European foreword
This document (prEN 13452-2:2023) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
This document will supersede EN 13452-2:2003.
EN 13452-2:2003:
— normative references have been updated;
— test requirements have been completely revised;
— wheel slide protection recommendations have been added.
This series EN 13452, Railway applications — Braking – Urban Rail brake systems consists of two parts:
— Part 1: Requirements and definitions
— Part 2: Test methods
Introduction
The objective of this part of the EN 13452 series is to provide the test requirements to demonstrate
accordance with prEN 13452-1:2023.
This document covers the static and dynamic brake type and routine testing of trains or trainsets, but it
does not cover the testing of components or equipment.
Regarding “direct EP brake” and “indirect brake (UIC type)” of prEN 13452-2:2023, which can concern
other urban rail vehicles in accordance with prEN 13452-1:2023, there might be borderline cases which
can also fall within the scope of EN 16185-2.
1 Scope
This document specifies test methods for a brake system for use in urban rail vehicles.
NOTE Urban rail vehicles are defined in EN 17343.
This document is applicable to
— tram vehicles and light rail vehicles,
— metro vehicles with steel wheels,
— metro vehicles with rubber tyred wheels,
— other urban rail vehicles.
This document does not apply to special transport systems, e.g. suspended monorail, rack and pinion
lines, isolated operations such as scenic railways, special duty vehicles, etc.

5 Test requirements
5.1 General
The tests defined in this document shall be carried out and the results used to verify that the braking
performance and functions of the brake system, as a minimum, correspond to the requirements of
prEN 13452-1:2023. This document identifies relevant data to be documented.
This document defines the static and dynamic tests required for the following phases:
— type tests which demonstrate that the brake system conforms to the requirements in all respects:
— these tests are carried out using a tram vehicle/MU that is representative of the design/type
being approved;
— routine tests which are carried out on each example of the approved design/type of tram vehicle/MU
in order to confirm the technical stability of the production processes:
— for this purpose, only the basic features and functions of the system and its sub-systems are
verified.
All routine tests shall be completed successfully prior to the introduction of that train into service.
It is expected that tests for the purpose of vehicle acceptance are strictly selected from the list of type
tests of Annex A.
The type and routine tests shall be performed at different levels as explained below:
— tests with one tram vehicle/MU (train formation level 2):
— these tests serve to check the common functions of the vehicle/trainset and the interfaces
between t
