Overview

EN 62549:2011 (adopting IEC 62549:2011) defines requirements and tests for articulated systems and flexible systems for cable guiding used to accommodate and retain cables and, where applicable, other electrical equipment in electrical and communication installations. It applies to systems with adaptable linear geometry for cable guiding and covers installations up to 1 000 V a.c. and 1 500 V d.c. The standard explicitly excludes cable trunking, conduit, tray, ladder, powertrack and energy-chain systems that are covered by other standards.

Key topics and technical requirements

EN 62549:2011 addresses design, construction and testing elements essential to safe, reliable cable management systems:

• Scope & classification - application limits (voltage), temperature classes and impact-resistance categories.
• Marking and documentation - required product identification, instructions and technical data for safe installation.
• Dimensions and geometry - guidance on clearances and minimum bending radius for flexible/cabled runs.
• Construction requirements - avoidance of sharp edges, cable retention provisions, inlet openings and reliable apparatus mounting.
• Protection features - requirements for ingress protection (IP) and access to hazardous parts, plus electrical continuity and earthing for conductive parts.
• Mechanical tests - impact tests (IK), external load, axial load and compression tests to verify mechanical strength and durability.
• Electrical and fire performance - continuity checks and fire-hazard testing references (glow-wire, needle-flame methods) to mitigate ignition and flame propagation risks.
• External influences & EMC - degree of protection against foreign objects and water (IP code) and electromagnetic compatibility considerations.
• Normative references include IEC standards such as IEC 60068-2-75, IEC 60529 (IP), IEC 60670 series and IEC 60695 series.

Practical applications

EN 62549 is used to specify, design and verify articulated and flexible cable guiding systems in commercial, industrial and communication installations where adaptable routing is required (e.g., articulated arms, flexible conduits or cable guiding chains). It supports:

• Product design and manufacturing (component specification and validation)
• Type testing and certification by test labs
• Technical procurement and tender specifications
• Installation guidance for electrical contractors and system integrators

Who uses this standard

• Cable management system manufacturers and designers
• Electrical accessory and installation product engineers
• Test laboratories and conformity assessment bodies
• Specifiers, procurement teams and installation contractors
• Compliance officers ensuring adherence to European/CENELEC requirements

ARTICULATED SYSTEMS AND FLEXIBLE
SYSTEMS FOR CABLE GUIDING
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. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

If precautions are taken in order to prevent creepage distances and clearances from becoming less than 3 mm, even if a conductor should become loose from its terminal, the accessible conductive part is not considered likely to become live. Protection against electric shock in case of a fault may be omitted for accessible conductive parts which, owing to their reduced dimensions (up to approximately 50 mm x 50 mm) or their disposition, cannot be gripped or come into significant contact with a part of the human body and provided that connection with a protective conductor could only be made with difficulty or would be unreliable. NOTE This requirement applies, for example, to bolts, rivets, nameplates and cable clips. Compliance is checked by inspection, measurement and if necessary by the appropriate test of 11.1. 9.9.3 Accessible conductive parts need not have provision for connection to earth if they are insulated from live parts with supplementary or reinforced insulation used to form barriers or linings which shall be designed in such a way that – they cannot be removed without being permanently damaged or – they cannot be replaced in an incorrect position or – if omitted, the system is rendered inoperable or manifestly incomplete. Compliance is checked by inspection. NOTE For particular applications, it may be necessary to equipotentially bond these parts or to connect these parts to the earthing conductor for functional purposes such as EMC. 9.10 Electrically protective separation Under consideration. 9.11 Inlet openings Inlet openings, if any, shall allow the introduction of conduits and/or the like or the protective covering of the cable at least 1 mm into the system component in order to maintain the mechanical protection. Inlet openings for conduits shall be capable of accepting conduit sizes according to IEC 60423:2007. Compliance is checked by inspection and measurement. 9.12 Mechanical connections 9.12.1 Screwed connections and other mechanical connections shall withstand the mechanical stresses during installation and normal use.
