You can test the power setting of a cooking zone by
measuring how long it takes to bring a specific amount of
water to the boil.
The pan (and lid) must be stainless steel or enamel. The
diameter of the pan must match the cooking zone, and be
flat-bottomed or slightly concave.
^
Take a note of the diameter and wattage of the cooking
zone to be tested (see "Cooking zones").
^
Fill the pan with the quantity of water given in the table. The
temperature of the water should be approx. 20 °C.
^
Place the pan with its lid on the cooking zone.
^
Switch on the cooking zone at the highest setting.
^
Note the time it takes for the water to boil.
The power setting for the cooking zone is fine if the water
boils within the time given in the table.
The time can vary if:
- there are fluctuations in the mains electricity supply,
- very cold water is used,
- an unsuitable pan is used,
- the pan is not covered.
