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 10218-1 was prepared by Technical Committee ISO/TC 184, Automation systems and integration,
Subcommittee SC 2, Robots and robotic devices.
This second edition cancels and replaces the first edition (ISO 10218-1:2006), which has been technically
revised. It also incorporates Technical Corrigendum ISO 10218-1:2006/Cor.1:2007.
ISO 10218 consists of the following parts, under the general title Robots and robotic devices — Safety
requirements for industrial robots:

ISO 10218-1:2011(E)
Introduction
ISO 10218 has been created in recognition of the particular hazards that are presented by industrial robots
and industrial robot systems.
This part of ISO 10218 is a type-C standard as outlined in ISO 12100.
When provisions of a type-C standard are different from those which are stated in type-A or type-B standards,
the provisions of the type-C standard take precedence over the provisions of the other standards for machines
that have been designed and built in accordance with the provisions of the type-C standard.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the Scope of this part of ISO 10218.
Hazards associated with robots are well recognized, but the sources of the hazards are frequently unique to a
particular robot system. The number and type(s) of hazard(s) are directly related to the nature of the
automation process and the complexity of the installation. The risks associated with these hazards vary with
the type of robot used and its purpose, and the way in which it is installed, programmed, operated and
maintained.
Not all of the hazards identified by ISO 10218 apply to every robot, nor will the level of risk associated with a
NOTE
given hazardous situation be the same from robot to robot. Consequently, the safety requirements, or the protective
measures, or both, can vary from what is specified in ISO 10218. A risk assessment can be conducted to determine what
the protective measures should be.
In recognition of the variable nature of hazards with different uses of industrial robots, ISO 10218 is divided
into two parts. This part of ISO 10218 provides guidance for the assurance of safety in the design and
construction of the robot. Since safety in the application of industrial robots is influenced by the design and
application of the particular robot system integration, ISO 10218-2 provides guidelines for the safeguarding of
personnel during robot integration, installation, functional testing, programming, operation, maintenance and
repair.
This part of ISO 10218 has been updated based on experience gained in developing the ISO 10218-2
guidance on system and integration requirements, in order to ensure it remains in line with minimum
requirements of a harmonized type-C standard for industrial robots. Revised technical requirements include,
but are not limited to, definition and requirements for singularity, safeguarding of transmission hazards, power
loss requirements, safety-related control circuit performance, addition of a category 2 stopping function, mode
selection, power and force limiting requirements, marking, and updated stopping time and distance metric and
features.
This part of ISO 10218 is not applicable to robots that were manufactured prior to its publication date.

INTERNATIONAL STANDARD
ISO 10218-1:2011(E)
Robots and robotic devices — Safety requirements for
industrial robots —
Part 1:
Robots
1 Scope
This part of ISO 10218 specifies requirements and guidelines for the inherent safe design, protective
measures and information for use of industrial robots. It describes basic hazards associated with robots and
provides requirements to eliminate, or adequately reduce, the risks associated with these hazards.
This part of ISO 10218 does not address the robot as a complete machine. Noise emission is generally not
considered a significant hazard of the robot alone, and consequently noise is excluded from the scope of this
part of ISO 10218.
This part of ISO 10218 does not apply to non-industrial robots, although the safety principles established in
ISO 10218 can be utilized for these other robots.
NOTE 1
Examples of non-industrial robot applications include, but are not limited to, undersea, military and space
robots, tele-operated manipulators, prosthetics and other aids for the physically impaired, micro-robots (displacement less
than 1 mm), surgery or healthcare, and service or consumer products.
NOTE 2 Requirements for robot systems, integration, and installation are covered in ISO 10218-2.
NOTE 3
system-related hazards need to be considered during robot design.
Additional hazards can be created by specific applications (e.g. welding, laser cutting, machining). These
