Communication cables - Part 2-20: Common design rules and construction - General
EN 50290-2-NN contains, in its various parts, the requirements for polymeric insulating, sheathing and covering materials that are used for metallic and optical fibre cables (Table 1).
The materials to be used for EN standardised communication cables are not, and will not be, restricted only to those defined (Table 1). New materials for cables will be described in further parts of the series. The current structure of the EN 50290-2-NN series is outlined in Annex A.
Furthermore, the use of materials described in the EN 50290-2-NN series for other cable applications outside those defined (Table 1) is not prohibited, but it is strongly recommended that expert advice be taken before such use, or before any proposal for incorporation into another standard.

L'EN 50290-2-X contient, dans ses différentes parties, les exigences relatives à l'isolation, au gainage et aux matériaux de revêtement par polymères utilisés pour les câbles métalliques et les câbles à fibres optiques (voir Tableau 1).
Les matériaux à utiliser pour les câbles de communication normalisés EN ne sont et ne seront pas limités aux matériaux définis dans le Tableau 1. De nouveaux matériaux pour les câbles seront décrits dans d'autres parties de la série. La structure actuelle de la série EN 50290-2-NN est présentée dans l'Annexe A.
De plus, l'utilisation des matériaux décrits dans la série EN 50290-2-NN pour des applications de câbles différentes de celles définies dans le Tableau 1 n'est pas interdite, mais il est fortement recommandé d'avoir l'avis d'un expert avant une telle utilisation, ou avant toute proposition d'incorporation dans une autre norme.
Komunikacijski kabli - 2-20. del: Skupna pravila načtovanja in konstrukcija - Splošno
Standard EN 50290-2-NN v različnih delih vsebuje zahteve za polimerno izolacijo, oplaščenje in pokrivne materiale, ki se uporabljajo za kovinske kable in kable z optičnimi vlakni (preglednica 1).
Materiali, ki se uporabljajo za komunikacijske kable, standardizirane po EN, niso in ne bodo omejeni samo na tiste, ki so opredeljeni (preglednica 1). Novi materiali za kable bodo opisani v nadaljnjih delih skupine standardov. Trenutna struktura skupine standardov EN 50290-2-NN je navedena v dodatku A.
Poleg tega uporaba materialov, opisanih v skupini standardov EN 50290-2-NN, za druge vrste uporabe kablov zunaj tistih, ki so opredeljeni (preglednica 1), ni prepovedana, vendar se močno priporoča, da se pred takšno uporabo ali pred predlogom za vključitev v drug standard pridobi nasvet strokovnjaka.

For the purpose of the current document series, the polymer type is categorised as that of the largest component. Thus a PP/PE blend of ratio 60/40 would be classified as a PP polymer. 5 Maximum operating temperature The maximum operating temperature of telecommunication cables is based on thermal degradation, heat deformation characteristics and the thermal sensitivity of the dielectric properties. Most normal telecommunication cable applications define the maximum operating temperature as 60°C. This operating temperature can be a result of the external environment, conductor heating or a combination of both. The requirements and test methods may need to be reconsidered in the light of developing power over the Ethernet (POE) requirements. Unless stated otherwise all the materials described in EN 50288-2 are suitable for 70°C operating temperature. For certain applications (EN 50288-7) higher operating temperatures are necessary (eg. PP, XLPE at 90°C, SiR, FEP >90°C). For these products the focus is more on the potential for thermal degradation. Thermal degradation (ageing) performance can be demonstrated by techniques such as Arrhenius ageing (EN 60216) or by conventional heat ageing at elevated temperatures. Using the Arrhenius ageing protocol it is possible to predict the life expectancy (typically
