upkeep.

• Battery Accommodation Modifications

  • Updated terminology for improved clarity, replacing “personnel” with “persons” to emphasize all individuals involved.

• Special National Conditions

  • Inclusion of normative annexes addressing national or climatic characteristics affecting battery installations which cannot be harmonized across all European countries.
  • Guidance on how deviations (A-deviations) are managed to respect existing national regulations conflicting with this standard.

Applications

• Low-Voltage Electrical Installations

  • Applicable to stationary secondary battery systems such as those used for backup power, emergency supply, telecommunications, and energy storage units in residential, commercial, and industrial sectors.

• Electrical Equipment Installation

  • Assists engineers, installers, and safety experts in selecting appropriate battery technologies and implementing safe installation practices.

• Safety and Risk Management

  • Provides frameworks for mitigating electrical, chemical, and fire risks associated with stationary batteries in low-voltage systems.
  • Supports compliance with national and European electrical safety regulations, aiding in certification and legal adherence.

• Maintenance Protocols

  • Ensures correct maintenance approaches are adopted by authorized and trained personnel, reducing risks of accidents and prolonging battery service life.

Related Standards

• EN IEC 62485-2

  • Provides detailed requirements on safety measures, particularly for short-circuit current considerations in lead acid and nickel-based batteries integrated with this standard.

• HD 60364 Series

  • The broader standard family on low-voltage electrical installations, providing comprehensive guidelines on electrical system design, equipment selection, and installation practices.

• National Electrotechnical Standards

  • Adoption by European CENELEC members including Austria, France, Germany, UK, and others ensures this amendment harmonizes with various national regulations and practices.
