IEC 60947-5-3:2026 provides additional requirements to those given in IEC 60947-5-2 and IEC 60947-5-1:2024, Annex D (reed contact magnetic switches). 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 document does not apply to protective equipment to directly detect the presence of persons, that are covered by the IEC 61496 series or IEC TS 62998 series. NOTE 1 A PDDB device can be used to detect indirectly the presence of a person, for example by detecting the position of a platform on which the operator stands (example, garbage trucks). This document does not specify requirements for the analogue output of PDDB, if any. This document does not deal with any specific requirements on acoustic noise as the noise emission of proximity devices is not considered to be a relevant hazard. A PDDB product is intended to be used as sensing subsystem of a safety related control system according to IEC 62061 or ISO 13849-1. Depending on construction principles and complexity, this document is based on product development of the IEC 61508 series to meet the product specific requirements of one or more of the following: – IEC 61508 series; – IEC 62061; – ISO 13849 series. NOTE 2 The Functional safety device type classification regarding functional safety correlates with IEC 62683-2-3. This document includes requirements for PDDB when designed for use as part of an interlocking device according to ISO 14119. This document does not consider aspects of: – software updates and self-evolving behaviour; – explosive atmospheres. This third edition cancels and replaces the second edition published in 2013. This edition constitutes a technical revision. This third edition includes the following significant technical changes with respect to the previous edition: a) Update of the scope, refined fault performance aspects and relation to standards of functional safety. b) The ‘safe state’ is generally determined as ‘OFF-state’ (see 3.1.8). c) Update of EMC requirements in 8.2.6 with references to IEC 60947-5-2:2019 for acceptance criteria A, B and C and requirements of Table 17 for acceptance criterion DS. d) Interface types for binary interfaces are introduced (see 4.6.2 and Annex B). e) Functional safety device types according to ISO 13849-1:2023 Annex O (see 4.9). f) Interlocking device type and coding level according to ISO 14119 are adapted (see 4.10 and 4.11). g) The operating modes target present (4.12.2) and target absent (4.12.3) are introduced. h) The ‘switching distance’ replaces the terms ‘release’ and ‘operating’. The behaviour of the PDDB is described according to the operating mode (4.12). i) The context and verification of the switching distances are considered according to ISO/IEC Guide 98-3:2008 (GUM) and IEC TR 63649 (see 8.2.1.3 and 9.4.2). j) Requirements for electrical equipment class III are refined. k) The risk time is replaced with the safety response time (3.1.11). l) Annex A gives a new example of safety related control system. m) The test sequences (see 9.3.1) are updated for the specific behaviour of a PDDB. IEC 60947-5-3:2026 fournit des exigences supplementaires a celles enoncees dans lIEC 60947-5-2 et lIEC 60947-5-1:2024, Annexe D (interrupteurs magnetiques a lames souples). Elle couvre les aspects de defaut des dispositifs de detection de proximite a comportement defini (PDDB, Proximity Devices with a Defined Behaviour) dans les conditions de defaut. Elle ne couvre aucune autre fonctionnalite qui peut etre exigee pour des applications specifiques. Le present document ne sapplique pas aux equipements de protection destines a detecter directement la presence de personnes, qui sont couverts par la serie IEC 61496 ou la serie IEC TS 62998. NOTE 1 Un dispositif PDDB peut etre utilise pour detecter indirectement la presence dune personne, par exemple en detectant la position dune plateforme sur laquelle se situe loperateur (camions poubelles, par exemple). Le present document ne specifie pas dexigences relatives a la sortie analogique du PDDB, le cas echeant. Le present document ne traite pas des exigences specifiques concernant le bruit acoustique dans la mesure ou lemission de bruit par les dispositifs de detection de proximite nest pas consideree comme un phenomene dangereux. Un produit PDDB est destine a etre utilise comme sous systeme de detection dun systeme de commande relatif a la securite selon lIEC 62061 ou lISO 13849-1. En fonction des principes de construction et de la complexite, le present document repose sur le developpement de produits de la serie IEC 61508 afin de satisfaire aux exigences specifiques aux produits dune ou de plusieurs des normes suivantes: – serie IEC 61508; – IEC 62061; – serie ISO 13849. NOTE 2 La classification des types de dispositifs de securite fonctionnelle par rapport a la securite fonctionnelle est correlee avec lIEC 62683-2-3. Le present document comporte des exigences relatives aux PDDB lorsquils sont concus pour etre utilises en tant que partie dun dispositif de verrouillage selon lISO 14119. Le present document ne tient pas compte des aspects relatifs: – aux mises a jour logicielles et au comportement autoevolutif; – aux atmospheres explosives. Cette troisieme edition annule et remplace la deuxieme edition parue en 2013. Cette edition constitue une revision technique. Cette troisieme edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) mise a jour du domaine dapplication, precision des aspects de defaut et de la relation avec les normes de securite fonctionnelle; b) l"etat de securite" est generalement determine comme etant l"etat INACTIF" (voir le 3.1.8); c) mise a jour des exigences de CEM au 8.2.6 avec reference a lIEC 60947-5-2:2019 pour les criteres dacceptation A, B et C et aux exigences du Tableau 17
