Automatic electrical controls - Part 2-23: Particular requirements for electrical sensors and sensor elements

IEC 60730-2-23:2025 applies to the safety of electrical, electro-mechanical and electronic sensors including sensing elements and any conditioning circuitry. Sensors covered under the scope of this document serve only to transform an activating quantity into a usable output and do not perform a control operation as defined in IEC 60730-1. This document applies to sensors in so far as defining the reliability and accuracy of their inherent operating characteristics and corresponding response under normal and abnormal conditions within the sensor. Sensors, as defined herein, are used in or as part of an automatic electrical control or as independently mounted devices in connection with controls and control systems. The use of this document for other applications in which sensors are used is possible provided that the appropriate safety is maintained as defined by the end product standard. This document applies to discrete sensors constructed of, but not limited to, conductive, semi-conductive, or substrate, for the detection of activating quantities such as voltage, current, temperature, pressure, humidity, light (e.g. optical), gasoline vapours, and the like.
NOTE 1 Future consideration will be given to other sensor technologies constructed of other materials such as chemical, mechanical and micro-electromechanical systems (MEMS), along with other activating quantities like mass flow, liquid, movement, weight, vibration, or other as needed.
This document applies to sensing element(s) as well as any electronic hardware, software, or other conditioning circuits that are inherent to the sensor and relied upon to reliably transform the input signal into a useable response signal (output) for functional safety purposes. Conditioning circuits that are inseparable from the control for which the sensing element relies upon to perform its desired function are evaluated by the requirements of the relevant control Part 2 standard and/or IEC 60730-1.
NOTE 2 Additional requirements can be also applied by the application standard in which the sensor is used.
Throughout this document, whenever it is indicated that the IEC 60730-1 requirements are applicable, the term "control(s)", is replaced by the term "sensor(s)", and the term "equipment" is replaced by the term "control", as they are used in IEC 60730-1, respectively, unless otherwise specified herein.
This document does not apply to sensors explicitly described in another relevant part 2 of the IEC 60730 series.
NOTE 3 For example, a flame sensor as described in IEC 60730-2-5.

Dispositifs de commande électriques automatiques - Partie 2-23: Exigences particulières pour les capteurs électriques et les éléments sensibles

L'IEC 60730-2-23:2025 s'applique à la sécurité des capteurs électriques, électromécaniques et électroniques, y compris les éléments sensibles et les circuits de conditionnement éventuels. Les capteurs couverts par le domaine d'application du présent document permettent uniquement de transformer une grandeur de manœuvre en sortie utilisable et n'effectuent aucune opération de commande définie dans l'IEC 60730-1. Le présent document s'applique aux capteurs dans la mesure où il définit la fiabilité et l'exactitude de leurs caractéristiques de fonctionnement intrinsèques et leur réponse correspondante dans des conditions normales et anormales à l'intérieur du capteur. Les capteurs définis dans le présent document sont utilisés dans un dispositif de commande électrique automatique ou comme partie de celui-ci, ou comme des dispositifs à montage indépendant connectés à des dispositifs et systèmes de commande. L'application du présent document dans le cadre d'autres utilisations des capteurs est possible sous réserve d'assurer la sécurité adéquate, selon la définition donnée dans la norme du produit final. Le présent document s'applique aux capteurs discrets composés notamment d'un conducteur ou d'un substrat semiconducteur, pour la détection de grandeurs de manœuvre comme la tension, le courant, la température, la pression, l'humidité, la lumière (optique, par exemple), les vapeurs d'essence, etc.
NOTE 1 D'autres technologies de capteurs seront envisagées à l'avenir comme les systèmes chimiques, mécaniques et microélectromécaniques (MEMS) ainsi que d'autres grandeurs de manœuvre comme le débit massique, le liquide, le mouvement, le poids, les vibrations, etc.
Le présent document s'applique à l'élément ou aux éléments sensibles, ainsi qu'aux matériels électroniques, logiciels ou autres circuits de conditionnement qui sont intrinsèques au capteur et qui permettent de transformer de manière fiable le signal d'entrée en un signal de réponse (sortie) utilisable à des fins de sécurité fonctionnelle. Les circuits de conditionnement qui sont inséparables du dispositif de commande sur lequel repose l'élément sensible pour accomplir sa fonction souhaitée sont évalués conformément aux exigences de la Partie 2 applicable au dispositif de commande et/ou de l'IEC 60730-1.
NOTE 2 Des exigences supplémentaires peuvent également s'appliquer au titre de la norme d'application dans laquelle le capteur est utilisé.
Dans l'ensemble du présent document, s'il est indiqué que les exigences de l'IEC 60730-1 s'appliquent, le terme "dispositif(s) de commande" est remplacé par le terme "capteur(s)" et le terme "équipement" est remplacé par le terme "dispositif de commande", lorsque ces termes sont respectivement utilisés dans l'IEC 60730-1, sauf spécification contraire dans le présent document.
Le présent document ne s'applique pas aux capteurs décrits de manière explicite dans une autre partie 2 pertinente de la série IEC 60730.
NOTE 3 Par exemple, un capteur de flamme décrit dans l'IEC 60730-2-5.

Part 2-23: Particular requirements for electrical sensors and
sensing elements
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 t
