Microwave Leakage Testing Frequency

However protection against microwave leakage in microwave ovens is specifically tuned to the frequency of the microwaves 2 4 ghz and is not expected to prevent other frequencies to get through.

Microwave leakage testing frequency.

I found the cause was often the door interlock the oven would work but the door was not fully closed there was a very slight gap and would leak around the door area. Microwave leakage testing falls under th. A source of electromagnetic radiation microwaves are produced inside the oven by an electron tube called a magnetron. Emitting high frequency radio waves this then heats and cooks the food.

Information on microwave leakage testing is not within the remit of this code of practice because it does not directly relate to electrical safety. Wi fi signals use a similar frequency to microwave ovens so this is an interesting test. A microwave emission label is then normally attached to the appliance showing that the microwave radiation levels outside the appliance are acceptable for safe use. There s no reason not to as with all equipment used in the workplace the employer has a duty to inspect and maintain to ensure the safety of all.

I used to test microwave ovens for leakage before and after the repair. Microwave leakage testing falls under the australian standard as nzs 60335 2 25 household and similar electrical appliances safety. This requirement was removed from the code of practice when it was updated from the 3 rd to the 4 th edition. Testing of the microwave oven involves measurement of the radiation levels around the oven using a microwave leakage detector to ensure compliance with the 5 mw cm2 limit.

Knowing how to use a microwave leakage detector can be a handy add on for anyone who offers test and tag as service. Microwaves typically operate at around 2 45 gigahertz whilst cellular signals tend to be around 1 9. If this happens it could mean that your appliance is leaky or it could just mean that your particular model is designed only to contain radiation at certain frequencies. I did find some commercial ones had a problem not a lot but yes some did leak.

Knowing how to use a microwave leakage detector can be a handy add on for anyone who offers test and tag as service. Previously microwave leakage testing was part of the standard pat test. Cell phone frequencies are very different in the 800 to 1900 mhz range so there s no reason to expect your microwave to block them.
