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/IEC 11553-3 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee
SC 9, Electro-optical systems, in collaboration with IEC/TC 76, Optical radiation safety and laser equipment.
ISO/IEC 11553 consists of the following parts, under the general title Safety of machinery — Laser
processing machines:
— Part 1: General safety requirements
— Part 2: Safety requirements for hand-held laser processing devices
— Part 3: Noise reduction and noise measurement methods for laser processing machines and hand-held
processing devices and associated auxiliary equipment (accuracy grade 2)

Introduction
The Machinery Safety Directive issued by the Council of the EU outlines essential and mandatory
requirements that must be met in order to ensure that machinery is safe. In response, CEN/CENELEC initiated
a programme to produce safety standards for machines and their applications. This part of ISO/IEC 11553
is one in that series. It has been prepared as a harmonized standard to provide a means of conforming with
the essential safety requirements of the Machinery Directive and associated EFTA Regulations.
This document is a type B standard as stated in ISO 12100. The provision of this document may be
supplemented or modified by a type C standard.
For machines which are covered by the scope of a type C standard and which have been designed and
built according to the provision of that standard, the provisions of that type C standard take precedence
over the provisions of this type B standard.
It is applicable to machines using laser radiation to process materials. The purpose of this part of
ISO/IEC 11553 is to prevent injuries to persons by
— listing potential hazards generated by machines containing lasers,
— specifying safety measures and verifications necessary for reducing the risk caused by specific
hazardous conditions,
— providing references to pertinent standards, and
— specifying the information which is to be supplied to the users so that they can establish proper
procedures and precautions.

Safety of machinery — Laser processing machines —
Part 3:
Noise reduction and noise measurement methods for laser
processing machines and hand-held processing devices
and associated auxiliary equipment (accuracy grade 2)
1 Scope
This part of ISO/IEC 11553 describes the requirements to deal with noise hazards and specifies all the
information necessary to carry out efficiently and under standardized conditions the determination,
declaration and verification of airborne noise emission from laser processing machines and hand-held
laser processing devices within the scope of ISO/IEC 11553-1 and ISO/IEC 11553-2. It specifies the
safety requirements relating to noise hazards. It specifies noise measurement methods, installation
and operating conditions to be used for the test, together with the information to be supplied by
manufacturers of such equipment.
This part of ISO/IEC 11553 applies to those laser processing machines and hand-held laser processing
devices included in the scope of ISO/IEC 11553-1 and ISO/IEC 11553-2.
Noise emission characteristics include emission sound pressure levels at work stations and the sound
power level. Declared noise emission values permit comparison of laser processing machines and hand-
held laser processing devices on the market.
The use of this noise test code (see Annex A) ensures the reproducibility of the determination of the
characteristic noise emission values within specific limits. These limits are determined by the accuracy
grade of the noise emission measuring method used. Noise emission measurements specified by this
part of ISO/IEC 11553 meet the requirements of an engineering method (accuracy grade 2).

3 Noise hazards
Noise generated by laser processing machines and hand-held laser processing devices can result in, for
example:
a) permanent hearing loss;
b) tinnitus;
c) tiredness, stress, headaches;
d) other effects such as loss of balance, loss of awareness;
e) interference with speech communication;
f) inability to hear acoustic warning signals.
4 Safety requirements and measures
4.1 General requirements for noise reduction
Noise reduction shall be an integral part of the design process by specifically taking into account the
measures at source as suggested in ISO/TR 11688-1. The success of the applied noise reduction measures
is assessed on the basis of the actual noise emission values according to the noise test code specified
within this part of ISO/IEC 11553 in relation to other laser processing machines of a similar application.
4.2 Noise reduction measures
Appropriate noise reduction measures shall be applied.
Particular considerations can be given to:
a) selecting low noise level pumps rather than enclosing the pumps;
b) releasing of pneumatic energy (To conserve energy, unnecessary releases should be avoided.
Silencers or exhaust filters should be considered.);
c) stabilizing vibrating pipelines by special fastenings to reduce noise created by such movements;
d) the laser power generation noise source by selection of low noise components such as fans or by
resilient mounting or absorber;
e) damping measures to be applied at the cooling and fume exhaust systems;

f) preventing vibration of panels by fitting stiffening strips or noise attenuating materials to reduce
the radiation of noise;
g) placing noise producing component parts away from the operator position whenever practicable;
h) applying full and partial acoustic enclosures inside the guard enclosing the process zone to limit the
radiation of noise generated by the laser process into the environment.
The above list is not exhaustive. Alternative technical measures (that may have identical or improved
efficiency) for noise reduction can be considered.
5 Verification of safety requirements for noise emission reduction and/or pro-
tection measures
Noise emission values shall be measured by utilizing appropriate measurement method(s) and a noise
emission declaration shall be given in the instructions for the user if the emission sound pressure level
measured is higher than 70 dB.
