If a hob is a combination from ZA.2.2 and ZA.2.3, then these areas will be tested separately.
Add an additional sentence at the end:
If a hob has more than one cooking area with limitative marking (see ZA.2.3), each cooking
area is tested separately.
Add a further line in Table ZA.1 and change the line “5 controls” as stated:

ZA.3.3 Positioning on a cooking area with limitative markings
ZA.3.3.1 with ≤ 3 controls
The largest piece of cookware is positioned in the centre of the cooking area. To find the
centre the longest vertical and horizontal line within the marking is determined. Bisect the
horizontal line and move the vertical line parallel to this half distance point.
vertical
NOTE The wording “horizontal” and “vertical“refer to the drawing layer.
horizontal
Intersect the horizontal line (longest possible) at 25 %, 50 % and 75 %. 25 % determines the
position marker , 50 % determines the position marker and 75 % determines position
marker .
The position marker determines the center for the largest piece of cookware.
The smaller pieces of cookware are positioned centrally on the position marker and,
(see Figure ZA.3).

Figure ZA.3 - Example - position a cookware set for measuring the energy consumption
for cooking areas with limitative markings ≤ 3 controls
The next biggest cookware piece has to be placed in accordance with the following order of
precedence:
a) segmented area being located at the rear of the hob;
b) segmented area being located at the left.
If a cookware is not detected at the described position, for this position the next biggest
cookware diameter is chosen independent from the cookware category (see Table Z.3).
The positions and sizes of the pieces of cookware used for measuring shall be noted.
ZA.3.3.2 with > 3 controls
The position of the pieces of cookware for a cooking area with more than 3 controls is
defined by following procedure.
First the longest possible horizontal and vertical lines within the marked area which shows the
limits where the cookware is used are determined. Bisect the vertical line and move the
horizontal line parallel to this half distance point.
Intersect the horizontal line (longest possible) at 20%, 50% and 80%. 20 % determines the
position marker , 50 % determines the position marker and 80 % determines position
marker .
The position marker determines the center for the largest piece of cookware.
The smaller pieces of cookware are positioned tangentially (=outer radius of cookware bottom
touches the position markers) one above and one below the horizontal line at the position
markers and , (see Figure ZA.4).
The two pieces of cookware with the diameter of 210 mm are positioned one below the
position marker and one above the position marker . The cookware with the diameter
of 180 mm is set above the position marker and the cookware with 150 mm diameter is
below the position marker .
If a cookware is not detected at the described position, for this position the next biggest
cookware diameter is chosen independent from the cookware category (see Table Z.3).
If the position of the specified cookware causes the cookware to partially cover the control,
then the cookware must be moved away, until the cookware no longer covers the control.
Moreover all pieces of cookware shall be as far as possible within the marked area. If
necessary, the biggest cookware on position marker is shifted first vertically then
horizontally. The other pieces of cookware are shifted first horizontally then vertically.
The pieces of cookware should be shifted as little as possible. If the shifting in the first
direction is not effective it can be skipped.
The positions and sizes of the pieces of cookware used for measuring shall be noted.
If it is not clear which cookware position is correct, all possibilities are assessed.
