Household microwave ovens - Methods for measuring performance

IEC 60705:2024 applies to microwave ovens for household and similar use, it also applies to microwave ovens with grills and combination microwave ovens. This document defines the main performance characteristics of these appliances, which are of interest to the user, and it specifies methods for measuring these characteristics. The manufacturer defines the primary cooking function of the appliance, microwave function or thermal heat. The primary cooking function will be measured with an existing method according to energy consumption. If the primary cooking function is declared as a microwave function, IEC 60705 will be applied for energy consumption measurement. If the primary cooking function is declared as a thermal heat, IEC 60350-1 will be applied for energy consumption measurement. If the manufacturer does not declare the primary function, the performance of the microwave function and thermal heat is measured as far as it is possible. There is currently no measurement method for the energy consumption for grilling and steam functions. This document does not deal with safety requirements (see IEC 60335-2-25 [1] ). This document does not apply to appliances incorporating thermal heat, steam function or hot steam function only. These appliances are covered by IEC 60350-1. This fifth edition cancels and replaces the fourth edition published in 2010, Amendment 1: 2014 and Amendment 2: 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) thematically ordered new sequence of the clauses; b) updated normative references; c) introduced a new definition for microwave generator to open the standard for microwave ovens with one or more magnetrons or solid-state components; d) aligned with IEC 60350-1:2023 regarding the definitions and references; e) aligned preparation of water load for Clause 8 and Clause 10; f) removed the definitions for set to off mode and set to standby mode ; g) added new definitions regarding low power modes; h) aligned the low power mode measurement, Clause 11, to IEC 60350-1:2023; i) revised square tank tests to one new 12.2; j) revised the dishes used for Clause 12, Clause 13 and Clause 14 and removal of Annex B; k) removed A.3.3; l) removed Annex F for measuring the energy consumption of the cooling down period; m) former Annex E will be substituted by a supporting document located on the IEC's website.

Mikrowellengeräte für den Hausgebrauch - Verfahren zur Messung der Gebrauchstauglichkeit

Fours à micro-ondes à usage domestique - Méthodes de mesure de l'aptitude à la fonction

L'IEC 60705:2024 s'applique aux fours à micro-ondes à usage domestique et analogue. Il s'applique également aux fours à micro-ondes avec grils et aux fours à micro-ondes combinés. Le présent document définit les principales caractéristiques d'aptitude à la fonction de ces appareils qui intéressent les utilisateurs, et spécifie les méthodes de mesure pour évaluer ces caractéristiques. Le fabricant définit la fonction de cuisson principale de l'appareil, la fonction micro-ondes ou la chaleur thermique. La fonction de cuisson principale est mesurée au moyen d'une méthode existante en fonction de la consommation d'énergie. Si la fonction de cuisson principale est déclarée comme une fonction micro-ondes, l'IEC 60705 est appliquée pour le mesurage de la consommation d'énergie. Si la fonction de cuisson principale est déclarée comme une chaleur thermique, l'IEC 60350-1 est appliquée pour le mesurage de la consommation d'énergie. Si la fonction principale n'est pas déclarée par le fabricant, l'aptitude à la fonction micro-ondes et à la fonction chaleur thermique est mesurée autant que possible. Aucune méthode de mesure de la consommation d'énergie n'est actuellement disponible pour les fonctions gril et vapeur. Le présent document ne traite pas des exigences de sécurité (voir l'IEC 60335-2-25 [1] ). Le présent document ne s'applique pas aux appareils qui comportent seulement une fonction chaleur thermique, une fonction vapeur ou une fonction de vapeur chaude Ces appareils sont couverts par l'IEC 60350-1. Cette cinquième édition annule et remplace la quatrième édition parue en 2010, l'Amendement 1:2014 et l'Amendement 2:2018. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) nouvel ordre thématique des articles; b) mise à jour des références normatives; c) ajout d'une nouvelle définition de générateur de micro-ondes pour étendre la norme aux fours à micro-ondes avec un ou plusieurs magnétrons ou composants à semiconducteurs; d) alignement des définitions et des références sur l'IEC 60350-1:2023; e) alignement de la préparation de la charge d'eau pour l'Article 8 et l'Article 10; f) suppression des définitions de mise en mode arrêt et mise en mode veille; g) ajout de nouvelles définitions relatives aux modes faible puissance; h) alignement du mesurage de la consommation des modes faible puissance (Article 11) sur l'IEC 60350-1:2023; i) révision des essais avec récipient carré dans un nouveau 12.2; j) révision des plats utilisés pour l'Article 12, l'Article 13 et l'Article 14, et suppression de l'Annexe B; k) suppression du A.3.3; l) suppression de l'Annexe F pour le mesurage de la consommation d'énergie de la période de refroidissement; m) l'ancienne Annexe E sera remplacée par un document d'accompagnement disponible sur le site web de l'IEC.
