Household electric cooking appliances - Part 2: Hobs - Methods for measuring performance

IEC 60350-2:2011 defines methods for measuring the performance of electric hobs for household use. Appliances covered by this standard may be built-in or for placing on a working surface or the floor. The hob can also be a part of a cooking range. This standard defines the main performance characteristics of these appliances which are of interest to the user and specifies methods for measuring these characteristics. This standard does not specify requirements for performance. This first edition of IEC 60350-2 is related to IEC 60350:1999 which shall be separated in two parts: one part for cooking ranges, ovens and steam ovens and the other part for hobs. This part 2 of IEC 60350 covers hobs, and IEC 60350-1 covers ovens.

Appareils de cuisson électrodomestiques - Partie 2: Tables de cuisson - Méthodes de mesure de l'aptitude à la fonction

la CEI 60350-2:2011 définit des méthodes de mesure de l'aptitude à la fonction des tables de cuisson électriques à usage domestique. Les appareils couverts par la présente norme peuvent être encastrés, ou prévus pour être placés sur un plan de travail ou posés sur le sol. La table de cuisson peut également faire partie d'une cuisinière. La présente norme a pour objet de définir les principales caractéristiques d'aptitude à la fonction de ces appareils, qui intéressent l'utilisateur, et de spécifier des méthodes pour la mesure de ces caractéristiques. La présente norme ne spécifie pas les exigences d'aptitude à la fonction. La première édition de la CEI 60350-2 est liée à la CEI 60350:1999, qui doit être séparée en deux parties: une partie consacrée aux cuisinières, aux fours et aux fours à vapeur, et l'autre partie aux tables de cuisson. La présente partie 2 de la CEI 60350 traite des tables de cuisson, et la CEI 60350-1 traite des fours.

Foreword
This document (EN 60350-2:2013) consists of the text of IEC 60350-2:2011 prepared by IEC/SC 59K
"Ovens and microwave ovens, cooking ranges and similar appliances", of IEC/TC 59 "Performance of
household and similar electrical appliances", together with the common modifications prepared by
CLC/TC 59X "Performance of household and similar electrical appliances".
The following dates are fixed:
(dop) 2014-06-03
• latest date by which this document has to be implemented
at national level by publication of an identical
national standard or by endorsement
• latest date by which the national standards conflicting (dow) 2016-06-03
with this document have to be withdrawn
Together with EN 60350-1:2013, this document will supersede EN 50304:2009/EN 60350:2009 +
A1:2010/A11:2010.
EN 50304:2009/EN 60350:2009:
1) a method to measure energy consumption of hobs
a) that is representative for a real cooking process, for which after the heat up phase a
simmering phase has been implemented in the measurement. Water as a standardised load
is used. Food is theoretically considered in the experimental setup but not used as that leads
to insufficient reproducibility. The ranking between the technologies will not be changed by
different methods/applications, so the energy consumption is measured only by one energy
optimised method.
b) that is applicable to compare different electrically heated technologies like e.g. induction,
radiant or solid plates
c) that leads not to a comparison with gas burners. Gas hobs are covered by EN 30-2-1.
d) that fulfil requirements of repeatability and reproducibility (crucial for energy measuring
purposes). Therefore the cooking process is defined on the temperature level 90 °C to avoid
influence on the boiling point by ambient pressure.
e) that is applicable for hobs with different layouts and cooking zone / area sizes.
This method is based on the method described in TC59X/217/DC.
2) definition of cooking areas:
Following new market trends a definition for cooking areas is given. A definition is necessary as
cooking areas have other demands e.g. for positioning the cookware or selecting the cookware sizes
than cooking zones.
3) definition of standardised cookware also for big cooking zone sizes:
For a high reproducibility a standardised cookware shall be used. Therefore a self made cookware is
defined up to a size of 330 mm bottom diameter.Evaporating water by holes in the lid simulates a
cooking process on a higher temperature level. The thermal energy which is needed to keep at
boiling point for a real cooking process including evaporation and the energy uptake of the food
during the simmering phase is considered by the holes.
4) additional requirements (according to EN 50564) how to measure low power modes.

- 3 - EN 60350-2:2013
5) under consideration:
A control procedures for checking measured values in comparison to values declared by the
manufacturer under consideration of permitted tolerances. WG10 with the support and sponsorship of
CECED believes that it is fundamental to proceed with a Round Robin Test procedure of this draft
amendment to confirm requirements of repeatability and reproducibility and to estimate the standard
deviation of the method itself.
Clauses, subclauses, notes, tables, figures and annexes which are additional to those in
IEC 60350-2:2011 are prefixed “Z”.
Words in bold in the text are defined in Clause 3.
According to the decision D137/061 for CLC/TC 59X, this European Standard has been drawn up as a
document which follows, as far as suitable, the structure of IEC 60350-2:2011.
It also describes the evaluation of data declared by the manufacturer and control procedures for checking
these values.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association.
This European Standard is suitable for direct comparison and is considered sufficiently reproducible
within given limits for the purpose of setting the ecodesign requirements for hobs according to the
Directive ERP 2009/125/EC.
Endorsement notice
The text of the International Standard IEC 60350-2:2011 was approved by CENELEC as a European
Standard with agreed common modifications.
