Ta del skupine standardov IEC 60947 zagotavlja dodatne zahteve poleg zahtev iz standarda IEC 60947-5-2. Obravnava vidike v zvezi z okvarami približevalnih naprav z določenim obnašanjem ob okvarnih razmerah (PDDB). Ne obravnava nobenih drugih značilnosti, ki so lahko zahtevane za posebne uporabe. Ta standard ne zajema približevalnih naprav z analognim izhodom. Ta standard ne obravnava posebnih zahtev za akustični šum, saj se emisije hrupa krmilnih naprav in stikalnih elementov ne štejejo za ustrezno tveganje. Za približevalne naprave z določenim obnašanjem, ki se uporabljajo v okviru uporab, pri katerih se zahtevajo dodatne značilnosti, obravnavane v drugih standardih, se uporabljajo zahteve vseh ustreznih standardov. Uporaba izključno tega standarda ne dokazuje primernosti za izvajanje katere koli posebne funkcije, povezane z varnostjo. Ta standard ne zagotavlja zahtev za značilnosti proženja približevalne naprave z določenim obnašanjem ali za način za zmanjšanje učinkov vzajemnih motenj med napravami, npr. kodirani cilji. Zato je treba poleg zahtev tega standarda upoštevati tudi te zahteve in vse druge zahteve, specifične za uporabe.

Overview
EN 60947-5-3:2013 - Low-voltage switchgear and controlgear, Part 5-3 - specifies additional requirements for proximity devices with defined behaviour under fault conditions (PDDB). It complements EN/IEC 60947-5-2 by focusing on the fault performance and safety behaviour of proximity sensors used in control circuits. This edition updates and replaces the 1999 edition (plus 2005 amendment) and aligns PDDB requirements with modern functional safety principles.
Key topics and technical requirements
- Scope and purpose: Defines requirements only for PDDB fault performance; other application‑specific characteristics are outside the scope.
- Definitions and terminology: Comprehensive terms, symbols and architectural constraints for PDDB design and assessment.
- Classification: PDDBs are classified according to functional safety frameworks referenced in the standard, including the IEC 61508 principles and classifications aligned with IEC 62061 and ISO 13849-1.
- Construction and characteristics: Rules for constructional characteristics, specified targets, current-carrying parts, terminals, and marking/identification of devices.
- Product information and documentation: Required markings, identification, and instructions for installation, operation and maintenance.
- Environmental and EMC considerations: Normative references include environmental test standards (IEC 60068 series), degrees of enclosure protection (IEC 60529/IP code) and a range of EMC immunity tests (IEC 61000-4-x series) used to verify robustness.
- Testing and performance under fault conditions: Procedures and expected behaviour of PDDBs when faults occur are addressed so that devices exhibit a defined, predictable response.
- Machine safety linkage: Informative Annex ZZ explains how compliance supports conformity with the Machinery Directive (2006/42/EC) within the standard’s scope.
Applications and who uses this standard
EN 60947-5-3 is essential for:
- Machine designers and OEMs specifying safety sensors and interlocks (guard monitoring, presence detection).
- Safety engineers and functional safety assessors evaluating sensor behaviour under fault conditions and ensuring compliance with safety standards.
- Sensor and controlgear manufacturers developing PDDB-class proximity devices and preparing product documentation and tests.
- Certification bodies and notified bodies verifying conformity to European machinery safety requirements.
Typical applications include safety interlocks, protective guards, access control on automated machinery and any safety‑related control circuit requiring predictable sensor failure behaviour.

Requirements for proximity devices with defined
behaviour under fault conditions (PDDB)
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 60947-5-3 has been prepared by subcommittee 17B: Low-voltage
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
This second edition replaces the first edition published in 1999 and its amendment published
in 2005. It is a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) general principles of IEC 61508 series;
b) classification according to the requirements of IEC 62061;
c) classification according to ISO 13849-1.
This standard is to be read in conjunction with IEC 60947-1, Low voltage switchgear and
controlgear – Part 1: General rules and IEC 60947-5-2, Low-voltage switchgear and
60947-5-3 © IEC:2013 – 5 –
controlgear – Part 5-2: Control circuit devices and switching elements – Proximity switches.
The provisions of Part 1 and Part 5-2 are only applicable to this standard where specifically
called for. The numbering of the subclauses of this standard is sometimes not continuous
because it is based on the numbering of the subclauses of IEC 60947-1 or IEC 60947-5-2.
The text of this standard is based on the following documents:
FDIS Report on voting
17B/1821/FDIS 17B/1826/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60947 series, published under the general title Low-voltage
switchgear and controlgear, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR –
Part 5-3: Control circuit devices and switching elements –
Requirements for proximity devices with defined
behaviour under fault conditions (PDDB)
1 General
1.1 Scope
This part of IEC 60947 series provides additional requirements to those given in IEC 60947-5-
2. It addresses the fault performance aspects of proximity devices with a defined behaviour
under fault conditions (PDDB). It does not address any other characteristics that can be
required for specific applications.
This standard does not cover proximity devices with analogue output.
This Standard does not deal with any specific requirements on acoustic noise as the noise
emission of control circuit devices and switching elements is not considered to be a relevant
hazard.
For a PDDB used in applications where additional characteristics, dealt with in other
standards, are required, the requirements of all relevant standards apply.
The use of this standard alone does not demonstrate suitability for the implementation of any
specific safety related functionality. In particular, this standard does not provide requirements
for the actuation characteristics of a PDDB, or for means to reduce the effects of mutual
interference between devices, e.g. coded targets. Therefore these and any other application-
specific requirements will need to be considered in addition to the requirements of this
standard.
NOTE 1 Due to their behaviour under fault conditions, PDDBs can, for example, be used as interlocking devices
(see ISO 14119).
NOTE 2 The requirements for electro-sensitive protective equipment for the detection of persons are given in the
IEC 61496 series.
1.2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.
