Acoustics - Noise emitted by machinery and equipment - Guidelines for the use of basic standards for the determination of emission sound pressure levels at a work station and at other specified positions (ISO 11200:2014)
EN ISO 11200 is the frame standard introducing the basic group, ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205, on the determination of emission sound pressure levels at work stations and other specified positions. It gives guidance for: - facilitating the writing of noise test codes; - providing physical explanations of this noise emission quantity compared to other noise quantities (see 4.1 to 4.3); - comparing the different measurement methods offered by the group (see Table 1); - facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6). This International Standard is largely based on flow charts and tables. Case studies are described. The guidance given applies to airborne sound only. It is for use in noise testing, in general, and in the preparation of noise test codes, in particular. A standardized noise test code is intended to select standards from the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group, which are the most appropriate to the machinery family it covers, and which give detailed requirements on mounting and operating conditions for the particular family, as well as the location of the work station(s) and other specified positions as prescribed in these International Standards. The data so obtained can be used for the declaration and verification of emission sound pressure levels, e.g. as specified in ISO 4871.

ISO 11200:2014(E)
Introduction
0.1 For many users of machinery and equipment, the control of noise is a major issue which requires
effective exchange of acoustical information among the several parties concerned. These include the
manufacturer, installer and user of the machinery or equipment. This acoustical information is obtained
from measurements. The main flow of information goes from the manufacturer to the user.
These measurements are useful only if the conditions under which they are carried out are specified,
if they yield defined acoustical quantities, and if they are carried out using standardized instruments.
Two quantities which complement one another can be used to describe the sound emission of machinery
or equipment: the sound power level and the emission sound pressure level at a specified position. The
International Standards which describe the basic methods of determining the sound power level are
[2]
ISO 3740, ISO 3741, ISO 3743 (all parts), ISO 3744, ISO 3745, ISO 3746 and ISO 3747 (determination from
sound pressure level measurements), and ISO 9614-1, ISO 9614-2 and ISO 9614-3 (determination from
sound intensity measurements). This International Standard introduces a group of five International
Standards describing various methods for determining emission sound pressure levels of machinery
and equipment taking into account possible situations for the source under test (mobile machine, fixed
machine, various test rooms, various instrumentations, different kinds of work stations, etc.).
It is not the intention of this group of International Standards to describe procedures for measuring the
[4]
occupational noise exposure of workers; for occupational noise exposure, see ISO 9612.
0.2 Emission sound pressure levels in conjunction with sound power levels are used for declaration
of the noise emitted under the defined conditions, verification of declared values, comparison of the
noise emitted by machinery of various types and sizes, comparison with limits specified in a purchasing
contract or a regulation, engineering work to reduce the noise emission of machinery, and prediction of
noise exposure at the specified positions.
Included in this group of International Standards are three, which describe procedures for measuring
emission sound pressure levels directly, in different test environments (ISO 11201, ISO 11202 and
ISO 11204), a fourth (ISO 11203), which gives procedures for determining emission sound pressure
levels from the sound power level and a fifth (ISO 11205), which gives a procedure for determining the
emission sound pressure level from measured values of the sound intensity level.
0.3 In general, these sound pressure levels are different from those which occur if the machinery or
equipment operates in its installed surroundings, where the environment influences the sound pressure
level at work stations or other specified positions. The selection of standards for the determination of
the sound power level can, for practical reasons, have consequences on the selection of standards for
the determination of the emission sound pressure level. It is preferable to make the choice of standards
concurrently with respect to the two noise emission quantities.
0.4 Standards in the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group are often used
in practice through their reference in standardized noise test codes (see 3.25). If a particular noise test
code exists for a family of machinery, it is intended that it be used. For drafting a noise test code, it is
[6]
recommended to be familiar with ISO 12001.
0.5 The reasons for revising the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 group were
manifold:
— the need arose to introduce a grade 1 method into the group in order to enhance the similarity with
the ISO 3741, ISO 3743 (all parts), ISO 3744, ISO 3745, ISO 3746 and ISO 3747 group of International
Standards on the determination of sound power level;
— feedback from experience with the use of the group showed that the ISO 11202 method gave more
precise results than initially thought, hence the introduction into ISO 11202 of the possibility to get
grade 2 results;
— as source directivity plays a key role with regard to the emission sound pressure level, pragmatism
led to introduce this parameter into the ISO 11202 and ISO 11204 methods;
© ISO 2014 – All rights reserved v
---------------------- Page: 11 ----------------------
SIST EN ISO 11200:2014
ISO 11200:2014(E)
— as measurement uncertainty was becoming a more and more central issue, the need arose to address
the issue again in the light of the experience gained with the use of ISO/IEC GUIDE 98-3.
No research was carried out in order to revise the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and
ISO 11205 group. Only existing knowledge was used.

INTERNATIONAL STANDARD ISO 11200:2014(E)
Acoustics — Noise emitted by machinery and equipment
— Guidelines for the use of basic standards for the
determination of emission sound pressure levels at a work
station and at other specified positions
1 Scope
This International Standard is the frame standard introducing the basic group, ISO 11201, ISO 11202,
ISO 11203, ISO 11204 and ISO 11205, on the determination of emission sound pressure levels at work
stations and other specified positions. It gives guidance for:
— facilitating the writing of noise test codes;
— providing physical explanations of this noise emission quantity compared to other noise
quantities (see 4.1 to 4.3);
— comparing the different measurement methods offered by the group (see Table 1);
— facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6).
This International Standard is largely based on flow charts and tables. Case studies are described.
The guidance given applies to airborne sound only. It is for use in noise testing, in general, and in the
preparation of noise test codes, in particular.
A standardized noise test code is intended to select standards from the ISO 11201, ISO 11202, ISO 11203,
ISO 11204 and ISO 11205 group, which are the most appropriate to the machinery family it covers, and
which give detailed requirements on mounting and operating conditions for the particular family, as well
as the location of the work station(s) and other specified positions as prescribed in these International
Standards.
The data so obtained can be used for the declaration and verification of emission sound pressure levels,
[3]
e.g. as specified in ISO 4871.

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 11200 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise.
This second edition cancels and replaces the first edition (ISO 11200:1995), which has been technically
revised.

ISO/DIS 11200
Introduction
0.1 For many users of machinery and equipment the control of noise is a major issue which requires
effective exchange of acoustical information among the several parties concerned. These include the
manufacturer, installer and user of the machinery or equipment. This acoustical information is obtained from
measurements. The main flow of information goes from the manufacturer to the user.
These measurements are useful only if the conditions under which they are carried out are specified, if they
yield defined acoustical quantities, and if they are made using standardized instruments.
Two quantities which complement one another can be used to describe the sound emission of machinery or
equipment: the sound power level and the emission sound pressure level at a specified position. The
International Standards which describe the basic methods of determining the sound power level are ISO 3740
to ISO 3747 (determination from sound pressure level measurements) and ISO 9614-1 to ISO 9614-3
(determination from sound intensity measurements). This International Standard introduces a series of five
International Standards describing various methods for determining emission sound pressure levels of
machinery and equipment taking into account possible situations for the source under test (mobile machine,
fixed machine, various test rooms, various instrumentations, different kinds of operator positions, etc.).
It is not the intent of this series of International Standards to describe procedures for measuring the
occupational noise exposure of workers: see ISO 9612.
0.2 Emission sound pressure levels in conjunction with sound power levels are used for declaration of the
noise emitted under the defined conditions, verification of declared values, comparison of the noise emitted by
machinery of various types and sizes, comparison with limits specified in a purchasing contract or a
regulation, engineering work to reduce the noise emission of machinery, and prediction of noise exposure at
the specified positions.
Included in this series of International Standards are three which describe procedures for measuring emission
sound pressure levels directly, in different test environments (ISO 11201, ISO 11202 and ISO 11204), a fourth
(ISO 11203) which gives procedures for determining emission sound pressure levels from the sound power
level and a fifth (ISO 11205) which gives a procedure for determining the emission sound pressure level from
measured values of the intensity level.
0.3 In general, these sound pressure levels are different from those that occur if the machinery or
equipment operates in its installed surroundings, where the environment influences the sound pressure level
at work stations or other specified positions. The selection of standards for the determination of the sound
power level can, for practical reasons, have consequences on the selection of standards for the determination
of the emission sound pressure level. It is preferable to make the choice of standards concurrently with
respect to the two noise emission quantities.
0.4 For a particular family of machinery or equipment, noise test codes specify the method to be used for
the determination of the sound power, the method to be used for the determination of emission sound
pressure levels at work stations, and at other specified positions, the positions of the work stations, the
mounting and operating conditions of the machine under test for the purpose of determining the noise
emission quantities, the method to be used for verifying declared noise emission quantities. For drafting a
noise test code, it is recommended to be familiar with ISO 3744.
0.5 The reasons for revising the series ISO 11201 to ISO 11205 were manifold:
⎯ the need arose to introduce a Grade 1 method into the series in order to enhance the similarity with the
ISO 3740 series of standards on the determination of sound power level;
© ISO 2012 – All rights reserved v
---------------------- Page: 11 ----------------------
oSIST prEN ISO 11200:2012
ISO/DIS 11200
⎯ feedback from experience with the use of the series showed that the ISO 11202 method gave more
precise results than initially thought, hence the introduction into ISO 11202 of the possibility to get
Grade 2 results;
⎯ as source directivity plays a key role with regard to the emission sound pressure level, pragmatism led to
introduce this parameter into the ISO 11202 and ISO 11204 methods;
⎯ as measurement uncertainty was becoming a more and more central issue, the need arose to address
the issue again in the light of the experience gained with the use of the ISO/IEC GUIDE 98-3.
No research was carried out in order to revise the series ISO 11201 to ISO 11205. Only existing knowledge
was used.

DRAFT INTERNATIONAL STANDARD ISO/DIS 11200
Acoustics — Noise emitted by machinery and equipment —
Guidelines for the use of basic standards for the determination
of emission sound pressure levels at a work station and at other
specified positions
1 Scope
This International Standard is the frame standard introducing the series ISO 11201 to ISO 11205 of basic
International Standards on the determination of emission sound pressure levels at work stations and other
specified positions (ISO 11201 to ISO 11205). It is a guide aiming at:
⎯ facilitating the writing of noise test codes;
⎯ providing physical explanations on this noise emission quantity as compared to other noise
quantities (4.1 to 4.3);
⎯ comparing the different measurement methods offered by the series (Clause 5, Table 1);
⎯ facilitating the choice of the most appropriate method(s) in typical practical situations (Clause 6).
This International Standard is largely based on flow-charts and tables. Case studies are described.
The guidance given applies only to airborne sound. It is for use in noise testing in general and in the
preparation of noise test codes, in particular.
A standardized noise test code should select standards in the series ISO 11201 to ISO 11205 that are the
most appropriate to the machinery family it covers, give detailed requirements on mounting and operating
conditions for the particular family, as well as the location of the work station(s) and other specified positions
as prescribed in these International Standards.
The data so obtained may be used for the declaration and verification of emission sound pressure levels e.g.
as specified in ISO 4871.

NOTE Equation (4) is equivalent to that for the environmental noise descriptor “sound exposure level”. However, the
emission quantity defined above is used to characterize the noise emitted by a source under test and assumes that
standardized measurement, mounting, and operating conditions as well as a controlled acoustical environment are used
for the measurements.
