Annotation of standard text IEC 60987-ed.3.0 :
IEC 60987:2021 provides requirements and recommendations for the hardware aspects of I&C systems whatever the technology and applies for all safety classes in a graded manner (as defined by IEC 61513). The requirements defined within this document guide, in particular, the selection of pre-existing components, hardware aspects of system detailed design and implementation and equipment manufacturing. This third edition cancels and replaces the second edition published in 2007. This edition includes the following significant technical changes with respect to the previous edition: a) Title modified; b) Take account of the fact that hardware requirements apply to all I&C technologies, including conventional hardwired equipment, programmable digital equipment or by using a combination of both types of equipment; c) Align the standard with the new revisions of IAEA documents SSR-2/1, which include as far as possible an adaptation of the definitions; d) Replace, as far as possible, the requirements associated with standards published since the edition 2.1, especially IEC 61513, IEC 60880, IEC 62138, IEC 62566 and IEC 62566-2; e) Review the existing requirements and update the terminology and definitions; f) Extend the scope of the standard to all hardware (computerized and non-computerized) and to all safety classes 1, 2 and 3; g) Complete, update the IEC and IAEA references and vocabulary; h) Check possible impact of other IAEA requirements and recommendations considering extension of the scope of SC 45A; i) Highlight the use of IEC 62566 and IEC 62566-2 for HPD development; j) Introduce specific activities for pre-existing items (selection, acceptability and/or mitigation); k) Introduce clearer requirements for electronic module-level design, manufacturing and control; l) Complete reliability assessment methods; m) Introduce requirements when using automated tests or control activities; n) Complete description of manufacturing control activities (control process, assessment of manufactured equipment, preservation of products); o) Define and ensure the inclusion of a graded approach for dealing with the 3 different classes of equipment and related requirements. IEC 60987:2021 fournit des exigences et des recommandations pour les aspects materiels des systemes dI&C, quelle que soit la technologie, et sapplique a toutes les classes de surete de maniere graduelle (comme cela est defini par l’IEC 61513). Les exigences definies dans le present document guident en particulier la selection des composants preexistants, les aspects materiels de la conception detaillee et de la mise en ouvre du systeme et la fabrication des equipements. Cette troisieme edition annule et remplace la deuxieme edition parue en 2007. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) Modification du titre; b) Prise en compte du fait que les exigences en matiere de materiel sappliquent a toutes les technologies dI&C, y compris des equipements cables conventionnels, des equipements numeriques programmables ou une combinaison de ces deux types dequipements; c) Alignement de la norme sur les nouvelles revisions des documents de l’AIEA SSR-2/1, incluant autant que possible une adaptation des definitions; d) Remplacement, autant que possible, des exigences associees aux normes publiees depuis la parution de l’edition 2.1, plus particulierement l’IEC 61513, l’IEC 60880, l’IEC 62138, l’IEC 62566 et l’IEC 62566-2; e) Revision des exigences existantes et mise a jour des definitions et de la terminologie; f) Elargissement du domaine dapplication de la norme a tout le materiel (informatise et non informatise) et a toutes les classes de surete 1, 2 et 3; g) Complement et mise a jour des references et du vocabulaire de l’IEC et de lAIEA; h) Verification de limpact eventuel dautres exigences et recommandations de lAIEA envisageant lextension du domaine dapplication du SC 45A; i) Mise en evidence de lutilisation de l’IEC 62566 et de l’IEC 62566-2 pour le developpement du HPD; j) Introduction d’activites specifiques pour les constituants predeveloppes (selection, acceptabilite et/ou compensation); k) Introduction d’exigences plus claires pour la conception, la fabrication et le controle au niveau des modules electroniques; l) Methodes completes devaluation de la fiabilite; m) Introduction d’exigences lors de lutilisation d’essais automatises ou dactivites de controle; n) Complement concernant les activites de controle de la fabrication (processus de controle, evaluation des equipements fabriques, preservation des produits); o) Definition et incorporation dune approche graduelle pour traiter les 3 differentes classes dequipements et les exigences qui sy rapportent.
