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.

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.

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.

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 document deals with all significant hazards, hazardous situations and events, excepting those

arising from vibration transmitted to the back of the operator.

It is applicable to knapsack combustion engine-driven airblast sprayers when they are used as intended

and under the conditions foreseeable 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 airblast sprayers manufactured before the

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

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.
