Testing Frequency

The current Australian Standard, AS/NZS 3760:2010 specifies the tests required to be conducted in order to confirm the electrical safety of an item.
Whilst the New Zealand Standard does not mandate 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.

Visual Testing

A visual inspection is conducted by EPASS 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 Testing

The following electrical tests are also required under AS/NZS 3760:2010.
  • Insulation Resistance
  • Leakage Current Testing
  • Polarity
  • Earth Resistance
