The Standard

Australian Standard AS/NZS 3760:2010 specifies the necessary safety inspection and maintenance standards for Australia. It describes the safety inspection and testing of single and 3-phase (polyphase) (240v - 415v) portable electrical equipment, and machinery connected to supply by a flexible lead or cord which is currently in use, being returned to service, being presented for re-sale or hire. Depending on the use of the equipment, inspection and testing intervals vary, from daily up to years between tests.

Required Testing

As specified by the standard, the following tests will be applied, dependant upon the type of equipment.

  • A visual inspection
  • Earth conductor continuity
  • An Insulation test
  • Active & neutral polarity connection
  • portable RCD function

Failure of any of these tests will deem the item unsatisfactory for use and it shall be removed from service for repair or disposal. Your test and tag representative will consult with you to determine if minor repairs (plug tops etc) are practicable.

Testing Frequency

The minimum retest frequency is set out in AS/NZS 3760:2010. You may wish to retest more frequently to minimise risk to your workers or the general public, but you may not decrease the frequency without a written and maintained Risk Assessment Document.
(We can assist you with this if you wish to go down that path).

As a guide:-

Hire equipment- 3 months
Factories and workshops - 6 months
Offices etc - 12 months
Residential parts of hotels or institutions - 2 years
Environments where cord is not flexed - 5 years

Frequency

There is some interpretation allowed in these categories. Eg You may consider a hairdressing salon is like an office but in fact it is more like a factory as cords on hairdryers, for instance, are flexed frequently and their risk of failure is much higher than in an office.

New Equipment

Where new equipment is introduced into service, between scheduled testing, the equipment supplier warrants its safety and it need not be tested. However, it must be visually inspected for any transport damage and tagged as "New Equipment" .
