Part 2:Dimensions, test methods and requirements for aluminium conductor cables
Véhicules routiers — Cables monoconducteurs de 60 V et 600 V — Partie 2: Méth odes d’essai des dimensions et exigences pour les cables conducteurs en aluminium.
4.3 Conductors
The conductors shall consist of annealed or annealed compressed/compacted aluminium, aluminium alloy, or copper-cladded aluminium strands. The specifications for the conductors shall be according to Iabkl and shall be completed by material specifications. Elongation requirements shall be established by the agreement between the customer and the supplier. The finished cable shall meet the resistance requirements of Table 5 for all conductors.
The individual strands of the aluminium conductor shall be manufactured per 1 000 series aluminium, pursuant to EN 573-1. The chemical composition shall follow EN 573-3:2009, Table 1.
NOTE Examples of strandings are shown in Tabh A.1. These strandings highlight examples of conceptual configurations and are not intended to reflect any preferred constructions. Other stranding configurations may be used provided they meet the requirements specified and are agreed upon by the customer and the supplier.
4.4 Tests
The cables shall be submitted to tests as specified in Table 3.
Unintended direct contact of aluminium wire with any other metal shall not occur with any of the test
methods.
4.5 General test conditions
If not otherwise specified, the device under test (DUT) shall be preconditioned for at least 16 h at a room temperature (RT) of (23 ± 5) °C and a relative humidity (RH) of 45 % to 75 %. Unless otherwise specified, all tests other than “in-process tests shall be conducted at these conditions.
Where no tolerance Is specified, all values shall be considered to be approximate.
When a.c. tests are performed, these shall be carried out at 50 Hz or 60 Hz. Applications at higher
frequencies may require additional testing.
4.6 Ovens
An oven with air exchange, either natural or by pressure, should be used. The air shall enter the oven in such a way that it flows over the surface of the test pieces and leaves near the top of the oven. The oven shall have not less than 8 and not more than 20 complete air changes per hour at the specified ageing temperature.
Forced air circulation, e.g. by a fan, inside the oven may be used. However, in case of dispute, an oven without forced air circulation shall be used.ISO 6722-2-2013 pdf free download.
