Overview - EN IEC 62561-7:2018 (Earthing enhancing compounds)

EN IEC 62561-7:2018 (IEC 62561-7:2018) is the IEC/CENELEC standard that defines requirements and test methods for earthing enhancing compounds used in lightning protection system components (LPSC). This second edition (2018) supersedes the 2011 edition and constitutes a technical revision. It focuses on compounds that help produce low resistance of an earth termination system, and adds clarification for resistivity testing plus Annex A for assessing corrosion load.

Key topics and technical requirements

• Scope and purpose: Requirements and tests specific to earthing enhancing compounds intended for use in lightning protection systems designed per IEC 62305.
• Material and documentation: Manufacturers must provide material descriptions, instructions and marking information for safe and correct installation.
• Electrical performance (resistivity): Procedures for determining the resistivity of the compound and passing criteria are specified; the 2018 edition includes additional guidance on executing resistivity tests.
• Corrosion assessment: Mandated corrosion tests and the addition of Annex A provide methods for assessment of corrosion load on metallic electrodes and conductors.
• Chemical safety and leaching: Leaching tests and sulphur determination requirements are included to evaluate environmental/chemical behaviour and compliance.
• Test suite and reporting: Defines leaching, sulphur, resistivity and corrosion test procedures, required test apparatus, passing criteria and the structure/content of the test report (including equipment and measured results).
• Marking and traceability: Requirements for labelling, product identification and documentation to support installation and conformity assessment.

Practical applications and who uses this standard

• Manufacturers of earthing enhancing compounds use EN IEC 62561-7:2018 to design products that meet recognized safety and performance criteria.
• Test laboratories and certification bodies apply the specified test methods and reporting formats to assess compliance.
• Lighting protection designers, electrical engineers and installers refer to the standard when specifying materials to achieve reliable low-resistance earth terminations.
• Asset owners, infrastructure and utility managers use compliant products and test reports to reduce lightning risk and ensure long-term system integrity.
• Spec writers and procurement teams include the standard in tender documents to require verified product performance.

Related standards

• IEC 62305 (series) - Lightning protection (application context)
• EN/ISO and ASTM referenced test methods used within the standard, e.g. ISO 4689-3, ISO 14869-1, EN 12457-2, EN 16192, ASTM G57, ASTM G59, ASTM G102
• EN IEC 62561 series (other LPSC parts), including EN 62561-2

Part 7: Requirements for earthing enhancing compounds

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 62561-7 has been prepared by IEC technical committee 81:
Lightning protection.
This second edition cancels and replaces the first edition, published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) information concerning the execution of the test for the determination of the resistivity in
5.4.3;
b) addition of Annex A for the assessment of the corrosion load.
