32、e air termination, down conductor and earth termination system, installed at intervals along the length of the conductors 4 Classification Conductor fasteners are classified as follows: a) According to material metallic (e.g. hot dip galvanized steel, copper, aluminium, stainless steel); non-metalli
33、c (e.g. PVC, plastics); composite (combination of metal and plastic); b) According to fixing arrangement of the conductor within the conductor fastener with screws; without screws (e.g. clips, springs); c) According to conductor clamping arrangement conductor fasteners that are designed to clamp the
34、 conductor; conductor fasteners that are designed to clamp but 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
35、 stress and environmental influences. Conductor fasteners shall comply with the tests given in Clause 6. The material of the conductor fastener shall be compatible with the conductor it is fastening and the surface material onto which it is mounted. NOTE 1 Certain extreme environmental conditions ma
36、ke the choice of non-metallic conductor fasteners unsuitable. Specific recommendations should be provided by manufacturers as to their suitability in varying environments. NOTE 2 Conductor fasteners should be so designed and constructed that safe handling is ensured, that retention and support for t
37、he conductor is provided, and that in normal use their performance is reliable and without danger to persons and the surrounding. 5.2 Environmental requirements 5.2.1 Corrosion resistance Metallic or composite conductor fasteners shall withstand corrosion effects. Compliance is checked following the
38、 manufacturers declaration for the classification of the conductor fastener in accordance with Clause 4 and by test specified in 6.3.2 and 6.3.4. 5.2.2 UV resistance Non-metallic and composite conductor fasteners shall withstand UV effects. Compliance is checked following the manufacturers declarati
39、on for the classification of the conductor fastener in accordance with Clause 4 and by test specified in 6.3.3 and 6.3.4 BS EN 62561-4:2011 EN 62561-4:2011 (E) 7 5.3 Mechanical strength 5.3.1 Perpendicular and axial loads The design of the conductor fastener shall be such that it carries the perpend
40、icular loads caused by the weight of the conductor, snow, ice and wind and axial loads caused by the thermal expansioncontraction of the conductor and its weight. Compliance is checked following the manufacturers declaration for the classification of the conductor fastener in accordance with Clause
41、4 and by test specified in 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 specified in 6.4.3. 5.4 Installation instructions The manufacturer or supplier of the conductor fast
42、ener 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 . Compliance is checked by inspection in accordance with 6.5. 5.5 Marking Each conductor fastener shall be marked with the man
43、ufacturers or responsible vendors name or logo or trademark, product identification or type. Where it is not possible to make these marks directly onto the product, they shall be made on the smallest supplied packaging. NOTE Marking may be applied for example by moulding, pressing, engraving, printi
44、ng adhesive labels or water slide transfers. Compliance is checked in accordance with 6.6. 6 Tests 6.1 General test conditions Tests specified in 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
45、the materials, design or type of manufacturing process, which might change the performance characteristics. The standard cannot cover all possible types of conductor fasteners and the way of fixing them on various surfaces of different materials. When required, for these applications, agreement shou
46、ld 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 specified in the manufacturers or suppliers instructions, with the recommended conductor materials,
47、sizes and the tightening torques. EN 62305 -3 BS EN 62561-4:2011 EN 62561-4:2011 (E) 8 The tests shall be carried out in the sequence given after environmental tests of the specimen in accordance with 6.3. Unless otherwise specified, 12 metallic or 18 composite/non metallic specimens are subjected t
48、o the tests and the requirements are satisfied if all the tests are met. If only one of the specimens fails to 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 mad
49、e in the same required sequence on another full set of samples, all of which shall comply with the requirements. Tests for non-metallic conductor fasteners shall not commence earlier than 168 h from the time of their manufacturing. A torque meter shall be used for all tightening operations. It shall have a resolution of at least 0,5 Nm and an accuracy of 4 % or less. The applicable tolerance for any applied mechanical load shall be within 5 %. NOTE The a
