29、-4 Ed. 1.0 IEC - 4 - 81/313/CD 1 Scope This International 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 st
30、ructures 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. 2 Normative ref

35、th 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 N
36、on-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) Licensed Copy: London South Bank University, South Bank University, 02/02/2009 05:

38、ll 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
39、 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
40、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 manufacturers declaration for the classification of the fastener in accordance with Clause 4 and by test according to 6.
41、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 manufacturers 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
42、 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 follo
43、wing the manufacturers 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
44、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 IEC 62305-3. Compliance is
45、 checked by inspection in accordance with 6.5. 5.5 Marking Each conductor fastener shall be marked with: the manufacturers or responsible vendors name or logo or trademark; product identification or type; Licensed Copy: London South Bank University, South Bank University, 02/02/2009 05:37, Uncontrol

NOTE Marking may be applied for example by moulding, pressing, engraving, printing adhesive labels or water slide transfers.
47、 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 manufacturi
48、ng 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 manufactu
49、rer 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 manufacturers or suppliers 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
