Alle Maße in diesem Dokument werden in Millimetern (mm) angegeben.
Es ist notwendig, die durchzuführenden Maßnahmen zum Einhalten der definierten Grenzwerte für Radsätze in einem besonderen Dokument zu beschreiben.
ANMERKUNG   Die Werte und besonderen Kriterien sind im entsprechenden Instandhaltungsplan festgelegt.

Applications ferroviaires - Exploitation des essieux en service - Maintenance des essieux en exploitation ou déposés

Pour assurer la sécurité et l’interopérabilité des circulations, la présente Norme Européenne donne
-  les valeurs limites pour les essieux posés sous véhicule et pour les essieux déposés,
-  les opérations à réaliser pour lesquelles les valeurs (et/ou critère) spécifiques restent à fixer dans la trame de maintenance.
La présente Norme Européenne s’applique aux essieux montés conformes aux Normes Européennes suivantes:

La présente Norme Européenne s’applique également aux essieux
-  éventuellement équipés de disques de frein, d’un pont moteur, d’une transmission ou de dispositifs d’insonorisation,
-  non conformes aux normes européennes reprises ci-dessus mais conformes aux prescriptions internationales en vigueur avant l’approbation de ces normes,
-  avec des roues bandagées,
-  avec des roues résilientes.
Pour le trafic intérieur et le trafic bilatéral, la présente Norme Européenne peut être utilisée, tout en sachant que des valeurs différentes peuvent être utilisées.
Toutes les dimensions de la présente Norme Européenne sont exprimées en millimètres (mm).
NOTE   Les prescriptions à respecter pour les composants autres que axes, roues, boîtes, roulements et graisse (disque de frein, pont moteur, transmission, dispositifs d’insonorisation, ...) doivent être définies dans un document spécifique.

Železniške naprave - Zahteve za kolesne dvojice med vožnjo - Vzdrževanje kolesnih dvojic v vgrajenem in razstavljenem stanju

Za zagotavljanje varnosti in medsebojne uporabnosti ta evropski standard določa:
omejitve za kolesne dvojice v vgrajenem in razstavljenem stanju;
potrebne postopke, za katere je treba v načrtu vzdrževanja definirati specifične vrednosti (in/ali kriterije).
Ta evropski standard se uporablja za kolesne dvojice, ki so v skladu z naslednjimi evropskimi standardi:
 EN 12080, EN 12081, EN 12082;
 EN 13103, EN 13104;
 EN 13260, EN 13261, EN 13262;

 EN 13715,
kar zajema:
os s premerom kolesa, večjim ali enakim 330 mm;
pestnice z ležaji in mastjo.
Ta evropski standard se uporablja tudi za kolesne dvojice:
opremljene z zavornimi diski, končno prestavo, menjalnikom ali sistemi za dušenje hrupa, kot je ustrezno;
ki niso skladne z zgoraj navedenimi evropskimi standardi, vendar so v skladu z mednarodnimi zahtevami, ki so bile v veljavi pred odobritvijo teh standardov;
s kolesi s pnevmatiko;
z odpornimi kolesi.
Standard se lahko uporablja za dvostranski in notranji promet, pri čemer se lahko vrednosti razlikujejo.
Vse dimenzije v tem evropskem standardu so podane v milimetrih (mm).
OPOMBA: zahteve, ki jih morajo izpolnjevati drugi sestavni deli, razen osi, koles, pestnic, ležajev in masti (npr. zavorni disk, končna prestava, menjalnik, sistem za dušenje hrupa itd.), je treba določiti v posebnem dokumentu.
