Microwave Ovens

To satisfy AS/NZS 3760:2010 microwave ovens are required to be visually inspected and have the standard earthing and insulation tests conducted.

However, there is another hazard associated with microwave ovens that needs to be checked before Jez Test and Tag could, in good conscience, declare the equipment safe – RADIATION LEAKAGE!

It’s generally accepted that the most common cause of radiation leakage in microwave ovens is faulty, damaged or worn door seals.  Key factors that can cause damaged or wear to the door seals are dirt or food particles caught in the door seals and hinges, slamming the door too often and too hard, excessive or careless cleaning, and general wear and tear.

Microwave radiation can be very harmful to humans and, even though there is no legal requirement, it would be reckless of us to confirm that a microwave oven is “safe” without first conducting the electrical safety tests required by AS/NZS 3760:2010, as well as the radiation leakage tests required by AS/NZS 60335.2.25:2011.

The tests that we carry out to satisfy the requirements of AS/NZS 3760:2010 are an initial visual inspection, the Earth Continuity test, and the Insulation resistance and/or Current Leakage tests as appropriate.

This will be followed by the radiation leakage test required by AS/NZS 60335.2.25:2011, which will check that the power density of microwave radiation emerging from the microwave oven does not exceed 5 milliwatts per square centimetre at any point 5 centimetres or more from the external surface of the unit (5mW/cm2).

Once the microwave oven has been tested and passed, tags will be affixed indicating that the unit has been tested to the requirements of both AS/NZS 3760:2010 and AS/NZS 60335.2.25:2011.
