INTRODUCTION
This part of IEC 62561 deals with the requirements and tests for lightning protection system
components (LPSC), specifically isolating spark gaps (ISGs) used for the installation of a
lightning protection system (LPS) designed and implemented according to the IEC 62305
series.
LIGHTNING PROTECTION SYSTEM COMPONENTS (LPSC) –

Part 3: Requirements for isolating spark gaps (ISGs)

1 Scope
This part of IEC 62561 specifies the requirements and tests for isolating spark gaps (ISGs) for
lightning protection systems.
ISGs can be used to indirectly bond a lightning protection system to other nearby metalwork
where a direct bond is not permissible for functional reasons.
Typical applications include the connection to
• earth-termination systems of power installations,
• earth-termination systems of telecommunication systems,
• auxiliary earth electrodes of voltage-operated, earth fault circuit breakers,
• rail earth electrodes of power and DC railways,
• measuring earth electrodes for laboratories,
• installations with cathodic protection and stray current systems,
• service entry masts for low-voltage overhead cables,
• bypassing insulated flanges and insulated couplings of pipelines.
This does not cover applications where follow currents occur.
NOTE Lightning protection system components (LPSC) can also be suitable for use in hazardous conditions such
as fire and explosive atmosphere. Due regard will be taken of the extra requirements necessary for the components
to be installed in such conditions.
Applications where follow currents occur are not included.
Extra requirements for the components can be necessary for LSCs intended for use in
hazardous atmospheres.
NOTE 1 In CENELEC member countries, testing requirements of components for explosive atmospheres are
specified in CLC/TS 50703-2.
NOTE 2 Testing of components for an explosive atmosphere (as defined in the IEC 60079-10 series) is not covered
by this document.

NOTE When a lightning current flows in an arc, a shock wave is produced. The severity of the shock is dependent
upon the peak current and the rate of rise of the current. The shorter the rise time, the greater the severity. In general,
the acoustic shock wave can cause damage to the surrounding components, such as the enclosure of the ISG.

6.5.4.2 Acceptance criteria
The specimens are deemed to have passed the test if no signs of cracks or punctures appear
on the enclosures.

8 Structure and content of the test report
8.1 General
The purpose of this Clause 8 is to provide general requirements for laboratory test reports. It is
intended to promote clear, complete reporting procedures for laboratories submitting test
reports.
The results of each test carried out by the testing laboratory shall be reported accurately,
clearly, unambiguously and objectively, in accordance with any instructions in the test methods.

The results shall be reported in a test report and shall include all the information necessary for
the interpretation of the test results and all information required by the method used.
Particular care and attention shall be paid to the arrangement of the report, especially with
regard to presentation of the test data and ease of assimilation by the reader. The report shall
be arranged and presented in such a way that it is easily assimilated by the reader, especially
with regards to presentation of the test data. The format shall be carefully and specifically
designed for each type of test carried out, but the headings shall be standardized as indicated
below.
The structure of each report shall include at least the information specified given in 8.2 to 8.9.
8.2 Report identification
The following information shall be included in the report
a) a title or subject of the report;
b) name and email address or telephone number of the test laboratory;
c) name, address and telephone number of the sub-test laboratory where the test was carried
out if different from the company which has been assigned to perform the test;
d) unique identification number (or serial number) of the test report;
e) name and address of the vendor;
f) Report shall be paginated report and indication of the total number of pages indicated on
each page, including appendices or annexes;
