FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61310-1 has been prepared by IEC technical committee 44: Safety
of machinery – Electrotechnical aspects.
This second edition cancels and replaces the first edition published in 1995 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous

INTRODUCTION
This standard should be used by suppliers of machines for which no product family or
dedicated product standard exists. The requirements of this standard should also be used, for
example, as a reference standard by ISO and IEC technical committees which prepare
product family or dedicated product standards for machines. Where a product family or
dedicated product standard exists, its requirements take precedence.
At human-machine interfaces, warning and danger signals need to convey safety-related
meanings for the safe use and monitoring of machinery for exposed persons and operators.
It is via the human-machine interface that the operator interacts with the machinery or
process in an open-loop system (see Figure 1). This interface consists of actuators, by
means of which the operator initiates actions, and indicating devices, through which the
operator receives information. In many applications, the information is represented by a
signal which is encoded by a distinct set of rules and the operator has then to interpret the
signal according to these rules. Different types of coding such as colour, shape or time are
used as appropriate to the demands of the task of the operator.
The reasons for using codes are:
– to permit the spatial separation of the machinery from centralized control stations;
– to increase the perceptible amount of information given by an indicating device, for
example, per display area unit, per unit of time;
– to decrease the mental work-load of an operator and/or exposed persons.

SAFETY OF MACHINERY –
INDICATION, MARKING AND ACTUATION –

Part 1: Requirements for visual, acoustic
and tactile signals



1 Scope
This part of IEC 61310 specifies requirements for visual, acoustic and tactile methods of
indicating safety-related information, at the human-machine interface and to exposed persons.
It specifies a system of colours, safety signs, markings and other warnings, intended for use
in the indication of hazardous situations and health hazards and for meeting certain
emergencies. It also specifies ways of coding visual, acoustic and tactile signals for indicators
and actuators to facilitate the safe use and monitoring of the machinery.
This standard is based on IEC 60073 with regard to coding by colour and alternative means,
but is not limited to electrotechnical aspects.

4 Presentation of safety-related information
4.1 General
To reduce the risks to which persons may be exposed,
– machinery shall be fitted with means of giving signals which provide appropriate safety-
related information;

---------------------- Page: 14 ----------------------

61310-1 © IEC:2007 – 19 –
– actuators shall be capable of being used safely, and shall be clearly identified with
appropriate markings on or near the actuator;
– machine manufacturer shall provide means in order to check the operation of warning
signals by the operator.
Active signals shall be provided to signal a hazard and to call persons to take a specific
course of action.
Passive signals shall be provided to warn of permanent risk and to give information, for
example, on the location of escape routes, emergency stop actuators.
NOTE 1 Examples of active and passive signals are given in Table 1.
All safety-related signals shall be so designed that their meaning is clearly and
unambiguously evident to the operator. Ergonomic principles shall be taken into account
especially in the design and installation of the machine. To this end, such signals and their
associated coding shall be applied consistently throughout the machinery. The selection of
equipment to be used shall take into account the consequences of failure of that equipment
(for example, lamp filament, colour gun in a video display unit (VDU) giving rise to a loss of
signal).
NOTE 2 The measures taken should be determined from the risk assessment.
Safety-related information shall be presented using means which are compatible with the
capabilities of the operators and/or exposed persons. Where possible, visual signals shall be
used. Where it is probable that people with sensory deficiencies, for example, blindness,
colour blindness, deafness, or those arising from the use of personal protective equipment,
need to perceive safety-related signals, particular attention shall be paid to ensure this is
addressed by supplementary means, such as the following:
– use of more than one sense (sight, hearing, touch);
– use of multiple coding (see 5.2.2).
Supplementary means to visual signals shall be selected and used in situations where
a) an excess of other information could cause the signal to be not easily perceived;
b) visual signals alone are insufficient because
– the operator needs to look elsewhere while handling/actuating controls;
– exposed persons are out of sight of the operator;
– exposed persons cannot see the warning signals.
