— Part 2: Requirements for distribution and their test.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of

Introduction
This document is meant to assess the demands made on mobile spreading and spraying machines
operated in traffic.
For simplicity, in this document all machines are called “spreaders” also for liquid agent spraying.
Spreading machines (spreaders/gritters) are meant to be operated in such way that homogeneous
distribution of spreading media is given within the set spreading dosage, width and spreading pattern
track.
The static and dynamic test procedure has the task to test functionality and accuracy of the spreader.
With dynamic testing, the task is also to test the spreading pattern as much as possible under real
conditions. Therefore, the dynamic test is done with trucks driving realistic speeds.
To ensure the repeatability of the results and to limit the expenditure, the tests for the certification are
not done with all possible spreading agents and all possible parameters of the operational area of the
spreader. The salt for the test is limited to three defined test materials, also the brine is defined
(see Clause 5), and the dynamic tests are not done with the highest possible driving speeds. This does
not mean that the spreaders do not work with other materials or higher speeds. If the spreader is bound
to operate with other materials and/or higher speed, this is meant to be tested and adjusted
individually by the customer. Especially when driving at higher speeds, the influences of the driving
turbulences and the truck configuration upon which the spreader is mounted become very strong so
that it makes no sense to test this for the certification independent of the special truck.
1 Scope
This document gives the possibility to certify a model of vehicle-mounted or (trailer) dragged spreading
machines for winter service with standard parameters, leaving the possibility to the manufacturer to
evolve in performances. At the same time, information is given on the minimum content required for
operating manuals.
This document is valid for machines which are used to spread the following media:
— not pre-wetted spreading agent (solid spreading agent);
— pre-wetted spreading agent;
— liquid spreading agent (brine).
The following points are not covered by this document:
— requirements for registration and approval;
— requirements made by automobile manufacturers;
— requirements on EN 15518-3.

5 Test materials
The materials used in Europe for winter maintenance are very different. The sodium chloride (NaCl)
has different granulometry according to the mine or production type, the humidity of these products is
very variable too. For this reason the test shall be done with one or more reference salts with the
characteristic shown in Tables 1 and 2.

The characteristics of the delivered test material shall be guaranteed and verified by the salt supplier.
An official certificate of material delivered by material supplier shall be attached to the test report. A
simple of salt used for test shall be collected and stored in the Institute with the test documentation.
The de-icing material shall be stored protected from atmospheric moisture agent, in order to keep the
original characteristic during storage period.
The concentration of sodium chloride in the brine for pre-wetting or liquid spraying shall be between
20 % and 23 % by weight. This analysis shall be done prior each test.
The measured results shall be corrected according to the real NaCl content in the spreading material.
Each machine can be tested with one or more salts and different humidity, as shown in Tables 1 and 2,
in the certificate the type of salt used for test shall be reported.
6 Certification procedure
6.1 Principle of qualification procedure
The qualification procedure of the spreaders includes two tests types, one static and one dynamic. The
static test enables to check the right quantity, it is realized without moving the spreader. The dynamic
test enables checking the quality of spreading and spraying pattern, it is realized driving the spreader
vehicle during spreading operation on a test area.
According to the type of spreader tested, the qualification procedure sets the functioning parameters of
the machine. These spreading parameters are different for the static and dynamic tests.
Each spreader type, in order to be qualified, shall meet the requirements of the two tests (static and
dynamic).
During a qualification, it is only allowed to change the settings of spreading width, dosage, symmetry,
simulated speed, pre-wet on/off. In case of changing other parameters the whole test procedure shall be
restarted.
It is allowed to make pre-tests in order to be able to choose and test different settings. These tests will
not be taken as qualification tests. The manufacturer shall declare clearly after the pre-tests that he
wants to start with the qualification test procedure. Then only those test runs after this declaration will
count for official qualification and the qualification test requirements become valid.
6.2 Identification and requirements on spreader types
A spreader type includes a spreader and a control box. The spreader and the control box shall be
identified in the manufacturer’s production (for instance: model number), and shall respect
EN 15597-1.
The modification of the components influencing the spreading performances defined in Annex A
involves the definition of a new machine model, a new procedure of qualification shall be realized for
this new model.

The certificate will have one sentence reporting the test related to the spreader type passed as shown in
Table 3.
For the same model, the manufacturer can do different qualifications with different “test
material/spreader type”.
6.3 Procedure of the static test
6.3.1 General
The static test consists to verify, with weighing, the precision and regularity of test material flow and
right quantity. It is realized without moving the spreader, consequently vehicle speeds shall be
simulated.
— The spreader shall conform to EN 15597-1 (general technical information).
— For the spreaders having an auxiliary engine, the manufacturer's advices shall be respected.
— For the spreaders driven by the vehicle hydraulics, EN 15431 shall be applied (respect of the engine
nominal speed).
— For the spreaders driven by the pump mounted on wheel, an independent system will have to
ensure the pump rotation at the speed needed by the test.
— For the spreaders driven by the pump flanged on a vehicle wheel, an independent system will have
to ensure the pump rotation needed by the test, applying a theoretical diameter of the vehicle tire
of 1 m.
For spreaders working with pre-wetted thawing media, the tests shall be done collecting the two media
concurrently but in separate bins (disconnection of injection pipes of the brine). If the nozzle influence
the flow, shall remain mounted on the pipe during the test.
For spreaders working with liquid, the test shall be done collecting liquid of the spraying devices (e.g.
nozzles) related to the spraying width.
The requirements on the methods and equipment are described in 6.3.3.
6.3.2 Description of static qualification tests per spreader type
Tables 4 to 9 show the tests series which have to be realized for each spreader type with different
spreading parameters in order to qualify a spreader type with a test material.
