Agricultural and forestry machinery - Inspection of sprayers and liquid fertilizer distributors in use - Part 3: Sprayers for bush and tree crops (ISO/DIS 16122-3:2011)

This European Standard specifies the requirements and methods of their verification for the inspection of air-assisted sprayers for bush and tree crops in use. It relates mainly to the condition of the sprayer in respect of safety hazards for the test operator, the potential risk of environmental contamination and opportunities to achieve good application.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
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 possibility 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 16122-3 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 6, and by Technical 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 machinery —
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.

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 necessary to define the
requirements and test methods for sprayers in use. This is a relevant step after having standardized the
requirements for new equipment, in respect of safety hazards (see ISO 4254-6) 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 the execution management of the inspection, which
organizations are authorized to carry out the inspection, 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 air-assisted sprayers for
bush and tree crops in use. Developments in this direction have been stimulated by public concern about
risks, and the aim of reducing the use of crop protection products.

Part 3:
Sprayers for bush and tree crops
1 Scope
2)
This International Standard, to be used together with ISO 16122-1 specifies the requirements and test
methods for the inspection of sprayers in use for bushes and tree crops, including pneumatic sprayers, gun
sprayers, and specific sprayers used in vegetables crops (i.e. tomatoes, pepper,… which can be considered
as bushes).
It relates mainly to the condition of the equipment with respect to its potential risk for the environment 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.
