—   raccordements des câbles électriques.
Il spécifie également les calculs de largeur des plateaux de tampons.
Sauf indication contraire, toutes les dimensions figurant dans le présent document sont des valeurs nominales.

Železniške naprave - Vozna sredstva - Postavitev glavnega parka

Ta evropski standard se uporablja za vozila, opremljena z odbojniki in sistemi vijačnih spenjač.
Da bi omogočili delovanje in spenjanje vlakovnih kompozicij ali vozil, ta evropski standard določa zahtevani razmik za preklopnik, imenovan »bernski pravokotnik«, in potreben razmik za namestitev vlečne spenjače.
Ta evropski standard določa lokacijo, pritrditev in potreben razmik naslednjih elementov glavnega parka:
–   odbojnikov;
–   sistemov vijačnih spenjač;
–   zapornih pip;
–   pnevmatskih polspenjač;
–   priključkov za električne kable.
Določa tudi izračun širine glav odbojnikov.
Če ni drugače navedeno, so vse dimenzije, navedene v tem evropskem standardu, nominalne vrednosti.
