Agricultural machinery - Safety - Part 6: Sprayers and liquid fertilizer distributors (ISO 4254-6:2020)
This document, to be used together with ISO 4254-1, specifies the safety requirements and their
verification for the design and construction of mounted, semi-mounted, trailed and self-propelled
agricultural sprayers for use with plant protection products (PPP) and liquid fertilizer application,
as placed on the market by the manufacturer and designed for a single operator only. In addition, it
specifies the type of information on safe working practices (including residual risks) to be provided by
the manufacturer.
When requirements of this document are different from those which are stated in ISO 4254-1, the
requirements of this document take precedence over the requirements of ISO 4254-1 for machines that
have been designed and built according to the provisions of this document.
This document, taken together with ISO 4254-1, deals with significant hazards, hazardous situations
and events relevant to sprayers and liquid fertilizer distributors when they are used as intended and
under the conditions foreseeable by the manufacturer (see Annex A), excepting the hazards arising from:
— protection of the driver against spray when spraying (see Foreword);
— automatically actuated height adjustment systems;
— the environment, other than noise;
— moving parts for power transmission except strength requirements for guards and barriers.
This document is not applicable to sprayers and liquid fertilizer distributors which are manufactured
before the date of publication of this document.

other standards for machines that have been designed and built according to the requirements of this
type‑C standard.
The machinery concerned and the extent to which hazards, hazardous situations and events are
covered are indicated in the scope of this part of ISO 4254. These hazards are specific to sprayers and
liquid fertilizer distributors.
Significant hazards that are common to all the agricultural machines (self‑propelled, mounted, semi‑
mounted and trailed) are dealt with in ISO 4254-1.

Agricultural machinery — Safety —
Part 6:
Sprayers and liquid fertilizer distributors
1 Scope
This part of ISO 4254, to be used together with ISO 4254‑1, specifies the safety requirements and their
verification for the design and construction of mounted, semi‑mounted, trailed and self‑propelled
agricultural sprayers for use with Plant Protection Products (PPP) and liquid fertilizer application,
as placed on the market by the manufacturer and designed for a single operator only. In addition, it
specifies the type of information on safe working practices (including residual risks) to be provided by
the manufacturer.
When requirements of this part of ISO 4254 are different from those which are stated in ISO 4254-1,
the requirements of this part of ISO 4254 take precedence over the requirements of ISO 4254‑1 for
machines that have been designed and built according the provisions of this part of ISO 4254.
This part of ISO 4254, taken together with ISO 4254‑1, deals with significant hazards, hazardous
situations and events relevant to sprayers and liquid fertilizer distributors when they are used as
intended and under the conditions foreseen by the manufacturer (see Annex A), excepting the hazards
arising from:
— automatically actuated height adjustment systems;
— the environment, other than noise;
NOTE For environment related hazards, see ISO 16119.
— moving parts for power transmission except strength requirements for guards and barriers;
This part of ISO 4254 is not applicable to sprayers and liquid fertilizer distributors which are
manufactured before the date of publication of this document by ISO.

oSIST prEN ISO 4254-6:2017
ISO/DIS 4254-6:2017(E)
4.4.2 Booms that can be manually folded/unfolded shall be fitted with two handles located at a
distance of at least 300 mm from the nearest articulation. These handles may be integral parts of the
boom, provided they are ergonomically designed and clearly identified.
In the case of powered folding/unfolding operation, the control shall be of the hold‑to‑run type and the
manual control shall be located outside the swiveling zone.
A device shall be provided to prevent the boom from moving when it is in the transport position. If
this locking device is a hydraulic valve not directly fitted to the cylinder, the lines connecting the valve
to the cylinder shall be designed to withstand a pressure of at least four times the rated maximum
hydraulic pressure. See also (7.1 d)). The unlocking and the unfolding of booms shall be controlled by
means of separate actions by the operator.
4.5 Adjustment of spray boom height
The manual force necessary to adjust the height of the boom shall not exceed 250 N.
Where height adjustment is by a mechanical device, this device shall be self‑arresting and able to deal
with a nominal load equal to at least 1,3 times the weight of the boom.
This mechanical device shall be operable from the ground or from a platform as specified in
ISO 4254-1:2013, 4.7.2.
In the case of powered height adjustment systems that are manually actuated, it shall be possible to
actuate the manual control from the driver’s position and the control shall be of the hold‑to‑run type.
In the case of powered height adjustment systems that are automatically actuated, it shall be possible to
override the system from the driver’s position.
To ensure the protection of the operator against crushing and shearing hazards related to a failure of
the control circuit of the height adjustment of the boom, the machine shall be fitted for those purposes
with either
-1
a) a device which limits the maximum downward speed of the boom to 10 mm⋅s (measured at the
centreline of the machine) during a hydraulic failure, or
b) a device capable of stopping the boom lowering at a minimum height of 500 mm between the boom
and the ground.
For b), in those cases where the height needs to be reduced to less than 500 mm, a safety device shall
prevent any lowering beneath the chosen height, and it shall only be possible to reduce the height by
means of an intentional and separate action.
If these safety devices are hydraulic valves not directly fitted to the cylinder, the lines connecting the
valve to the cylinder shall be designed to withstand a pressure of at least four times the rated maximum
hydraulic pressure.
4.6 Spray tank
4.6.1 Prevention of whole-body access to the tank
To limit the risk of access into the tank, any tank opening greater than 400 mm in diameter — or, if
it is rectangular, of more than 400 mm × 300 mm — shall be provided with a grating which can only
be removed by the use of tools. The openings in the grating shall not exceed the above‑mentioned
dimensions. See also 6.1 g) and 6.2.2.
4.6.2 Limitation of contact with chemicals
To limit the risk of exposure to chemicals during filling/cleaning operations 4.6.2.1, 4.6.2.2 or 4.6.2.3
shall be applied.

4.6.2.1 Chemical induction bowls which are folded/unfolded manually shall be provided with a handle
and locking mechanism for folding/unfolding that can be actuated without presenting a risk to the
operator during operation. The handle can be integral part of the chemical induction bowl provided it is
suitably designed and clearly identified.
Power-assisted chemical induction bowls shall be able to be operated from a position that prevents
the operator contacting the folding induction bowl while operating the folding control. The folding
control shall be a hold-to-run control. The unintended unfolding of the chemical induction bowl during
transport shall be prevented by a suitable means.
Actuation of the PPP container rinsing device shall be operated by a hold‑to‑run control, the purpose
of which is to prevent operation of the rinsing device unless a PPP container is correctly positioned on
the device, prevents the discharge of liquid onto the operator and all liquid released is directed into the
induction system, no liquid shall be ejected outside of the induction system.
4.6.2.2 The filling hole of the spray tank shall be so positioned that the height from the ground or
platform is not more than 1 300 mm, with the horizontal reach between the rim of the hole and the outer
edge of any part of the sprayer which could hinder the operator being not more than 300 mm at the
operator filling position (see Figure 1).
4.6.2.3 In case of liquid PPP, the sprayer shall be equipped with a means for introducing PPP’s that
control the risk of chemical contact and inhalation when dispensing PPP’s and when cleaning the PPP
container (see e.g. closed transfer systems).
NOTE A closed transfer systems standard is under development.

— fitted with a holding device ensuring a closed position either by means of a positive mechanical
action or lids fixed by screwing;
— fitted so as to prevent leakage of the spray mixture, e.g. by means of a seal.
The level of liquid shall be indicated to the operator during filling and emptying. The nominal volume of
the tank shall be marked.
A pressure‑compensation device shall be fitted on tanks that are not designed to be put under pressure,
in order to keep them at atmospheric pressure when emptying and filling.
4.6.4 Protection from contact with spray mixture when draining
The operator shall be prevented from coming into contact with the spray mixture when emptying the
tank. This requirement is met if
— the draining outlet can be opened without a tool (for example by means of a tap), and
— the flow is directed away from the operator.
An emptying device shall allow the complete emptying of the residue in the tank when the sprayer is in
a horizontal position.
It shall be possible to collect the liquid at the outlet without contaminating the operator or
equipment parts.
The tank outlet shall be guarded against accidental opening (see ISO 16119‑2:2013, 5.1.1.3.2).
See also 6.1 g) and 6.1 k).
4.7 Pressure indicator (manometer)
The sprayer shall have a pressure indicator. The design of the pressure indicator shall be such that in
case of a leakage there is no unreasonable hazard for the operator. This requirement is deemed to be
fulfilled if either
— spray liquid carrying hoses are not located in the operator cabin, or
— additional protection shall be provided, e.g. by imperforate covers completely covering the hoses
and their connecting devices so that exposure of leakage to the operator shall be avoided.
The working pressure(s) shall be clearly readable from the driver’s position. Turning of the head and
the upper body is acceptable.
For analogue pressure gauges, the minimum diameter of pressure gauge dial plate shall be:
— 63 mm where the gauge is connected to controls and positioned within the hand reach of the
operator or between the plane formed by the hitch points of the three‑point linkage and the tractor;
— 100 mm in all other cases.
The gauge case shall be isolated from the spray mixture.
Pressure exceeding the maximum working pressure shall be indicated — for example, on the analogue
pressure gauge by a red marking and on a digital instrument by an (audible or optical) indication
initiated when the pressure reaches the maximum working pressure. See also 6.1 m).
4.8 Protection against overpressure
The sprayer shall be provided with a safety device that prevents the pressure from exceeding the
maximum working pressure of the circuit by more than 20 %.

The adjustment of this safety device shall be protected against unauthorized or accidental modification.
Its actuation shall not cause any spillage or leakage of liquid from the circuit.
4.9 Product fan
If a sprayer is equipped with a product system fan, the following requirements apply:
— the fan shall be placed or protected so that when the sprayer is operating it shall not be able to draw
in or discharge foreign matter which could injure the operator;
— access to the fan shall be prevented by fixed guards, which may be a combination of imperforate and
mesh guards whose apertures conform to requirements of ISO 13857:2008, Tables 1, 3, 4 and 6;
— when the fan drive is not controlled independently from the pump drive, it shall be possible to
disengage the fan drive from the pump drive from the ground or from a platform.
See also 6.1 h).
4.10 Spray liquid carrying hoses
To avoid hazards to the operator in case of leakage
— hoses shall not be located in the operator cabin, or
— hoses and their connecting devices shall be protected (e.g. by imperforate screens).
All pressurized hoses shall be directly and durably marked with the maximum working pressure.
The maximum working pressure of hoses and the maximum working pressure of connecting devices
shall be at least equal to the maximum working pressure of the circuit [see also 6.1 m), 6.2.3 and 6.2.4].
4.11 Spraying stop control
Each machine shall be equipped at the operator’s position with a spraying stop control device to safely
stop the flow (e.g. by means of two valves placed in series). When the spraying stop control has been
activated, there shall be no dripping.
4.12 Clean water tank
Sprayers shall be equipped with a clean water tank for the operator’s use (e.g. in case a person has been
in contact with chemicals) having a minimum capacity of 15 l. This tank shall be totally isolated from
