EN 13775-2:2003 (E)

Introduction
It is normal practice in all European countries to carry out checks and measurements on the major
components of new and modified freight wagons and bogies. In view of the importance of uniform
criteria for international transport in all European countries, this European Standard has been
prepared.
It is recognized that vehicles may be subject to different dimensional checks resulting from the design
requirements of the equipment fitted to them when it is not included in this series of standards.

1

Scope

This European Standard specifies requirements for measuring freight wagons with bogies. This
ensures that the measuring processes are applied in accordance with uniform criteria. It applies to
new and modified freight wagons with bogies. Provisions going beyond the scope of these
requirements ought to be agreed upon by the contracting parties involved.
The measuring processes relate to the whole or parts of the underframes with or without add-ons if the
geometrical structure does not permit anything else. Where appropriate, other measuring methods not
specified here are necessary and ought to be specified in each individual case. This applies as
appropriate to bogies.

2

Normative references

This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text, and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any
of these publications apply to this European Standard only when incorporated in it by amendment or
revision. For undated references, the latest edition of the publication referred to applies (including
amendments).
