Annotation of standard text IEC 60704-3-ed.3.0 :
IEC 60704-3:2019 describes procedures for determining and verifying the declared values of the noise emitted by household and similar appliances. It applies to all categories of household and similar electrical appliances covered by IEC 60704-1 and all parts of IEC 60704-2, which include particular requirements for special categories of appliances. It applies to appliances being produced in quantity, such as in batches, series or lots, which are manufactured to the same technical specification and characterized by the same declared value of noise emission. This part of IEC 60704: – considers the term "declaration" to include all means for providing information on the noise emission values to potential users (consumers) of the appliances; this includes labels, brochures, advertisements, commercial and technical information papers, etc.; – considers the declaration for appliances manufactured by mass production; – specifies a simple statistical method for verifying the declared values by investigating a sample of only three appliances. This International Standard is to be used in conjunction with IEC 60704-1:2010 and the latest edition of IEC 60704-2 (all parts). This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: a) in Annex A, standard deviations that are now specified for various appliance categories in the parts of IEC 60704-2 have been excluded from Table A.1; b) furthermore, this edition makes reference to new standards and is implementing ISO/IEC Directives, Part 2 in a more accurate manner. LIEC 60704-3:2019 decrit les methodes de determination et de verification des valeurs declarees du bruit emis par les appareils domestiques et analogues. Elle sapplique a toutes les categories dappareils a usage domestique et analogue couverts par lIEC 60704-1 et toutes les parties de lIEC 60704-2, qui contiennent des exigences particulieres applicables a certaines categories dappareils. Elle sapplique aux appareils produits en quantite (en serie, en lots) fabriques suivant les memes specifications techniques et caracterises par la meme valeur declaree demission sonore. La presente partie de lIEC 60704: – utilise le terme "declaration" pour englober tous les moyens utilises pour fournir des informations sur les valeurs demission sonore aux utilisateurs potentiels (consommateurs) des appareils; ce terme inclut les etiquettes, les notices, les publicites, les fiches techniques et commerciales dinformation, etc.; – traite de la declaration pour des appareils fabriques en serie; – decrit une methode statistique simple pour verifier les valeurs declarees en etudiant un echantillon limite a trois appareils. Cette Norme internationale doit etre utilisee conjointement avec lIEC 60704-1:2010 et la derniere edition de lIEC 60704-2 (toutes les parties). Cette troisieme edition annule et remplace la deuxieme edition parue en 2006. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) dans lAnnexe A, les ecarts-types qui sont a present specifies pour differentes categories dappareils dans les parties de lIEC 60704-2 ont ete exclus du Tableau A.1; b) en outre, cette edition fait reference a de nouvelles normes et met en application les Directives ISO/IEC, Partie 2 dune maniere plus precise.
