1 Scope
This European standard specifies requirements and tests for:
− metallic and non-metallic conductor fasteners that are used in conjunction with the air termination system
and down conductors;
− fixing of fasteners to the fabric / membrane / gravel roofing of structures is not covered by this standard
due to the vast number and types used in modern day construction.
LPC may also be suitable for use in hazardous atmospheres. Regard should then be taken of the extra
requirements necessary for the components to be installed in such conditions.

3 Definitions
For the purpose of this European Standard, the following definitions apply.
3.1
conductor fastener
a metallic, non-metallic or composite component designed to retain and support the air termination and down
conductor, installed at intervals along the length of the conductors
NOTE The conductor fastener may be provided with a means of attachment to a mounting surface.
4 Classification
Conductor fasteners are classified:
4.1 According to the material composition
4.1.1 Metallic (e.g. hot dip galvanized steel, copper, aluminium, stainless steel)
4.1.2 Non-metallic (e.g. PVC, plastics)
4.1.3 Composite (combination of metal and plastic)
4.2 According to fixing arrangement of the conductor within the fastener
4.2.1 With screws
4.2.2 Without screws (e.g. clips, springs)

4.3 According to conductor clamping arrangement
4.3.1 Fasteners that are designed to clamp the conductor
4.3.2 Fasteners that are designed to allow axial movement of the conductor
5 Requirements
5.1 General
The conductor fastener shall carry out its function of clamping the conductor in an acceptable and safe
manner when subjected to mechanical influences, lightning discharge stress and environmental influences.
Conductor fasteners shall be so designed and constructed that safe handling is ensured and that retention
and support for the conductor is provided and that in normal use their performance is reliable and without
danger to persons and the surrounding.
The material of the conductor fastener shall be compatible with the conductor it is fastening, and the surface
material it is fastening on and comply with the tests given in Clause 6.
5.2 Environmental requirements
5.2.1 Corrosion resistance
Metallic or composite fasteners shall withstand corrosion effects.
Compliance is checked following the manufacturer’s declaration for the classification of the fastener in
accordance with Clause 4 and by test according to 6.3.1 and 6.3.3.
5.2.2 UV resistance
Non-metallic and composite fasteners shall withstand UV effects.
Compliance is checked following the manufacturer’s declaration for the classification of the fastener in
accordance with Clause 4 and by test according to 6.3.2 and 6.3.3.
5.3 Mechanical strength
5.3.1 Perpendicular and axial loads
The design of the conductor fastener shall be such that it carries the perpendicular loads caused by the
weight of the conductor, snow, ice and wind and axial loads caused by the thermal expansion / contraction of
the conductor and its weight.
Compliance is checked following the manufacturer’s declaration for the classification of the fastener in
accordance with Clause 4 and by test according to 6.4.1 and 6.4.2.
5.3.2 Impact tests
Conductor fasteners shall be so designed and constructed to withstand impact stresses caused accidentally.
Compliance is checked by test according to 6.4.3.
5.4 Installation instructions
The manufacturer or supplier of the conductor fastener shall provide adequate information in his literature to
ensure that the installer can select and install the component in a suitable and safe manner, in accordance
with EN 62305-3.
Compliance is checked by inspection in accordance with 6.5.

EN 50164-4:2008 - 6 -
5.5 Marking
Each conductor fastener shall be marked with:
− the manufacturer’s or responsible vendor’s name or logo or trademark;
− the product identification or type.
Where it is not possible to make these marks directly onto the product, they shall be on the smallest supplied
packaging.
NOTE  Marking may be applied for example by moulding, pressing, engraving, printing adhesive labels or water slide transfers.
Compliance is checked in accordance with 6.6.
6 Tests
6.1 General test conditions
Tests according to this standard are type tests. 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.
The standard cannot cover all possible types of fasteners and the way of fixing them on various surfaces of
different materials. When required, for these applications, agreement should be obtained between the test
engineer and manufacturer on the specific testing regime.
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, with the recommended conductor materials,
sizes and the tightening torques.
The tests shall be carried out in the sequence given after environmental tests of the specimen in accordance
with 6.3.
Unless otherwise specified, twelve metallic or eighteen composite / non metallic 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 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 made in the same required sequence on another full set of samples, all of which shall comply with the
requirements.
Tests for non-metallic fasteners shall not commence earlier than 168 h from the time of their manufacturing.
Unless otherwise specified, the tests shall be carried out in a room whose ambient temperature ranges
between +15 °C and +40 °C.
Unless otherwise specified, the tests shall be carried out in a room whose relative humidity ranges between
25 % and 75 %.
A torque meter shall be used for all tightening operations. It shall have a resolution at least of 0,5 Nm and an
accuracy not above ± 4 %.
The applicable tolerance for any applied mechanical load shall be within ± 5 %.
NOTE  The applicant, when submitting the first set of samples may also submit an additional set of samples that may be necessary
should one sample fail. The test house shall then, without further request, test the additional set of samples, and shall only reject if a
further failure occurs. If the additional set of samples is not submitted at the same time, a failure of one sample shall entail rejection.
6.2 Test preparation
6.2.1 Arrangement of the specimen
If not otherwise specified by the manufacturer the conductors and specimens shall be cleaned by using a
suitable degreasing agent followed by cleaning in demineralised water and drying. They shall then be
assembled in accordance with the manufacturer’s installation instructions, e.g. with the recommended
conductors and the tightening torques.
