However, for the purpose of this document, conductors may be selected from any national table. Conductors deviating in design from the standard values shall be given by the manufacturer, but fulilling all requirements given in EN 50182. Information about conductors made from profiled wires shall be provided by the manufacturer. Non-compacted conductors shall comply with EN 50182 or EN 62219 (with the exception of the flling, if any). For compacted conductors, based on conductors according to EN 50182, the following paragraph applies: The outer diameter of the compacted conductor shall be 95 % (+1 % for 7 and 19-wire constructions,士1,5 % for 37-wire constructions) of the diameter given in EN 50182. The rated tensile strength (RTS) shall be at least 95 % of the value given in EN 50182. The DC resistance shall not exceed the value given in EN 50182 by more than 5 %. BS EN 50397-1 pdf download.
