PORTABLE APPLIANCE TESTING
What is test and tag?
Test and Tag is a process of carefully visually inspecting each appliance for damage to flex, connections, guards, covers and plug by a competent technician. Once the technician is assured the item is safe to electrically inspect, the item’s insulation, earthing and polarity may be tested to ensure it is electrically safe.
What standard do we comply with?
The current Australian standard, AS/NZS 3760:2022 specifies the test and tag required to be conducted by Professional Air Solutions technicians in order to confirm the electrical safety of portable electrical appliances. A Portable Appliance Tester (PAT) should be used to conduct these tests, the use of a PAT remains one of the most comprehensive and efficient methods of ensuring an items electrical safety. Our technicians use a sophisticated PAT and thermal printer to test and tag your electrical appliances and print tags on site.
Visual Test
A visual inspection is conducted by our technicians and involves a comprehensive inspection of flexible supply cord, plug, appliance and socket. Covers and guards are checked to ensure they are attached, appliances are checked for rattles indicating the presence of small foreign objects that may interfere with the safety of the appliance, and Class II appliances are checked for deep engraving, which may impact on the insulation of the appliance.
Electrical Test
The following electrical tests are required to be completed on the appropriate equipment under AS/NZS 3760:2022.
- Insulation Resistance
- Leakage Current Testing
- Polarity
- Earth Resistance
