ISO/DIS 17954-1
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)
3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
International Standard ISO 17954-1 was prepared by Technical Committee ISO/TC Tractors and machinery for
agriculture and forestry 2, Common tests.

Agricultural machine operator enclosures — Air filtration — Part 1:
Definitions, test methods, requirements and information to be provided to
the operator
1 Scope
The scope of this international standard is limited to terminology, definitions, performance criteria, test criteria and
information to be provided to the operator on agricultural operator enclosures on machines used in applying or
exposed to agricultural pesticides excluding fumigants. The purpose is to provide protection inside the operator
enclosure equivalent to that of personal protective equipment (PPE) specified in the use instructions on the
pesticide label, thus eliminating the need to wear PPE respirators when inside the operator enclosure. This
standard provides uniform means to meet the varying regional filtering requirements.
2 Normative reference(s)
The following standards contain provisions, which, through reference in this text, constitute provisions of this
Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
parties to agreements based on this Standard should apply the most recent editions of the standards indicated
below. Standards organizations maintain registers of currently valid standards.

question.
3.3
