Household electric cooking appliances - Part 2: Hobs - Methods for measuring performance
This part of IEC 60350 defines methods for measuring the performance of electric hobs for
household use.
Appliances covered by this document can be built-in or designed to be placed on a work
surface. The hob can also be a part of a cooking range.
This document does not apply to portable appliances for cooking, grilling and similar functions
(see IEC 61817).
This document defines the main performance characteristics of hobs which are of interest to
the user and specifies methods for measuring these characteristics.
This document does not specify a classification or ranking for performance.
NOTE 1 Some of the tests which are specified in this document are not considered to be reproducible since the
results can vary between laboratories. They are therefore intended for comparative testing purposes only.
NOTE 2 This document does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9).

Uncertainty of measurements
Following IEC/TR 61923 “Household electrical appliances – Method of measuring performance – Assessment of repeatability and reproducibility”, the following expanded uncertainties for measurements according to this European Standard may be assumed.
In 2011, a round robin test was performed with 12 laboratories participating from all over Europe. One of the objectives was to check the robustness and precision of the measurement of energy consumption. Three technologies were tested: “solid plate”, “radiant heater”, “induction”, along with three technologies for the control system: “switch”, “energy regulator”, and “electronic control”. The size of the hobs is the most common one on the market: 60 cm with 4 cooking zones. To cover a reasonable amount of labor only one cooking zone with a diameter of 180 mm were considered.
Results were analyzed by CLC/TC 59X/WG 10 together with CECED, and expanded uncertainties were calculated as shown in Table ZB.1.

b These values are the average of measurement figures taken from different technology, see above. c Not measured in this ring test.
