BS EN 16185-2:2014

National foreword
This British Standard is the UK implementation of EN 16185-2:2014.
The UK committee draws users’ attention to the distinction between
normative and informative elements, as defined in Clause 3 of the
CEN/CENELEC Internal Regulations, Part 3.
Normative: Requirements conveying criteria to be fulfilled if
compliance with the document is to be claimed and from which no
deviation is permitted.
Informative: Information intended to assist the understanding or use
of the document. Informative annexes do not contain requirements,
except as optional requirements, and are not mandatory. For
example, a test method may contain requirements, but there is no
need to comply with these requirements to claim compliance with
the standard.
When rounded values require unit conversion for use in the UK,
users are advised to use equivalent values rounded to the nearest
whole number. The use of absolute values for converted units should
be avoided in these cases. For the values used in this standard:

Requirements
General

The tests defined in this European Standard shall be carried out and the results used to verify that the braking
performance and functions of the MU brake system, as a minimum, comply with the requirements of
EN 16185-1. 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 MU that is representative of the design/type of the MU being approved;

—

routine tests which are carried out on each and every example of the approved design/type of 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.

It is expected that tests for the purpose of vehicle acceptance are strictly selected from the list of type tests
and performed by a body accredited in accordance with EN ISO/IEC 17025.
The type and routine tests are as follows:
—

6

tests with one MU (Level 2): these tests serve to check the common functions of the MU and the
interfaces between the vehicles which comprise the MU;


BS EN 16185-2:2014
EN 16185-2:2014 (E)

—

tests with two or more coupled MU’s (Level 3) up to the maximum MU configuration: these tests serve to
check the common functions of the MU composition and the interfaces between the MUs.

It is sufficient to carry out coupled Multiple Units testing in the tare load state only but with the maximum
number of coupled vehicles (unless otherwise specified).
Figure 1 gives an example of the levels.

9

BS EN 16185-2:2014
EN 16185-2:2014 (E)

—

application forces and brake application time on sufficient vehicles and in sufficient locations to be able to
assess the impact that variables in these parameters have on the overall brake performances (for type
tests only);

—

wheels diameter.

6.4

Methodology (for type tests only)

6.4.1

Measurement of the friction application force

The friction application force may be determined using either of the following methods:
—

direct measurement of the application force on sufficient vehicles and in sufficient locations on each
actuator;

—

measurement of the brake cylinders pressure, on sufficient vehicles and in sufficient locations on each
actuator, providing the relationship between brake cylinder pressure and application force is known.

6.4.2

Measurement of the delay time

The brake application and release delay time can be directly measured either obtained as a difference
between response time and application force build-up or application force release time.
In case of direct measurement an electrical signal shall be recorded as initiating event e.g. a switch confirming
that the brake handle reached the specified position.
6.4.3

Measurement of the application force build-up time

In a pneumatic brake system the application force build-up time shall be measured at the brake cylinder which
is the furthest from of the brake panel which controls it. It is accepted to add a T-connection for the type test.
For the routine tests of the MU equipped with variable load relay valves, measurement may be taken of the
automatic or indirect brake pilot pressure providing suitable allowances are incorporated to account for any
time differences.
6.4.4

Measurement of the application force release time

In a pneumatic brake system the application force release time shall be measured at the brake cylinder which
is the furthest from of the brake panel which controls it. It is accepted to add a T-connection for the type test.
For the routine tests of the MU equipped with variable load relay valves, measurement may be taken of the
automatic or indirect brake pilot pressure providing suitable allowances are incorporated to account for any
time differences.

In any case the full release at the brake cylinder shall be verified.
6.4.5

Measurement of the brake response time

The brake response time can be directly measured or calculated
a)

by adding together the delay time and application force build-up time during brake application or

b)

by adding together the delay time and application force release time during brake release.

6.4.6 Measurement of the pressure drop time in the brake pipe or the equalising reservoir of the
driver’s brake valve
The pressure drop time shall be measured from 5 bar to 3,5 bar, but the pressure drop actually created during
the test is to be from 5 bar to 3,2 bar.

10


BS EN 16185-2:2014
EN 16185-2:2014 (E)

6.4.7 Measurement of the pressure rise time in the brake pipe or the equalising reservoir of the
driver’s brake valve
The pressure rise time shall be measured from 1,5 bar below the set value to 0,1 bar below the set value
(normally from 3,5 bar to 4,9 bar).
6.4.8

Measurement of the dead time of the WSP dump valves

The dead time for exhaust and fill shall be measured from the command to fill or release to 5 % pressure
variation at the brake cylinder. This is measured:
—

with emergency brake applied (in order to have the maximum brake cylinder pressure);

—

fully venting the brake cylinder while measuring the exhaust dead time;

—

fully re-filling the brake cylinder while measuring the fill dead time;

at the brake cylinder which is furthest away from the dump valve which controls it.
6.4.9

Measurement of the exhaust time of the WSP dump valves

The exhaust time shall be measured from the maximum stabilized pressure at the brake cylinder down to
0,4 bar. This is measured at the brake cylinder of the vehicle which is furthest away from the dump valve
which controls it. It is accepted to add a T-connection for the type test.
6.4.10 Measurement of the fill time of the WSP dump valves
The fill time shall be measured from 0 % to 95 % of the maximum stabilized pressure at the brake cylinder.
This is measured at the brake cylinder of the vehicle which is furthest away from the dump valve which
controls it.
6.4.11 Measurement of air tightness

When carrying out pressure leakage tests, sufficient time shall be allowed for pressure stabilization before
starting timing measurements.
6.4.12 Measurement of braking and release times of EP assist brake
The time taken to achieve a local brake pipe pressure change shall be verified on each vehicle with the BP
first being pressurized and then shut-off and with normal main reservoir pipe pressure.
The braking solenoid valves shall be energised and the time taken for the brake pipe pressure to reduce over
1,5 bar from the Set Value (normally from 5 bar to 3,5 bar) shall be measured and recorded.
The release solenoid valve shall be energised and the time taken for the brake pipe pressure to increase from
1,5 bar below the set value to 0,1 bar below the set value (normally from 3,5 bar to 4,9 bar) shall be measured
and recorded.
6.4.13 Evaluation of the longitudinal brake force applied to the track by Magnetic Track Brake or
Eddy Current Brake
The longitudinal force shall be evaluated for emergency brake application and if applicable also for full service
brake application from maximum speed under tare and load conditions.
The longitudinal force for the Magnetic Track Brake or Eddy Current Brake shall be calculated from the
deceleration achieved using these brakes. This deceleration shall be calculated as the difference between the
decelerations which are measured for brake applications with and without the Magnetic Track Brake or Eddy
Current Brake applied.
