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.

NOTE The parameters specified in Table 1 can typically be achieved by an exponentially decaying lightning
impulse current having a time to half value 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) is of stainless steel, a value of 3 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 a non-permanent connection component, in accordance with 4.4 b), utilizing screws,
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) for a non-permanent connection component, in accordance with 4.4 b), 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;
e) for screw-less or permanent connection components, in accordance with 4.4 a), 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 connection component or conductor.

tested on the minimum conductor size recommended. If the connection range is greater than
2 mm it shall be tested on the minimum and maximum size of conductor recommended.
6.5.2 Test procedure
A second set of 3 new connection components 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.
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 to the connection component or
conductor.
6.6 Marking test
The marking is checked by inspection and by rubbing it by hand for 15 s with a piece of cloth
soaked with water and again for 15 s with a piece of cloth soaked with white spirit/mineral
spirit.
Markings made by moulding, pressing or engraving are not subjected to this test.
The specimen is deemed to have passed the test if the marking remains legible.
