AS/NZS 3760 is a standard created by Standards Australia that outlines a testing method and frequency for electrical appliances. It was created to minimize electrical hazards in the workplace. Appliances are inspected for damage, and various measurements are made to the appliances' earth continuity, insulation, polarity, and physical condition. After testing has determined a pass, a tag is attached to the appliance lead indicating when it was tested, when the next test is due, and a tracking code. Retesting intervals of equipment can vary from 3 months to 5 years, depending of the environment where the equipment is located.
This standard is used in both Australia and New Zealand. Colloquially, the standard is often referred to as Test and Tag. Testing can be done by anyone deemed competent by training or experience. It does not require a registered electrician.
The current regulation is AS/NZS 3760:2010. There is also an amendment: AS/NZS 3760:2010/Amdt 1:2011.
