Railway applications - Railway rolling stock - Draw gear and screw coupling

This standard specifies the requirement of the draw gear and screw coupling for the end rolling stock that have to couple with other interoperable rolling stock (freight wagons, locomotives, passenger vehicles ...).
This standard covers the functionality, construction, interfaces and testing including pass/fail criteria for draw gear and screw coupling.
The standard describes three categories of classification of draw gear and screw coupling, (1 MN, 1,2 MN and 1,5 MN).

Bahnanwendungen - Schienenfahrzeuge - Zugeinrichtung und Schraubenkupplung

Diese Norm umfasst die Funktionalität, Bauweise, Schnittstellen und Prüfungen einschließlich der Abnahme-kriterien für Zugeinrichtungen und Schraubenkupplungen.
In dieser Norm sind drei Kategorien von Zugeinrichtungen und Schraubenkupplungen beschrieben (1 MN, 1,2 MN und 1,5 MN).

Applications ferroviaires - Matériel roulant ferroviaire - Organes de traction et tendeur d'attelage

La présente norme spécifie les exigences relatives aux organes de traction et tendeurs d'attelage pour un matériel roulant devant être couplé à un autre matériel roulant interopérable (wagons de marchandises, locomotives, voitures, etc.).
La présente norme couvre la fonctionnalité, la construction, les interfaces et les essais, y compris les critères de réussite/d'échec aux essais pour les organes de traction et les tendeurs d'attelage.
La norme décrit trois catégories pour les organes de traction et les tendeurs d'attelage (1 MN, 1,2 MN et 1,5 MN).

Železniške naprave - Železniška vozila - Vlečna naprava in vijačna spenjača

Ta standard določa zahtevo za vlečno napravo in vijačno spenjačo končnega vozila, ki se mora speti z drugimi interoperabilnimi vozili (tovorni vagoni, lokomotive, potniška vozila, ...).
Ta standard zajema funkcionalnost, sestavo, vmesnike in preskušanje, vključno z merili za uspešno/neuspešno opravljen preskus, za vlečno napravo in vijačno spenjačo.
Standard opisuje tri razvrstitvene kategorije vlečne naprave in vijačne spenjače (1 MN, 1,2 MN in 1,5 MN).

European foreword

This document (EN 15566:2016) has been prepared by Technical Committee CEN/TC 256 “Railway

applications”, the secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall

be withdrawn at the latest by March 2017.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 15566:2009+A1:2010.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive 2008/57/EC.

For relationship with EU Directive 2008/57/EC, see informative Annex ZA, which is an integral part of

this document.
Modifications
Compared with EN 15566:2009+A1:2010 the following main changes have been done:
a) checking and revision of Clause 2 – Normative references;

b) modification in Clause 3 – working capacity (3.8) was deleted and intermediate coupling system for

permanent coupled wagons now defined as permanent coupling system;

c) in Clause 4, requirements for compressive loads for draw hook and draw gear rationalised and

explained;
d) in Clause 7,
...
