ISO 13850:2006(E)
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 13850 was prepared by Technical Committee ISO/TC 199, Safety of machinery, and Technical
Committee IEC/TC 44, Safety of machinery — Electrotechnical aspects.
This second edition cancels and replaces the first edition (ISO 13850:1996), which has been technically
revised. Notably, it incorporates the following significant changes:
a) resetting of the emergency stop command is required to be manual (see 4.1.6);
b) emergency stop devices are required to use mechanical latching (see 4.4.3).
ISO 13850:2006(E)
Introduction
The structure of safety standards in the field of machinery is as follows.
a) Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that
can be applied to machinery.
b) Type-B standards (generic safety standards) deal with one or more safety aspect(s) or one or more
type(s) of safeguard that can be used across a wide range of machinery:
⎯ type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
⎯ type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive
devices, guards).
c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular
machine or group of machines.
This International Standard is a type-B2 standard as stated in ISO 12100-1.
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 according to the provisions of the type-C standard.

INTERNATIONAL STANDARD ISO 13850:2006(E)

Safety of machinery — Emergency stop — Principles for design
1 Scope
This International Standard specifies functional requirements and design principles for the emergency stop
function on machinery, independent of the type of energy used to control the function.
It is applicable to all machinery except for:
⎯ machines in which the provision of emergency stop would not lessen the risk;
⎯ hand-held portable machines and hand-guided machines.
It does not deal with functions such as reversal or limitation of motion, deflection, shielding, braking or
disconnecting, which can be part of the emergency stop function.
