Powertrack systems - Part 21: Particular requirements for powertrack systems intended for wall and ceiling mounting

IEC 61534-21:2014 specifies the particular requirements and tests for PT systems intended for mounting on walls and/or ceiling. They may be installed flush or semi-flush, surface mounted, suspended or spaced away from the surface using fixing devices. This second edition cancels and replaces the first edition published in 2006 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Clauses 18 to 22 have been adapted to IEC 61534-1:2011 and include short-circuit test requirements;
- Additional classification, terms and requirements for wall powertrack (PT) systems mounted at the skirting level (close to the floor) position.
This publication is to be read in conjunction with IEC 61534-1:2011.

Cette deuxième édition annule et remplace la première édition parue en 2006 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Les Articles 18 à 22 ont été adaptés par rapport à l'IEC 61534-1:2011 et comprennent des exigences d'essai de court-circuit;
- Ajout de classifications, de termes et d'exigences pour les systèmes de conducteurs préfabriqués (PT, powertrack) pour mur montés en plinthe (proche du plancher).

Overview

EN 61534-21:2014 (IEC 61534-21:2014) defines particular requirements and tests for powertrack (PT) systems intended for wall and ceiling mounting. Published by CLC (CENELEC) as a European adoption of the IEC second edition, this standard updates and replaces the 2006 edition and must be used in conjunction with IEC/EN 61534-1:2011 (Part 1: General requirements). It covers PT systems installed flush, semi‑flush, surface‑mounted, suspended or spaced away from supporting surfaces using fixing devices, including special requirements for PT systems mounted at skirting (near‑floor) level.

Key topics and technical requirements

• Scope and classification
  • Defines wall PT systems, ceiling PT systems, and skirting PT systems and classifies systems by external‑load capability and provision for suspended loads.
• Mechanical strength and external load testing
  • Adds specific requirements and tests for external loads, suspension means and mechanical robustness (see Clause 14 additions such as subclause 14.3.101).
• Short‑circuit and electrical tests
  • Clauses 18–22 adapted to IEC 61534‑1:2011 and include short‑circuit test requirements and short‑circuit withstand strength.
• Marking and documentation
  • Mandates additional markings for systems that support loads (e.g., maximum load in kg for wall/ceiling systems and suspended loads).
• Safety and performance clauses
  • Addresses clearances, creepage, insulation, protection against electric shock, terminals, screw and connection requirements, temperature rise, insulation resistance and dielectric strength, fire hazard, external influences and EMC.
• Testing samples
  • Specifies sample numbers for particular mechanical tests (added testing details in Clause 5.3).

Practical applications and users

EN 61534-21 is essential for:

• Manufacturers of powertrack/track‑rail systems designing products for wall or ceiling mounting.
• Product designers and R&D teams assessing mechanical and electrical safety for mounted PT systems and luminaires.
• Test laboratories and certification bodies performing conformity testing (mechanical strength, short‑circuit, dielectric, temperature rise, EMC).
• Electrical installers, lighting designers and building services engineers specifying suitable PT systems for commercial, retail, office and industrial installations-especially where suspended luminaires or skirting‑level installations are used.
• Safety assessors and compliance managers ensuring products meet LVD and national adoption requirements.

Related standards

• IEC/EN 61534-1:2011 (+ AMD1:2014) - Part 1: General requirements (to be read together with Part 21).
• Other parts of the IEC 61534 series covering powertrack systems.

EN 61534-21:2014 provides the focused, application‑specific rules needed to ensure safe, reliable wall and ceiling mounted powertrack installations and to demonstrate compliance during design, testing and market entry.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
