B-field Exposure From Induction Cooking Appliances 33
5 Assessments According to EN50366 conditions
One objective of this study was to measure whether the B-field exposure from the three selected
induction cookers complies with the derived and basic restrictions of the ICNIRP guidelines,
when assessed according to the European Norm EN50366.
5.0.1 Measuring Conditions in EN50366
The European Norm EN50366 describes a method for the evaluation and measurement of the
electromagnetic field in the vicinity of appliances such as induction hobs and hotplates.
Figure 23: Measuring distances, according to EN50366. Lines (A, B, C, D) indicate the measur-
ing positions for an induction cooker with 4 hobs in operation. The probe is here positioned on
line A. [4]
Measuring distance and operator distance, according to EN50366 The measuring
distance is the distance between the surface of the appliance and the closest point on the sensor
surface. The operator distance is the distance between the surface of the appliance and the closest
point of the head, limbs or torso of the operator. For each cooking zone, the measurements are
made along four vertical lines (A, B, C, D) at a measuring distance of 30 cm from the edges of
the appliance (see Figure 23). The measurements are made up to 1 m above the cooking zone
and 0,5 m below it. The measurement is not made at the rear of the appliance if the appliance
is intended to be used when placed against a wall.
Operating mode, according to EN50366 An enameled steel cooking vessel, filled to 50 %
of its capacity with tap water, is placed centrally on the cooking zone to be measured. The
smallest vessel recommended in the instructions for use is used. If no recommendations are
provided, the smallest standard vessel that covers the marked cooking zone is used. The bottom
