Electric cables - Calculation of the current rating - Part 2-3: Thermal resistance - Cables installe...
IEC 60287-2-3:2024 describes a method for calculating the continuous current rating factor for cables of all voltages installed in ventilated tunnels. The method is applicable to any type of cable. The method applies to natural as well as forced ventilation. Longitudinal heat transfer within the cables and the surroundings of the tunnel is assumed to be negligible. All cables are assumed to be…

Optical fibres - Part 1-22: Measurement methods and test procedures - Length measurement
IEC 60793-1-22:2024 establishes uniform requirements for measuring the length and elongation of optical fibre (typically within cable). The length of an optical fibre is a fundamental value for the evaluation of transmission characteristics such as losses and bandwidths.
Fibres optiques - Partie 1-22: Méthodes de mesure et procédures d'essai - Mesure de la longueur
L’IEC 60793-1-22:2024 établit des exigences uniformes pour mesurer la longueur et l’allongement de la fibre optique (typiquement dans le câble). La longueur d’une fibre optique est une valeur fondamentale pour l’évaluation des caractéristiques de transmission, telles que les pertes et la bande passante.
