Annotation of standard text IEC 81346-2-ed.2.0 :
IEC 81346-2:2019 establishes classification schemes with defined object classes and their associated letter codes, and is primarily intended for use in reference designations and for designation of generic types. The classification schemes are applicable for objects in all technical disciplines and all branches of industry. IEC 81346-2:2019 has the status of a horizontal standard in accordance with IEC Guide 108. It is also intended for use by technical committees in preparation of publications related to reference designations in accordance with the principles laid down in IEC Guide 108. IEC 81346-2:2019 cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The entry classes of the classification scheme have been defined to reflect the “inherent function†of the object classified; b) The classes are defined to align with the principles of ISO 22274 and ISO 704; c) A three-level classification scheme has been defined, which provides a greater flexibility for the designer in some technical fields; d) Classes are defined by their definition and provided with a preferred term. Examples are provided if needed; e) A separate classification scheme for spaces has been provided. IEC 81346-2:2019 etablit des plans de classification et definit les classes d’objets ainsi que leurs lettres codes associees, et est principalement destinee a un usage dans les designations de reference et pour la designation des types generiques. Les plans de classification s’appliquent aux objets appartenant a toutes les disciplines techniques ainsi qu’a toutes les branches dindustrie. IEC 81346-2:2019 a le statut de norme horizontale conformement au Guide IEC 108. Elle est egalement destinee a etre utilisee par les comites d’etudes pour l’etablissement de publications liees aux designations de reference conformement aux principes exposes dans le Guide IEC 108. IEC 81346-2:2019 annule et remplace la premiere edition parue en 2009. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) Les classes d’entree du plan de classification ont ete definies afin de refleter la «fonction intrinseque» de l’objet classe; b) Les classes sont definies de sorte a s’aligner sur les principes definis dans l’ISO 22274 et l’ISO 704; c) Un plan de classification a trois niveaux a ete defini afin de garantir au concepteur une plus grande latitude dans certains domaines techniques; d) Les classes sont definies avec un terme preferentiel. Des exemples sont fournis, si necessaire; e) Un plan de classification distinct a ete fourni pour les espaces.
