Railway applications - Measurement of vertical forces on wheels and wheelsets - Part 2: Test in workshop for new, modified and maintained vehicles

This document applies to the measurement of vertical wheel forces of railway vehicles in maintenance workshops and at manufacturing sites. It also deals with derived quantities that are used to describe the vehicle’s vertical wheel force distribution.
The document defines the assessment and acceptance criteria for the measurement process. The requirements for this assessment support the specification, the design and the operation of the measurement process. It is considered that the measurements are made either statically or quasi-statically. This document is applicable to all railway vehicles.
The commercial weighing of vehicles is not covered by the scope of this document, nor does it define in which cases the wheel forces of a vehicle will be measured.

Bahnanwendungen - Messung von vertikalen Rad- und Radsatzkräften - Teil 2: Test im Werk für neue, umgebaute und instandgesetzte Fahrzeuge

Dieses Dokument gilt für die Messung der Radaufstandskräfte von Schienenfahrzeugen in Instandsetzungswerkstätten und an Produktionsstätten. Es behandelt außerdem abgeleitete Größen, die zur Beschreibung der Radaufstandskraftverteilung des Fahrzeugs verwendet werden.
Das Dokument legt die Beurteilungs- und Zulassungskriterien für den Messprozess fest. Die Anforderungen für diese Beurteilung unterstützen die Spezifikation, die Auslegung und die Durchführung des Messprozesses. Es wird berücksichtigt, dass die Messungen entweder statisch oder quasi-statisch erfolgen. Dieses Dokument gilt für alle Schienenfahrzeuge.
Das kommerzielle Wiegen von Fahrzeugen fällt nicht in den Anwendungsbereich dieses Dokuments, in dem auch nicht festlegt wird, in welchen Fällen die Radaufstandskräfte eines Fahrzeugs gemessen werden.

Applications ferroviaires - Mesurage des forces verticales à la roue et à l'essieu - Partie 2 : Essai en atelier des véhicules neufs, modifiés ou maintenus

Le présent document s'applique à la mesure des charges verticales aux roues des véhicules ferroviaires dans les ateliers de maintenance et sur les sites de fabrication. Il aborde également les grandeurs dérivées utilisées pour décrire la répartition des charges verticales aux roues d’un véhicule.
Ce document définit les critères d'évaluation et d'acceptation pour le processus de mesure. Les exigences d'évaluation portent sur la spécification, la conception et le fonctionnement du processus de mesure. On considère que les mesures sont réalisées de manière statique ou quasi statique. Le présent document s'applique à tous les véhicules ferroviaires.
Le poids en service commercial des véhicules n'est pas couvert par le domaine d'application du présent document, lequel ne définit pas non plus dans quels cas les charges aux roues d'un véhicule sont mesurées.

Železniške naprave - Meritve vertikalnih kolesnih in osnih obremenitev - 2. del: Preskus v delavnici za nova, spremenjena in vzdrževana vozila

Ta evropski standard se uporablja za merjenje vertikalnih kolesnih obremenitev železniških vozil v vzdrževalnih delavnicah in proizvodnih obratih. Obravnava tudi izpeljane količine, ki se uporabljajo za opis porazdelitve vertikalne obremenitve koles vozila.
Standard določa kriterije za ocenjevanje in sprejemljivost merilnega postopka. Zahteve za to oceno podpirajo specifikacijo, zasnovo in delovanje merilnega postopka. Meritve se opravljajo bodisi statično bodisi kvazistatično. Ta standard se uporablja za vsa železniška vozila.
Komercialno tehtanje vozil ne spada na področje uporabe tega standarda niti ne določa, v katerih primerih bodo merjene kolesne obremenitve vozila.

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 October 2019, and conflicting national standards shall
be withdrawn at the latest by October 2019.

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
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.
This document is the second part of a three-part standard collectively referred to as Railway
applications — Measurement of vertical forces on wheels and wheelsets and which covers:
— static and quasi-static wheel force measurements of new, modified or maintained rail vehicles in
workshops and
— the evaluation of derived quantities such as the vertical wheelset forces, axle loads and other
quantities that describe the vertical wheel force distribution of a vehicle.
Part 1: On-track measurement sites for vehicles in service deals with the measurement of wheel forces
and axle loads of in-service rail vehicles.
Part 3: Approval and verification of on-track measurement sites for vehicles in service (CEN/TR) is in
preparation and deals with the approval and verification of local measuring sites in-service.
A migration rule is specified in Annex G.
