Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

ISO 16122-3:2015(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).
Standardising 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.

Part 3:
Sprayers for bush and tree crops
1 Scope
This part of ISO 16122, when used together with ISO 16122-1, specifies the requirements and test
methods for the inspection of sprayers for bushes and trees, when in use.
The requirements relate mainly to the condition of the sprayer with respect to its potential risk for the
environment and its performance to achieve a good application.
NOTE Requirements for the protection of inspectors during an inspection are given in ISO 16122-1.

The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

For the purposes of this document, the terms and definitions given in ISO 16122-1 and the following
apply.
3.1
sprayer for bush and tree crops
machine for spraying plant protection products on bush and tree crops such as grapes, fruits or hops
(including annual plants/crops), the application being mostly directed sideways and/or upwards to the
target
Note 1 to entry: Characteristics of sprayers for bushes and tree crops are specified in ISO 16122-1:2015, Table A.1.
3.2
plant protection product container
collective name for plant protection product packaging
EXAMPLE Can, bottle, bag, sack, box.
3.3
cleaning device
device for cleaning the inside of empty plant protection product containers

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 distance between the spray nozzles to the target to be sprayed, in the 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.
