30、ldwide 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
31、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 sub
32、ject 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 d
33、etermined 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 Co
34、mmittees. 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 wh
35、ich 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 Public
36、ation 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 n
37、ot 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 techn
38、ical 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
39、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 subjec
40、t of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62561-4 has been prepared by IEC technical committee 81: Lightning protection. This second edition cancels and replaces the first edition, published in 2010. This edition c
41、onstitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: new detailed flow chart of the tests; in Annexes A and B, composite fasteners have been added. IEC 62561-4:2017 IEC 2017 5 The text of this International Standard
42、is based on the following documents: FDIS Report on voting 81/564/FDIS 81/567/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives
43、, Part 2. A list of all parts in the IEC 62561 series, published under the general title Lightning protection system components (LPSC), can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC we
44、bsite under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 IEC 62561-4:2017 IEC 2017 INTRODUCTION This part of IEC 62561 deals with the requirements and tests for lightning
45、protection system components (LPSC), specifically conductor fasteners used for the installation of a lightning protection system (LPS) designed and implemented according to IEC 62305 (all parts). IEC 62561-4:2017 IEC 2017 7 LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) Part 4: Requirements for condu
46、ctor fasteners 1 Scope This part of IEC 62561 deals with the requirements and tests for metallic and non-metallic conductor fasteners that are used to retain and support the air-termination, down-conductor and earth-termination systems. This document does not cover the fixing of conductor fasteners
47、to the fabric of structures due to the vast number and types used in modern day construction. LPSC can also be suitable for use in hazardous atmospheres. There are therefore additional requirements when installing the components in such conditions. 2 Normative references The following documents are
