ISO/DIS 16122-2
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 repr esented 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of techni cal committees is to prep are International Standards. Draft International Standa rds
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the p ossibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16122-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 6, and by Techni cal Committee CEN/TC 144, Tractors and machinery for
agriculture and forestry in collaboration.
ISO 16122 consists of the following parts, under the general title Agricultural and forestry machines —
Inspection of sprayers and liquid fertilizer distributors in use:
⎯ Part 1: General
⎯ Part 2: Horizontal boom sprayers and similar
⎯ Part 3: Sprayers for bushes and tree crops and similar.
Fixed and semi-mobile sprayers are to form the subject of a future Part 4.

ISO/DIS 16122-2
Introduction
There are two main reasons for the inspection:
⎯ less potential risk of environmental contamination by crop protection products;
⎯ good control of the pest with the minimum possible input of crop protection product.
In order to use crop protection products in agricultural production safely, it is ne cessary to define the
requirements and test methods for sp rayers in use. Th is is a relevant step after having standa rdized the
requirements for new eq uipment, in respect of safety hazards (see ISO 4 254-6) and potential risks of
1)
environmental contamination (see ISO 16119 Parts 1 to 3 ).
Standardising the requirements and methods for inspection of sprayers in use, takes into consideration not
only the original performance of the spraying equipment, but also its use, care and maintenance. This is the
logical link between new equipment of good quality and well educated and concerned users.
The inspection of sprayers in use can be done on a voluntary or mandatory basis. In both cases further official
or legal specifications are necessary, e.g. on th e execution management of the in spection, which
organizations are authorized to carry out the insp ection, time intervals between inspections etc. As the
specifications of this International Standard are based on ISO 4254-6 and ISO 16119, it may be the case that
sprayers in use which were produced before ISO 4254-6 and ISO 16119 were published do not fulfil all the
specifications given in this International Standard.
During recent years, several countries have developed systems for inspection of horizontal boom sprayers in
use Developments in this direction ha ve been stimulated by public co ncern about risks, and the aim of
reducing the use of crop protection products.

DRAFT INTERNATIONAL STANDARD ISO/DIS 16122-2

Agricultural and forestry machinery — Inspection of sprayers
and liquid fertilizer distributors in use —
Part 2:
Horizontal boom sprayers and similar
1 Scope
2)
This International Standard, to be u sed together with ISO 16122-1 , specifies the requirements and test
methods for the inspection of horizontal boom sprayers and similar in use.
It relates mainly to the condition of the equipment with respect to its potential risk for the en vironment and its
performance to achieve good application. A summary of the inspection is given in Annex A.
Regarding inspector (test operator) safety, minimum requirements are necessary to perform the test of the
sprayer without hazardous situation for the inspector, see Clause 4 of ISO 16122-1
It does not deal with safety valve's check.

3 Term and definition
For the purposes of this document, the term and definition given in ISO 16122-1 and the following apply.
3.1
horizontal boom sprayers and similar
ground vehicle mounted sprayers designed for the application of pesticides or fertilisers primarily on ground,
low plants / crops, in a liquid form. It includes band sprayers. The application is usually directed downwards to
the target and is generally made with nozzles mounted on a horizontal sprayer boom
NOTE Characteristics of horizontal boom sprayers and similar are specified in Table A.1 of ISO 16122-1.

4 Requirements and method of verification
4.1 Pump
4.1.1 Capacity
The pump capacity shall be suited to the needs of the equipment.
The pump shall have sufficient flow rate cap acity in order to be able to sp ray while maintaining a visible
agitation as specified in 4.2.
Method of verification: measurement according to 5.1.a) or 5.1b).
4.1.2 Pulsations
The pump shall not cause excessive pulsations. The pulsations shall not exceed 5% of the working pressure.
Method of verification: visual check and function test.
4.1.3 Air chamber
If an air chamber is present, the air pressure shall be from 30 % to 70 % of the sprayers working pressure.
The membrane shall not be damaged (no liquid shall appear when testing the pressure valve)
Method of verification: function test and measurement.
4.1.4 Leakages
There shall be no leakages (e.g. dripping) from the pump.
Method of verification: visual check.
4.2 Agitation
4.2.1 Hydraulic
A clearly visible agitation shall be maintained when spraying at maximum working pressure as recommended
by the sprayer or nozzle manufacturer – whatever is the lower – during test with the large st nozzles mounted
on the boom, and pump revolution as recommended by the sprayer manufacturer, with the tank filled to the
half of its nominal capacity.
