(Main)Safety of machinery - Functional safety of safety-related electrical, electronic and programmable electronic control systems
Safety of machinery - Functional safety of safety-related electrical, electronic and programmable electronic control systems
This International Standard specifies requirements and makes recommendations for the design, integration and validation of safety-related electrical, electronic and programmable electronic control systems (SRECS) for machines (see Notes 1 and 2). It is applicable to control systems used, either singly or in combination, to carry out safety-related control functions on machines that are not portable by hand while working, including a group of machines working together in a co-ordinated manner.

Elle s'applique aux systèmes de commande utilisés, séparément ou en combinaison, pour assurer des fonctions de commande relatives à la sécurité de machines qui ne sont pas portables à la main en fonctionnement, y compris un groupe de machines fonctionnant ensemble d'une manière coordonnée
Varnost strojev – Funkcijska varnost na varnost vezanih električnih, elektronskih in programirljivih elektronskih krmilnih sistemov (IEC 62061:2005)
Ta mednarodni standard določa zahteve in priporočila za izdelavo, vgradnjo in ovrednotenje na varnost vezanih električnih, elektronskih in programirljivih elektronskih krmilnih sistemov (SRECS) za stroje (glej opombi 1 in 2). Uporablja se za krmilne sisteme, ki se samostojno ali v kombinaciji uporabljajo za izvajanje na varnost vezanih krmilnih funkcij na strojih, ki jih med delom ni mogoče prenašati v roki, vključno s skupino strojev, ki delujejo skupaj na usklajen način.

This European Standard was approved by CENELEC on 2004-12-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,

Foreword
The text of document 44/460/FDIS, future edition 1 of IEC 62061, prepared by IEC TC 44, Safety of
machinery - Electrotechnical aspects, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as EN 62061 on 2004-12-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-12-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 98/37/EC. See Annex ZZ.
PROOF TEST INTERVAL AND LIFETIME
The following important information should be noted in relation to the requirements of this standard:
Where the probability of dangerous failure per hour (PFH ) is highly dependent upon proof testing (i.e.
D
tests intended to reveal faults not detected by diagnostic functions) then the proof test interval needs
to be shown as realistic and practicable in the context of the expected use of the safety-related
electrical control system (SRECS) (e.g. proof test intervals of less than 10 years can be unreasonably
short for many machinery applications).
CEN/TC114/WG6 have used a proof test interval (mission time) of 20 years to support the estimation
of mean time to dangerous failure (MTTF ) for the realization of designated architectures in Annex B
D
of prEN ISO 13849-1. Therefore, it is recommended that SRECS designers endeavour to use a 20
year proof test interval.
It is acknowledged that some subsystems and/or subsystem elements (e.g. electro-mechanical
components with high duty cycles) will require replacement within the SRECS proof test interval.
Proof testing involves detailed and comprehensive checks that can, in practice, only be performed
when the SRECS and/or its subsystems has been designed to facilitate proof testing (e.g. dedicated
test ports) and provided with necessary information (e.g. proof test instructions).
