Microwave ovens can be the most intensely used and abused piece of electrical equipment in a modern kitchen and unless they are maintained and kept clean they can become corroded and dangerous.
Swift PAT have seen these, on many occasions ovens in use with holes in the doors, broken door catches, missing seals, broken hinges, faulty turntable motors and even one oven with the door glass and metal gauze missing.
What We Do;
To test a microwave oven, firstly we visually inspect the appliance and then perform the usual electrical tests as described on the PAT Testing page.
Once we know the oven is electrically sound, We then check that the door interlocks work correctly along with the oven controls and switches.Then a measurement of the radiation level around the door and control panel is taken using our annually calibrated microwave leakage detector ( Emissions ) to ensure the 5 mW/cm2 limit is not exceeded as specified by BS5175.
Finally we test the performance of the microwave by placing two beakers of water in the oven and heating on full power for a pre-determined time. The increase in water temperature is used to calculate the output power.The relevant test labels are placed on the oven and the results noted on our test sheet before a certificate is issued.
