Introduction
The Machinery Safety Directive issued by the European Parliament and the Council of the EC 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 document is one in that series.
It has been prepared as a harmonized standard to provide a means of conforming to 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 provisions 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.
The purpose of this document is to prevent injuries to persons by
— listing potential laser radiation 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.

Introduction
The Machinery Safety Directive issued by the European Parliament and the Council of the EC 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 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 provisions 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 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.

oSIST prEN ISO 11553-1:2017
ISO DIS 11553-1:2016(E)
To satisfy these requirements, the following condition shall be met: Unauthorized human access to a
hazard area shall be prevented by engineering measures as stipulated in IEC 60825-1 and ISO 12100.
NOTE Most commonly with an enclosure as described in IEC 60825-4.
5.3.2.1.2 Restricted or controlled access
For laser processing machines operating in locations with restricted or controlled access, the possibility
that people be exposed to levels of laser radiation exceeding the maximum permissible exposure (MPE)
4
at the ocular exposure limits for 31× 0 seconds exposure shall be eliminated during production
(normal or otherwise).
To satisfy this requirement, the following conditions shall be met:
a) A Risk Assessment shall be performed. Unauthorized human access to a hazard area should be
prevented by engineering measures as specified in IEC 60825-1 and ISO 12100;
b) If access cannot be prevented, exposure above the ocular MPE shall be eliminated by use of
engineering or administrative controls, including Personal Protective Equipment (PPE).
5.3.2.1.3 Without regard to restricted or controlled access
For all laser processing machines, without regard to restricted or controlled access, the following
shall apply.
a) If human presence in a hazard area is unavoidable while the machine is functioning (e.g. during
service), the machine shall be equipped with means for direct control (e.g. enabling switch, two
hand control element) of machine motion, beam direction and beam isolation (see 5.3.3.5).
b) The design of protective devices, such as switches, shutters, guards, beam dissipation devices
and deterring/impeding devices, shall meet the requirements specified in IEC 60825-1 and
ISO 12100. A single protective device may be used to provide simultaneous protection against
more than one hazard.
c) Protective housings are not subject to IEC 60825-4, Annex D, but shall otherwise conform to
IEC 60825-4. Purchased Laser guards (not part of a protective housing) shall comply with
requirements specified in IEC 60825-4, Annex D.
d) If human access to a part of a beam delivery system is possible when the machine is functioning
(e. g. for a machine using a laser device installed external to the guards), the interface between the
laser device and the beam delivery system shall comply to the following requirements.
1) The interface shall be designed so that the beam delivery system and laser device match with
respect to:
— optical elements;
— mechanical elements.
2) Any beam delivery system shall require a tool for disconnection or be interlocked to prevent
access to hazardous laser radiation. The laser device shall be switched off prior to any laser
radiation emission from the disconnected interface. Appropriate technical measures shall
ensure that no laser radiation is emitted from a fibre beam delivery system outside the process
zone (e.g. fibre monitoring).
Whenever and wherever there are multiple laser sources (e.g. from a back-up laser, energy share
multiplex (beam split) or time share multiplex (beam switch) the safety controls for each respective
work station, process zone or hazard area shall be automatically connected or associated with each
respective laser source, such that when that station’s interlocks or Emergency Stops or other protective
device sensors are activated, no hazardous laser energy can be directed to that station or zone.
