but i believe it was recently removed as such, and been replaced with something a long the lines of a visual inspection for damage, checking operation of door mechanism and using the device in the manner for which it is intended.
Or this was certainly the situation in all canteen/tea bar areas within the armed forces, as it turns out we should have been a bit more worried about the high power air defence radars. Which come highly recommended if you want to ensure female offspring.
2. MICROWAVE OVENS
The incidence rate to date for injuries (such as thermal tissue
damage) arising at microwave ovens from exposure to microwave
radiation appears minimal. Lack of cleanliness and poor maintenance
of door seals can lead to leakage in excess of the recommended limit
of 5 mW/cm². Maintenance or service contracts with manufacturers
or suppliers are to be recommended.
Taken from HSE, although service/maintenance contracts are not something which is mandatory.
