B-field Exposure From Induction Cooking Appliances 59
6.1.4 Appliance 3
Single-hob measurement using pot 3, large pot, standard set of pots Figures 46 and
47 depict the B-field measured in the vicinity of appliance 3 with pot 3 (large pot, standard set
of pots) centered and non-centered. Figure 46 depicts the front side measurements, and Figure
47 the measurements at the rear, left and right sides of the appliance. The B-field does not
exceed the ICNIRP limit (6.25 µT) for a measuring distance of 30 cm, according to EN50366.
However, at the front side of the appliance, Figures 46 f) and h) (pot non-centered) show
that the ICNIRP limit is exceeded for a measuring distance of 12 cm. The maximum rms-values
of the measured B-field are 3.7 µT and 18 µT (measuring distance of 1 cm) for a centered and
non-centered pot, respectively. Moreover, Figure 47 shows that the ICNIRP limit is exceeded
for a measuring distance of 5 cm, 4 cm and 3 cm for the rear, left and right sides of the appliance,
respectively, when the pot is centered, and 14 cm, 14 cm and 13 cm for the rear, left and right
sides of the appliance, respectively, when the pot is non-centered. The corresponding maximum
rms-values of the B-field measured (measuring distance of 1 cm) are 12.5 µT, 11 µT, 9 µT (rear,
left and right sides, pot centered) and 22.5 µT, 22.5 µT and 22 µT (rear, left and right sides, pot
non-centered).
Single-hob measurement using pot 13, standard set of pots, small size Figures 48
and 49 show the B-field measured in the vicinity of appliance 3 with pot 13 (small pot, standard
set of pots) centered and non-centered. Figure 48 depicts the front side measurements, and
Figure 49 the measurements at the rear, left and right sides of the appliance. The B-field does
not exceed the ICNIRP limit (6.25 µT) for a measuring distance of 30 cm, according to EN50366.
However, at the front side of the appliance, Figures 48 a) and e) (pot centered), as well as a
f) and h) (pot non-centered) show that the ICNIRP limit is exceeded for a measuring distance
of 4 cm and 19 cm for a centered and non-centered pot, respectively. The maximum rms-values
of the B-field measured are 9 µT and 34 µT (measuring distance of 1 cm) for a centered and
non-centered pot. Moreover, Figure 49 shows that the ICNIRP limit is exceeded for measuring
distances of 10 cm, 9 cm and 10 cm for the rear, left and right sides of the appliance, respectively
when the pot is centered, and 24 cm, 24 cm and 25 cm for the rear, left and right sides of the
appliance, respectively, when the pot is non-centered. The corresponding maximum rms-values
of the B-field measured (measuring distance of 1 cm) are 24 µT, 24 µT, 25 µT (rear, left and right
sides, pot centered) and 51 µT, 55 µT and 57 µT (rear, left and right sides, pot non-centered).
Single-hob measurement using pot 8, worst-case set of pots Figures 50 and 51 depict
the B-field measured in the vicinity of appliance 3 with pot 8 (worst-case set of pots) centered and
non-centered. Figure 50 depicts the front side measurements, and Figure 51 the measurements
at the rear, left and right sides of the appliance. The B-field does not exceed the ICNIRP limit
(6.25 µT) for a measuring distance of 30 cm, according to EN50366.
However, at the front side of the appliance, Figures 50 a), b) and e) (pot centered), as well as
f) and h) (pot non-centered) show that the ICNIRP limit is exceeded for a measuring distance
of 6 cm and 20 cm for a centered and non-centered pot, respectively. The maximum rms-values
of the B-field measured are 11.5 µT and 35 µT (measuring distance of 1 cm) for a centered and
non-centered pot. Moreover, Figure 51 shows that the ICNIRP limit is exceeded for measuring
distances of 13 cm, 13 cm and 14 cm for the rear, left and right sides of the appliance, respectively,
when the pot is centered, and 22 cm, 24 cm and 24 cm for the rear, left and right sides of the
appliance, respectively, when the pot is non-centered. The corresponding maximum rms-values
of the measured B-field (measuring distance of 1 cm) are 30 µT, 30 µT, 34 µT (rear, left and right
