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 document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 6, Equipment for crop protection, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 144, Tractors and machinery for agriculture and forestry,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 16122-3:2015), which has been technically
revised.
The main changes are as follows:
— removed errors and resolve contradictions to the ISO 16119 series which specifies environmental
requirements for new sprayers;
— updated the normative references;
— modified the terms and definitions;
— modified the testing capacity of the spraying pump;
— modified the tank filling strainer/Filling hole;
— modified the tank emptying (modified);
— modified the controls;
— modified the diameter analogue pressure indicators;
— modified the maximum error flow-meters for controlling the volume/hectare rate;
— modified dripping;
— modified spray guns and lances;
— modified the pump capacity test.

Introduction
There are two main reasons for the inspection of sprayers:
— reducing the 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 document, 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.
The terms and definitions for specific sprayers in the relevant specific parts.
NOTE National or local regulations concerning the qualifications and competence of inspectors can apply.
