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
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions 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 the following
URL: 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.
This second edition of ISO 28139 cancels and replaces ISO 28139:2009 and ISO 10988:2011, which have
been technically revised. The main changes compared to the previous edition are as follows:
— addition of environmental requirements;
— addition of environmental tests;
— exclusion of ergonomics;
— general update to the state of the art.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The structure of safety standards in the field of machinery is as follows:
a) type-A standards (basic standards) giving basic concepts, principles for design, and general aspects
that can be applied to machinery;
b) type-B standards (generic safety standards) dealing with one safety aspect or one type of
safeguards that can be used across a wide range of machinery:
— type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise),
— type-B2 standards on safeguards (e.g. two-hand control devices, interlocking devices, pressure
sensitive devices, guards);
c) type-C standards (machinery safety standards) dealing with detailed safety requirements for a
particular machine or group of machines.
This document is a type-C standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or B
standards, the requirements of this type-C standard take precedence over the requirements of the
other standards for machines that have been designed and built according to the requirements of this
type-C standard.

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 28139 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 of ISO 28139 cancels and replaces ISO 28139:2009 and ISO 10988:2011 Equipment
for crop protection -- Knapsack motorized air-assisted sprayers -- Test methods and performance limits,
which has been technically revised

DRAFT INTERNATIONAL STANDARD ISO/DIS 28139:2017(E)
Equipment for crop protection — Knapsack combustion
engine-driven air-blast sprayers — Safety and
environmental requirements and test methods
1 Scope
This International Standard specifies safety requirements and their verification, environmental
requirements and related test methods and minimum performance limits, for the design and
construction of knapsack combustion engine-driven air-blast sprayers as defined in ISO 5681.
NOTE 1 ISO 5681 is currently under revision.
NOTE 2 An example of this machine is given in Annex D.
It describes methods for the elimination or reduction of hazards arising from their use. In addition, it
specifies the type of information on safe working practices to be provided by the manufacturer.
It addresses general operating parameters as well as the potential deposition of spray droplets under
specified controlled conditions.
This International Standard deals with all significant hazards, hazardous situations and events,
excepting those arising from vibration transmitted at the back of operator.
It is applicable to knapsack combustion engine-driven air-blast sprayers when they are used as intended
and under the conditions foreseen by the manufacturer (see Table A.1).
It is not applicable to:
— hydraulic pressure sprayers,
— thermal sprayers,
— cold foggers,
— sprayers adapted for the application of dry material.
It is not applicable to knapsack combustion engine-driven air-blast sprayers manufactured before the
date of its publication.

NOTE to be reviewed during DIS stage. Note 2 to entry: in some Regions the specified limit could be
exceeded.
Wearing parts (such as nozzles, filters, anti-drip valves, valves, diaphragms) specified in the instruction
handbook shall be changeable without special tools, unless provided with the sprayer, by an operator
wearing appropriate protective gloves and without contamination of the operator and the environment.
Compliance shall be checked by inspection and function test.
