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 19932-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture
and forestry, Subcommittee SC 6, Equipment for crop protection.
This second edition cancels and replaces the first edition (ISO 19932-1:2013), which has been technically
revised.

Introduction
The application of plant protection products with knapsack sprayers should take into consideration
biological, economic, environmental and operator issues.
The aim of this part of ISO 19932 is to specify test methods for the verification of requirements for
equipment to ensure safe use and protect the environment.
Implementation of parts 1 and 2 of ISO 19932 should achieve an appropriate level of operator safety and
avoid unnecessary dispersal of plant protection products into the environment.

Part 2:
Test methods
1 Scope
This part of ISO 19932 specifies test methods for the verification of requirements of ISO/DIS 19932-1
for knapsack sprayers carried on the back or shoulder of the operator for use with plant protection
products.
It is applicable to lever-operated knapsack sprayers, knapsack compression sprayers and knapsack
sprayers driven by an engine or electric motor using hydraulic pressure atomization of the spray liquid
intended to be used primarily in agriculture, forestry and horticulture with a nominal volume of more
than 6,0 l.
It does not apply to knapsack combustion engine-driven air-blast sprayers covered by ISO 28139.
