ISO 16122-2:2015(E)
Introduction
There are two main reasons for the inspection:
— less potential risk of environmental contamination by plant protection products;
— good control of the pest with the minimum possible input of plant protection product.
In order to use plant protection products in agricultural production safely, it is necessary to define the
requirements and test methods for sprayers in use. This is a relevant step after having standardized
minimum requirements for new sprayers, in respect of safety hazards (see ISO 4254-6) and potential
risks of environmental contamination (see ISO 16119 series).
Standardizing the requirements and methods for inspection of sprayers in use, takes into consideration
not only the original performance of the sprayer but also its use, care and maintenance. This is a logical
link to ensure the continued benefit arising from the supply of new sprayers of good quality.
The inspection of sprayers in use can be a mandatory requirement or adopted on a voluntary basis. In
both cases further requirements, outside the scope of this standard, are necessary for the management
of inspections. These include, for example, requirements for the competence of persons carrying out
inspections and the frequency of inspections.
NOTE National or local regulations may also apply concerning the qualifications and competence of
inspectors.

ISO 16122-2:2015(E)
4 Requirements and method of verification
4.1 Leaks and dripping
4.1.1 Static leaks
The sprayer shall be filled with water to its nominal capacity.
With the pump not running and the sprayer parked on a level horizontal surface, a visual inspection for
any leakage from the tank, pump and associated pipes shall be carried out.
For high capacity tanks, water filling can be reduced to no less than half of the nominal tank volume,
provided an additional inspection of the tank is carried out in order to identify any cracks, holes or other
damage that can cause leakage.
Compliance shall be checked by inspection.
4.1.2 Dynamic leaks
4.1.2.1 Leak test when not spraying
With the sprayer running at a pressure which is equal to the maximum obtainable pressure for the
system, with the section valves closed, there shall be no leakage from any part of the sprayer.
Compliance shall be checked by inspection.
4.1.2.2 Leak test while spraying
While spraying at a pressure that is equal to the maximum working pressure recommended by the
sprayer manufacturer, or the nozzle manufacturer for the nozzles mounted on the sprayer if lower, there
shall be no leakage from any part of the sprayer or spray boom.
Compliance shall be checked by inspection.
4.1.3 Spraying and dripping on parts
Regardless of the height of the boom above the ground, in the height range between the nozzles and the
target surface, no liquid shall be sprayed directly on to the sprayer itself (e.g. parts of the sprayer, hoses).
This does not apply if needed by function (e.g. sensors) and if dripping is minimised.
Compliance shall be checked by inspection and function test.
4.2 Pump(s)
4.2.1 Capacity
The pump capacity shall be suited to the needs of the sprayer.
a) The pump capacity shall be at least 90 % of its original nominal flow given by the sprayer
manufacturer or another minimum pump capacity given by the sprayer manufacturer.
Compliance shall be checked by measurement according to 5.2.1.2.2 or 5.2.1.2.3.
b) Or, alternatively, the pump(s) shall have sufficient flow rate capacity in order to be able to spray
while maintaining a visible agitation as specified in 4.3.1.
Compliance shall be checked by inspection.

4.2.2 Pulsations
The pulsations shall not exceed 10 % of the working pressure.
Compliance shall be checked by measurement and function test according to 5.2.2.
4.2.3 Air chamber
If an air chamber is present the membrane shall not be damaged, there shall be no appearance of liquid
when operated at the maximum pressure recommended by the sprayer manufacturer. The air pressure
shall be the pressure recommended by the sprayer manufacturer or between 30 % and 70 % of the
working pressure for the nozzles in use.
Compliance shall be checked by function test and measurement.
4.3 Spray mix agitation

— when spraying at the maximum working pressure as recommended by the sprayer or nozzle
manufacturer (whichever is the lower);
— with the largest nozzles mounted on the sprayer;
— with pump rotation speed as recommended by the sprayer manufacturer;
— with the tank filled to half its nominal capacity.
Compliance shall be checked by inspection.
4.3.2 Mechanical
A clearly visible agitation shall be maintained when the agitation system is working as recommended by
the sprayer manufacturer, with the tank filled to half its nominal capacity.
Compliance shall be checked by inspection.
4.4 Spray liquid tank
4.4.1 Lid
The tank shall be provided with a lid that shall be well adapted and in good condition.
This lid shall be tightly sealed to prevent leakage and shall avoid unintended opening.
If a vent is fitted in the lid (according to 4.4.4), it shall prevent spillage.
Compliance shall be checked by inspection.
4.4.2 Filling hole(s)
There shall be a strainer in good condition in the filling hole(s).
Compliance shall be checked by inspection.
ISO 16122-2:2015(E)
4.4.3 Induction hopper

of the operator.
Compliance shall be checked by inspection.
4.4.7 Tank filling
If there is a water filling device on the sprayer, water from the sprayer shall be prevented from returning
to the water source, e.g. by means of a non-return valve.
Compliance shall be checked by inspection and function test.
4.4.8 Cleaning device for plant protection product containers
If provided, the cleaning device for plant protection product containers shall function.
