Lightning Protection System Components (LPSC) - Part 1: Requirements for connection components

NEW!IEC 62561-1:2017 is available as IEC 62561-1:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62561-1:2017 specifies the requirements and tests for metallic connection components that form part of a lightning protection system (LPS). Typically, these can be connectors, clamps, bonding and bridging components, expansion pieces and test joints. For the purposes of this document the following connection types are considered as connection components: exothermic, brazing, welding, clamping, crimping, seaming, screwing or bolting. Testing of components for an explosive atmosphere is not covered by this document. This second edition cancels and replaces the first edition, published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. classification of connection components in permanent and non-permanent connection; b. requirements and corresponding tests for permanent connection components such as exothermic, brazing, welding, crimping, seaming; c. flow chart of tests for connection components.

Overview

EN 62561-1:2017 (CLC adoption of IEC 62561-1:2017) specifies requirements and tests for metallic connection components used in lightning protection systems (LPS). This second edition (superseding EN 62561-1:2012) is a technical revision that clarifies classification and adds tests and requirements for permanent connections and an overall flow chart of tests. Typical components covered include connectors, clamps, bonding and bridging components, expansion pieces and test joints. The document excludes testing of components intended for explosive atmospheres.

Key topics and requirements

• Scope and classification
  • Components are classified by mechanical behaviour, installation location, ability to withstand lightning current and by whether a connection is permanent or non‑permanent.
• Connection types covered
  • Exothermic, brazing, welding, clamping, crimping, seaming, screwing and bolting.
• Electrical and mechanical requirements
  • Lightning current carrying capability and static mechanical stress requirements for connection components.
• Permanent vs non‑permanent connections
  • New requirements and tests for permanent connection methods (exothermic, brazing, welding, crimping, seaming).
• Testing framework
  • Detailed test procedures including specimen preparation, conditioning/ageing (salt mist, humid sulphurous, ammonia atmospheres where applicable), electrical tests, static mechanical tests and marking tests.
  • Includes a flow chart of tests and normative annexes summarizing requirements and test sequences.
• Documentation and marking
  • Installation instructions, marking and content/structure of test reports are specified to ensure traceability and consistent conformity assessment.
• Additional aspects
  • Electromagnetic compatibility (EMC) considerations are addressed; damage to conductors/metal installations and dismantling of test joints are covered.

Applications and who uses this standard

• Designers and engineers of lightning protection systems (LPS) who specify connection components for roofs, masts, earthing and bonding systems.
• Manufacturers and test laboratories developing or verifying connectors, clamps, bonding bars, expansion pieces and test joints for LPS.
• Installers and certification/inspection bodies requiring clear acceptance criteria, test methods and marking for compliant components.
• Asset owners and facility managers specifying components to meet IEC/CENELEC harmonized practices for lightning protection.

Related standards

• EN/IEC 62305 series (risk management and design of lightning protection systems) - referenced for overall LPS design context.
• EN 62561 (series) - other parts cover conductors, earth electrodes and additional LPSC elements.

Keywords: EN 62561-1:2017, lightning protection, connection components, LPS, connectors, clamps, bonding bar, exothermic, crimping, welding, lightning protection system components.

Part 1: Requirements for connection components

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.
International Standard IEC 62561-1 has been prepared by IEC technical committee 81:
Lightning protection.
This second edition cancels and replaces the first edition, published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) classification of connection components in permanent and non-permanent connection;
b) requirements and corresponding tests for permanent connection components such as
exothermic, brazing, welding, crimping, seaming;
c) flow chart of tests for connection components.
