Microwave oven leakage testing

In addition to PAT Testing microwave ovens need to be tested for leakage as well as heating power. 

Microwave ovens are always of a Class I construction. Carrying out a test on these is quite straightforward as one can quite easily get an Earth connection on the metal work to the rear of the oven. Alternatively the fixing screws can be used. Just make sure that the power switch is in the ON position when carrying out the test for Earth Continuity and Insulation Resistance.

Microwave leakage 

Microwave ovens can be heavily used and sometimes abused in a busy kitchen catering for a number of staff and customers. They can in time become damaged and even corroded, if not looked after properly.

It is not unusual to see microwave ovens with broken door hinges, damaged or missing door seals, broken door catches or even cracks to the door glass.

While these ovens are designed and manufactured to operate normally and seal in the microwaves, it is important that there are no gaps in this metallic seal.
