Microwave heating categories
Your oven 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 microwave ovens 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.
