2 It is not applicable to cable infrastructure cables.
3 It rules:
4 The placing on the market of cables and cable end ties on the installations governed by the new right is subject to the LICa and the OICa.
5 It does not justify any additional or different requirements if there is an EC certificate of conformity and an EC declaration of conformity for the placing on the market of cables and cable-ends of cables forming part of subsystems and Security components.
1 A cable transportation facility that has been approved in accordance with the provisions of the LICa shall be considered to be governed by the new right 1 .
2 The former right shall be considered to be a cable transport facility whose operation has been authorised in accordance with the provisions valid before the entry into force of the LICa. These facilities may also include items that have been approved in accordance with the provisions of the LICa.
In order to derogate from this order, it is necessary to demonstrate through an analysis of the risks that the exemption does not increase the overall risk.
The cables of installations governed by the former right shall comply with the requirements of the rules of the art defined in the standards referred to in Annex 1 if this order does not provide for any other provisions.

1 The necessary safety factor and load assumptions for cables and cable end ties are defined:
2 Safety must be certified for the effective breaking force.
3 The minimum breaking strength indicated by the manufacturer is decisive as long as the effective tensile strength of the cables is not known.
4 For voltage cables for which the minimum breaking strength is greater than 4500 kN or with a diameter greater than 75 mm, the calculation of the safety justification may relate to the minimum breaking strength, taking into account a Cabling factor of 0.85. In addition, the evidence must be established that the total breaking strength is greater than the calculated break force.
5 In the calculation of the minimum breaking strength, the cable core is considered non-resistant.
