microwave heating categories
Your microwave has been tested and labelled to meet the government’s voluntary agreement on the
reheating of pre-cooked food.
The heating characteristics and output power levels of microwaves are usually calculated using a
relatively large portion of food (a 1000 gram load, IEC 705) but many packs of pre-cooked food are
sold in smaller packs, often about 350 grams.
The government, in partnership with food companies and microwave manufacturers, have set up a
system of heating categories to help you choose the reheating time for pre-cooked food.
800W is the output power of the microwave.
E is the heating category for your microwave.
Check the cooking times for category E
on the food’s packaging to see how long it
should be cooked for. Please see the below
example for reference.
