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

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

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
