INTRODUCTION
This part of IEC 62561 deals with the requirements and tests for lightning protection system
components (LPSC), specifically isolating spark gaps (ISG) 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 (ISG)

1 Scope
This part of IEC 62561 specifies the requirements and tests for isolating spark gaps (ISG) 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 electrode 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.

6 Tests
6.1 General conditions for tests
The tests in accordance with this document are type tests and performed in a sequence
according to Annex A.
These tests are of such a nature that, after they have been performed, they need not be
repeated unless changes are made to the materials, design or type of manufacturing process,
which might change the performance characteristics of the product.
a) Unless otherwise specified, tests are carried out with the specimens assembled and
installed as in normal use according to the manufacturer's or supplier's instructions.
b) Unless otherwise specified, three specimens are subjected to the tests and the
requirements are satisfied if all the tests are met.
c) If only one of the specimens does not satisfy a test due to an assembly or a manufacturing
fault, that test and any preceding one which may have influenced the results of the test
shall be repeated and also the tests which follow shall be carried out in the required
sequence on another full set of specimens, all of which shall comply with the
requirements.
d) If the ISG has an integral connection component part with its design, it shall be subjected
to the testing regime of IEC 62561-1 using the appropriate lightning current given in
Table 1 of this document.
The applicant, when submitting a set of specimens, may also submit an additional set of
specimens which may be necessary should one specimen fail. The testing laboratory will
then, without further request, test the additional set of specimens and will reject the sets only
if a further failure occurs. If the additional set of specimens is not submitted at the same time,
the failure of one specimen will entail rejection.
Prior to the testing of the ISG and clamp assembly, suitable protection measures should be
employed to ensure that the housing is not exposed to the conditioning treatment.

– 12 – IEC 62561-3:2017 © IEC 2017
6.2 UV (ultraviolet) light test
This test is necessary for ISGs designed to be installed outdoors or in specific environments.
ISG housings for outdoor application shall withstand UV light effects.
One set of three new specimens shall be assembled and mounted rigidly on an insulating
plate (e.g. brick, polytetrafluoroethylene (PTFE)) in accordance with the manufacturer’s
installation instructions.
The specimens shall be subjected to an environmental test consisting of an ultraviolet light
test as specified in Annex C.
The specimens are deemed to have passed this part of the test if there are no signs of
disintegration and no cracks visible to normal or corrected vision.
Ensure that the surface of the mounting plate is suitable to resist UV radiation.
6.3 Resistance tests to corrosion
This test is necessary for ISGs having metallic parts designed to be installed outdoors or in
specific environments.
The specimens used in and complying with the test in 6.2, shall be subjected to corrosion
tests as per Annex B.
After the parts have been dried during 10 min in a drying oven at a temperature of
100 ºC ± 5 ºC, they shall not present any trace of rust on surfaces.
Traces of rust on the edges or a yellowish stain removed by rubbing are not taken into
account. White rust, patina and other surface oxidations are not considered as corrosive
deterioration.
6.4 Mechanical tests
All specimens complying with 6.2 and 6.3 shall be stressed three times by mechanical
impacts.
The impacts are carried out on the accessible parts of the ISG, which may be mechanically
stressed accidentally.
The specimens are assembled under their normal operating conditions specified in the
manufacturer’s documentation.
The ISG is mounted on a pendulum hammer test apparatus according to
IEC 60068-2-75:1997, Clause 4, as shown in Figure 1. The striking element material shall be
polyamide as per IEC 60068-2-75:1997, Table 1, and its mass shall be 200 g as per

Figure 1 – Pendulum hammer test apparatus
The hammer shall fall from a height of 200 mm so that one impact on each side is applied, as
far as possible perpendicular to the length of the arrangement. The drop height is the vertical
distance between the position of the point of control, when the pendulum is released, and the
position of this point at the time of the impact.
The point of control is located on the surface of the striking part where the line passing
through the point of intersection of the axes of the steel tube of the pendulum and the part of
striking, perpendicular to the plane crossing the two axes, comes into contact with the
surface.
The impacts are not applied to the connectors.
NOTE In theory, the centre of gravity of the striking part should be the point of control. As, in practice, it is
difficult to determine the centre of gravity, the point of control has been chosen as described above.

– 14 – IEC 62561-3:2017 © IEC 2017
After the test, the ISG shall show no cracks or similar damage visible to normal or corrected
vision without magnification and shall not present damage which can potentially affect its later
use.
6.5 Electrical tests
6.5.1 Isolation resistance
The test is conducted with a DC voltage of 0,5 times the rated withstand voltage up to a
maximum of 500 V.
The resistance shall be measured after 30 s of applying the test voltage.
The specimen is deemed to have passed the test if the resistance is equal or greater than
500 kΩ.
6.5.2 Withstand voltage
6.5.2.1 General
The rated withstand voltages shall be tested according to the value declared by the
manufacturer in accordance with 5.3.
6.5.2.2 Power frequency withstand voltage
6.5.2.2.1 General conditions for tests
The rated power frequency withstand voltage is tested by applying an AC voltage at the
terminals of the ISG. The voltage is increased continuously at a rate of 100 V/s with a nominal
frequency of 50 Hz or 60 Hz until the r.m.s. value as declared by the manufacturer is reached
and this is maintained for a time of 60 s ± 1 s.
The prospective short-circuit current of the source may be limited to a minimum value of
5 mA.
6.5.2.2.2 Acceptance criteria
The specimens are deemed to have passed the test if during the application of the test
voltage the ISG does not spark over, or conduct a leakage current exceeding 1 mA.
6.5.2.3 DC withstand voltage
6.5.2.3.1 General conditions for tests
The rated DC withstand voltage shall be tested by applying a DC voltage at the terminals of
the ISG. The voltage shall be increased continuously at a rate of 100 V/s until the value as
declared by the manufacturer is reached and this is maintained for a time of 60 s ± 1 s.
The prospective short circuit current of the source may be limited to a minimum value of
5 mA.
6.5.2.3.2 Acceptance criteria
The specimens are deemed to have passed the test if during the application of the test
voltage the ISG does not spark over, or conduct a leakage current exceeding 1 mA.

6.5.3 Rated impulse sparkover voltage
6.5.3.1 General conditions for tests
An impulse voltage 1,2/50 μs with a peak value of the declared impulse sparkover voltage
shall be applied at the terminals of the ISG. The test is performed with five surges of positive
and negative polarity and the ISG has to spark over at each test impulse.
6.5.3.2 Acceptance criteria
The specimens are deemed to have passed the test if they have operated at each test
impulse and no signs of cracks or punctures appear on the enclosures.
6.5.4 Lightning current
6.5.4.1 General conditions for tests
After 6.5.3 and the conditioning according to Annex B, the specimens shall be pre-stressed
with a test current of 0,5 I , followed by a second test current of I after the ISG has
imp imp
cooled down close to ambient temperature.
The impulse discharge current passing through the device under test is defined by the crest
value I , the charge Q and the specific energy W/R. The impulse current shall show no
imp
reversal and reach I within 50 µs. The transfer of the charge Q shall occur within 5 ms and
imp
the specific energy W/R shall be dissipated within 5 ms.
All the parameters are given in Table 1.

The parameters are derived from the 3 edition of IEC 62305-1 which is under preparation.

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.

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 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 information specified in 8.2 to 8.9.
8.2 Report identification
The following information shall be included :
a) A title or subject of the report.
b) Name and email address or telephone number of the testing laboratory.
c) Name, address and telephone number of the sub-testing 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 and the total number of pages indicated on each page,
including appendices or annexes.
g) Date of issue of the report.
