Introduction
This document is a type-C standard as specified in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this document. These hazards are specific to slurry tankers.
Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-
mounted and trailed) are dealt with in EN ISO 4254-1.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.
The requirements of the European Directive on pressure equipment will be dealt with by the revision of
this standard.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.

verification for the design and construction of semi-mounted, trailed and self-propelled slurry tankers,
including their spreading or injecting devices, intended for handling and transporting and/or distributing
slurry which are operated by either pneumatic or mechanical power. In addition, it specifies the type of
information on safe working practices to be provided by the manufacturer.
When requirements of this document are different from those which are stated in EN ISO 4254-1, the
requirements of this document take precedence over the requirements of EN ISO 4254-1 for machines
that have been designed and built according the provisions of this document.
This document, taken together with EN ISO 4254-1, deals with all the significant hazards, hazardous
situations and events relevant to slurry tankers, when they are used as intended and under the conditions
of misuse which are reasonably foreseeable by the manufacturer (see Table A.1), excepting the hazards
related to road safety (e.g. steering, braking).

4.2.3.4 Stability of the boom when parked and for manual handling
The boom shall be designed to be stable when parked according to the information in the instruction
handbook on firm ground with an inclination of at least 8,5° in all directions.
Where transport rollers are fitted to the boom for ease of manual handling when detached from the
tanker, the boom and the location of these rollers shall be designed so that the boom is stable and will not
overturn during such handling.
Compliance with this requirement shall be verified as follows: Place the boom, which has been parked in
accordance with the information in the instruction handbook, on a horizontal and even plane. Then push
it at a speed of 1 m/s against a fixed rectangular obstacle 50 mm high with a length at least equal to the
distance between the external transport rollers and located on the ground at a right angle to the direction
of movement of the boom.
The boom shall remain upright.
On booms fitted with transport rollers for ease of manual handling, devices shall be provided for avoiding
unintended rolling away.
4.2.4 Means of access and place to stand
If, during normal operation, access is required by the operator to the upper part of the tank (e.g. for access
to opening(s), to routinely clean a tube style level indicator), means of access complying with
EN ISO 4254-1:2015, 4.8 shall be provided.
Locations that need to be reached for the normal operation of the machine and are not accessible from
the ground (e.g. distributor of drip hose boom, tank openings, cutting devices, foreign object separators)
shall be equipped with access means and platforms according to EN ISO 4254-1:2015, 4.7.2 and 4.8.
Parts of the spreading or injecting boom shall not be used as handholds related to the means of access.
4.2.5 Hydraulic, pneumatic and electrical interconnections
When the hydraulic braking system of the tanker is intended to be coupled to the tractor service braking
system, then the coupling defined in ISO 5676 shall be used. This coupling shall only be fitted in the
braking circuit. For pneumatic braking, see ISO 1728:2006.
4.2.6 Stability and immobilisation of the tanker
4.2.6.1 Stability
4.2.6.1.1 Dynamic stability
During travelling, sufficient stability shall be provided. This requirement is deemed to be fulfilled if the
static tipping angle is at least 23° about the most unfavourable axis of the machine. The determination
and verification of the tipping angle can be by calculation or by test with the machine fully laden.
NOTE More details regarding the description of the test procedure will be provided by an amendment.
4.2.6.1.2 Static stability
4.2.6.1.2.1 Ground pressure
When the tanker is parked on a horizontal surface, containing a uniform load equal to the maximum
permissible load declared by the manufacturer, any supporting devices other than wheels shall have a
bearing surface designed to limit the ground pressure to a maximum of 400 kPa, according to
EN ISO 4254-1:2015, 6.2.1.2.

4.2.6.1.2.2 Immobilisation (parking brake)
Tankers shall be provided with a parking brake.
The parking brake system with which the tanker is equipped shall be capable of holding the laden
detached tanker stationary on an 18 % up and down gradient.
Verification: by standing the tanker, loaded at its maximum permissible load, and with any steerable
axles in the most unfavourable position on a firm surface with a gradient of 18 %. The slurry tanker shall
be positioned with its forward direction of travel facing up the gradient with the parking brake applied
and providing the only means of restraint, the slurry tanker shall not move. The test shall be repeated
with the forward direction of travel facing down the gradient.
During the test, the tanker shall not move.
If blocks are provided with the tankers, a location shall be provided on the tanker for their storage when
they are not used.
This device shall be designed to secure the chocks so they cannot detach from the tanker unintentionally
or move freely when the tanker is in motion.
The wheel chocks need to be safe to operate and be easily accessible from outside the contour of the
machine. Hooks or chains shall not be used as a device for storage/fixation. The device should preferably
be in the front or in close proximity to the wheels.

4.2.7 Jacking points
Jacking points shall be designed and provided according to EN ISO 4254-1:2015, 5.2.3.
4.2.8 Protection against risks associated with overhead power lines
4.2.8.1 Spreading or injecting booms
To limit the risks associated with overhead power lines, the booms shall be capable of folding and
unfolding without exceeding a height of 4 m. This requirement:
— does not apply during release of the folded components from the transport position, and during
positioning of the folded components into the transport position;
— shall be verified by measurement as follows: the height of 4 m shall be measured with the machine
on horizontal level ground.
When a height of 4 m can be exceeded during folding or unfolding of parts, a label shall be affixed to the
machine to inform the operator about the heights of the folding parts achievable and potential hazard of
contact with powe
