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.

and forestry, Subcommittee SC 6, Equipment for crop protection.

Introduction
There are three main reasons for inspection in 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 pests with the minimum possible input of PPPs.
In order to use PPPs in agricultural production safely, it is necessary to define the requirements
and test methods for knapsack sprayers in use. 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 and −2).
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 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 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 regional regulations may also apply concerning the qualifications and competence of
inspectors.

Equipment for crop protection — Knapsack sprayers —
Part 3:
Inspection of knapsack sprayers in use
1 Scope
This part of ISO 19932 specifies the requirements and test methods for the inspection in use of Knapsack
sprayers carried on the back or shoulder of the operator for use with Plant Protection Products (PPPs).
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 primarily in agriculture, forestry and horticulture, with a nominal volume of more
than 6.0 l.
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 does not apply to knapsack combustion engine-driven air-blast sprayers according to ISO/DIS 28139,
Controlled Droplet Application equipment utilising rotary atomisers, or portable application equipment
for spatial application (e.g. foggers).
