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 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
There are three main reasons for inspection of the use of knapsack sprayers, which are the most widely
used means worldwide of applying plant protection products (PPPs):
— less potential risk to the operator;
— less potential risk of environmental contamination by PPPs; and
— good control of the pest with the minimum possible input of PPPs.
In order to use PPPs in agricultural production safely, the requirements and test methods for
knapsack sprayers in use should be defined. This is a relevant step after having standardized
minimum requirements for new knapsack sprayers, in respect of safety hazards and potential risks of
environmental contamination (see ISO 19932-1:202X and ISO 19932-2:202X).
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 the
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.
NOTE National or regional regulations can also apply concerning the qualifications and competence of
inspectors.

Part 3:
Inspection of knapsack sprayers in use
1 Scope
This document specifies the requirements and test methods for inspection of the use of knapsack
sprayers carried on the back or shoulder of the operator for use with plant protection products (PPPs).
The requirements relate mainly to the condition of the sprayer with respect to its potential risk to the
operator and the environment and its performance to achieve good application.
It is applicable to lever-operated knapsack sprayers, knapsack compression sprayers and knapsack
sprayers driven by an engine or electric motor using hydraulic pressure atomisation of the spray liquid,
intended for use primar
