EN 81346-1:2009

Industrial systems, installations and equipment and industrial products - Structuring principles and reference designations - Part 1: Basic rules

IEC 81346-1:2009, published jointly by IEC and ISO, establishes general principles for the structuring of systems including structuring of the information about systems. Based on these principles, rules and guidance are given for the formulation of unambiguous reference designations for objects in any system. The reference designation identifies objects for the purpose of creation and retrieval of information about an object, and where realized about its corresponding component. This edition includes the following substantial changes with respect to the previous one: - a new introductory clause providing a description and explanation to the concepts used elsewhere in the publication; - a more comprehensive description of the structuring principles and rules for structuring are provided; - 'other aspects' are introduced, and the prefix sign # is assigned to these aspects; - the concept of reference designation group has been deleted; - the specific term 'transition' has been avoided and been replaced by an improved textual description of this phenomenon in annex D; - a new clause about labelling is introduced; - the old annexes have been removed with the exception of the annex showing an example of the application of reference designations within a system; - a new annex explaining the manipulation of objects is introduced; - 4 new annexes are introduced as rearrangement of detailed examples or explanatory information.

Systèmes industriels, installations et appareils, et produits industriels - Principes de structuration et désignations de référence - Partie 1: Règles de base

La CEI 81346-1:2009 publié conjointement par la CEI et l'ISO établit les principes généraux pour la structuration des systèmes y compris la structuration des informations sur ces systèmes. Sur la base de ces principes, des règles et des lignes directrices sont données pour la formulation de désignations de référence non ambiguës applicables aux objets d'un système quel qu'il soit. La désignation de référence identifie des objets afin de la création et de la récupération d'informations sur un objet, et où réalisé au sujet de son composant correspondant. Cette édition inclut par rapport à la précédente les modifications techniques majeures suivantes: - un nouvel article d'introduction donnant une description et une explication des concepts utilisés dans le cadre de la présente publication; - une description plus complète des principes et des règles de structuration; - l'introduction d''autres aspects' auxquels on assigne le signe # comme préfixe; - la suppression du concept de groupe de désignations de référence; - le terme spécifique 'transition' a été évité et remplacé par une description textuelle améliorée de ce phénomène en annexe D; - l'introduction d'un nouvel article concernant l'étiquetage, - le retrait des anciennes annexes à l'exception de celle qui représente un exemple de l'application des désignations de référence au sein d'un système; - l'introduction d'une nouvelle annexe expliquant la manipulation des objets; - l'introduction de 4 nouvelles annexes correspondant à une réorganisation des exemples détaillés ou des explications.
