6 Tests
6.1 General conditions for tests
The tests in accordance with this standard are type tests.
• 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 installation
instructions with the recommended conductor materials, sizes and tightening torques. If
the connection component is suitable for various conductors’ materials, then it shall be
tested on each material combination.
• All tests are carried out on new specimens.
• Unless otherwise specified, three specimens are subjected to the tests and the
requirements are satisfied if all the tests are met.
• 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. The tests which follow shall also be carried out in the required
sequence on another full set of specimens, all of which shall comply with the
requirements.
• The electrical test shall be carried out in the order given after conditioning/ageing of the
arrangement of the specimen in accordance with 6.2.2.
The applicant, when submitting the sets of specimens, may also submit an additional set of
specimens which may be necessary should one specimen fail. The testing station will then,
without further request, test the additional set of specimens and will reject 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.
6.2 Test preparation
6.2.1 Arrangement of the specimen
If not otherwise specified by the manufacturer, the conductors and the specimens shall be
cleaned by using a suitable degreasing agent followed by cleaning in demineralizing water
and drying. They shall then be assembled in accordance with the manufacturer’s instructions,
e.g. with the recommended conductors and tightening torques.
The connection component shall be tested in all the connection configurations declared by the
manufacturer in Annex B.
Any connection components accommodating a range of conductors with a variation on any
dimension equal to or less than 2 mm shall be tested using the minimum conductor size
recommended. If the range of conductor sizes is greater than 2 mm, it shall be tested using
the minimum and maximum size of conductors recommended.
The basic arrangement of the specimen with cross connection component, parallel connection
component, bridging component and equipotential bonding bar is shown in Figures 1, 2, 3 and
4, respectively. Terminals of bonding bars are only tested if the connection size is equal to or
greater than 16 mm . The test is carried out using the smallest conductor size within the
range of the terminal with a minimum of 16 mm conductor. Typical arrangements for various
LPSCs are shown in Annex B.
6.2.2 Conditioning/ageing
Following the manufacturer’s declaration for the location of the connection components in
accordance with 4.2, the arrangement of the specimen shall be subjected to a
conditioning/ageing, as per Annex C, consisting of a salt mist treatment as specified in C.1
followed by a humid sulphurous atmosphere treatment as specified in C.2, and an additional
ammonia atmosphere treatment for specimens made of copper alloy with copper content less
than 80 % as specified in C.3.
After the treatment, the arrangement is fixed on an insulated plate, taking care to avoid any
damage to the specimen due to handling.
This treatment is not necessary for connection components designed to be completely
embedded in concrete. Connection components designed to be partially embedded in
concrete shall be subjected to the conditioning/ageing as per this clause.
Bonding bars destined for indoor applications only are tested without conditioning/ageing.
6.3 Electrical test
After 6.2.2 and without cleaning the arrangement, the specimen shall be stressed three times
by a test current as given in Table 1. The time interval between individual shots shall allow
the arrangement of the specimen to cool down to approximately ambient temperature.
The impulse discharge current passing through the device under test is defined by the crest
value I , and the specific energy W/R The impulse current shall show no reversal and reach
imp .
I within 50 µs. The transfer of the specific energy W/R shall be dissipated within 5 ms.

NOTE The parameters specified in Table 1 can typically be achieved by
an exponential decaying current in the range of 350 μs according to
IEC 62305-1.
The connection component is deemed to have passed the test if:
a) the contact resistance, measured with a source of at least 10 A as close as possible to the
connection component is equal to or less than 1 mΩ. In the case where the connection
component or the conductor(s) are of stainless steel, a value of 2,5 mΩ is allowed;
b) it does not exhibit any crack to normal or corrected vision without magnification nor does it
have any loose parts or deformation impairing its normal use;
c) for screwed clamping connections the loosening torque is greater than 0,25 and less than
1,5 times the tightening torque. In the case of connectors with more than one screw, only
the loosening torque of the first screw is relevant to this test;
d) the 20 mm length of conductor from the connector (see Figures 1, 2 and 4), prior to the
test is not less than 3 mm after completion of the test. For examples B3, B4, B6 and B8 as
shown in Annex B, the requirement of not less than 3 mm is not applicable;
e) the measurement of the contact resistance of the expansion components (E) and the
connected conductors (F) is performed between the clamped ends A-B and C-D, as close
as possible to the expansion component (see Figure 5);
f) the expansion conductor (E, see Figure 5) shall be tested according to IEC 62561-2 and
shall fulfill the requirements for air termination conductors;
g) for screw-less components, such as compressed connection components, each conductor
of the specimen assemblies shall be subjected independently to a mechanical tensile force
of 900 N ± 20 N, for 1 min. Each conductor shall be tested independently for multiple
conductor connectors. The connection component is deemed to have passed the test if
there is less than 1 mm movement of the conductor during the test and no damage on the
connector or conductor.
6.4 Static mechanical test
A second set of three new specimens shall be arranged according to the manufacturer’s or
supplier’s installation instructions with the recommended conductor materials, sizes and
tightening torques.
Each conductor of the specimen assemblies shall be subjected independently to a mechanical
tensile force of 900 N ± 20 N for 1 min. Each conductor shall be tested independently for
multiple conductor connectors.
The connection component is deemed to have passed the test if there is less than 1 mm
movement of the conductor during the test and no damage on the connector or conductor.
