Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 8902 was prepared by Technical Committee ISO/TC 54,
Essential oils.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.

IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies).
The work of preparing International Standards is normally carried out through IS0 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 committie.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
I
The main task of IS0 technical committees is to prepare International Standards. In exceptional circumstances a technical commitlee
may propose the publication of a technical report of one of the following types :
I
- type 1, when the necessary support within the technical committee cannot be obtained for the publication of an International
Standard, despite repeated efforts;
- type 2, when the subject is still under technical development requiring wider exposure;
-
type 3, when a technical committee has collected data of a different kind from that which is normally published as lan
International Standard ("state of the art", for example).
~
Technical reports are accepted for publication directly by IS0 Council. Technical reports types 1 and 2 are subject to review wit$n
three years of publication, to decide if they can be transformed into International Standards. Technical reports type 3 do riot
necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.
ISO/TR 89% was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry.
The reasons which led to the decision to publish this document in the form of a technical report type 1 are explained in the

O Introduction
0.1 This document is issued as a Technical Report because it possesses the following limitations to being regarded as an Inter-
national Standard; agreement could not therefore be reached for its publication as a Standard.
a) Reproducible results can be anticipated only when the ambient environment is controlled. This is possible with tractors which
may be fully enclosed in environmental chambers during testing, but may not be possible for machines, such as combine
harvesters, which are too large for most environmental chambers. There is therefore a need to conduct the tests in uncontrolled
environments (such as under a canopy for large machines).
b) The method specifies engine loading. Although this is necessary for tractors where engine and transmission heating will affect
cab heat load, it may not be necessary for combine harvesters.
c) Although a loaded engine test compensates for solar heat load in a tractor test, no such compensation is possible in tests on a
combine harvester.
There was general agreement that more information and experience is needed before an International Standard can be established. It
was also agreed however that publication as a Technical Report would be useful in outlining an accepted preferred test method for air-
conditioning systems.
0.2 The purpose of this Technical Report is to establish, for tractors and self-propelled machines for agriculture and forestry, a
uniform test method to measure the contribution to operator environmental temperature and humidity provided by an air-conditioning
system operating in a specified ambient environment. The method does not determine the complete climatic environment of the
operator since this is also affected by heat radiation from sources other than those on the machine, for example solar radiation.
1 Scope and field of application
This Technical Report specifies a test method to evaluate the performance of air-conditioning systems on tractors and self-propelled
machines for agriculture and forestry.
NOTE - The term ”vehicle” in this Report refers to tractors and self-propelled machines for agriculture and forestry and is used for editorial clarity
and conciseness.
The term ”air-conditioning system” refers to any electromechanical refrigeration system intended to reduce air temperatures in the operator’s
enclosure.
This recommended procedure can be used to evaluate any air-conditioning system; it does not apply to ventilating systems using
ambient temperature air.
