Industrial-process measurement, control and automation - Evaluation of system properties for the purpose of system assessment - Part 7: Assessment of system safety

The treatment of safety in this standard is confined to hazards that can be present within the industrial-process measurement and control system itself. Considerations of hazards that can be introduced by the process or equipment under control of the industrial-process measurement and control system to be assessed are excluded. If the system mission includes activities which could affect the safety of the process or equipment under control, the requirements of these activities are the subject of IEC 61508.

L'IEC 61069-7:2016 spécifie la méthode d'évaluation détaillée de la sécurité d'un système faisant partie d'un système de commande de base (BCS) qui repose sur les principes de base de l'IEC 61069-1 et la méthodologie de l'IEC 61069-2; définit la classification de base de la sécurité d'un système; décrit les facteurs ayant une influence sur la sécurité d'un système et dont il faut tenir compte lors de l'appréciation de la sécurité d'un système; et donne des lignes directrices concernant les techniques de sélection à partir d'un ensemble d'options (avec références) pour l'appréciation de la sécurité d'un système. Cette deuxième édition annule et remplace la première édition parue en 1998. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - réorganisation des informations contenues dans l'IEC 61069-7:1998 visant à mieux organiser l'ensemble complet de normes et à le rendre plus cohérent; - l'IEC TS 62603-1 a été incorporée dans cette édition.

Meritve, krmiljenje in avtomatizacija v industrijskih procesih - Ocenjevanje lastnosti sistema zaradi njegovega vrednotenja - 7. del: Vrednotenje sistema za varnost tveganja (IEC 61069-7:2016)

Obravnavanje varnosti v tem standardu je omejeno na nevarnosti, ki so lahko prisotne pri meritvah in krmiljenju v industrijskih procesih. Izključeno je upoštevanje nevarnosti, ki se lahko pojavijo zaradi postopka ali opreme, ki je pod nadzorom meritev in krmiljenja v industrijskih procesih, ki bodo ovrednoteni. Če misija sistema vključuje dejavnosti, ki bi lahko vplivale na varnost krmiljenega procesa ali opreme, so zahteve teh dejavnosti predmet standarda IEC 61508.

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 whic
