Before appliances can be deemed safe, a competent technician must complete both a visual and an electrical test as part of a comprehensive test and tag process.
A visual test involves a comprehensive inspection of parts such as the plug, supply cord and socket for any signs of visible damage. Guards and covers are checked to ensure they are correctly attached. The appliance is further tested for rattles that could indicate the presence of small loose objects that may interfere with the appliance’s safety. Class II appliances must be checked for deep engravings that could impact the insulation of the device. More than 90% of defects are detectable by visual inspection.
AS/NZS 3760:2022 requires the following electrical tests to be conducted on appropriate appliances:
All portable appliances with a removable plug, flexible cable, and a voltage of more than 50V must be tested and certified safe. These requirements apply to equipment used for business purposes such as printers and computers, as well as other appliances on the premises like refrigerators, kettles, and toasters. Microwave ovens must be tested for radiation leakage.
As a precaution, it is best to test and tag all appliances on the premises to avoid missing any. After a competent person concludes the test, he will provide you with documentation detailing the status of all appliances tested, along with failed item reports to be kept as a record of the safety status of your business appliances.
