All testing & tagging is conducted by our trained staff to comply with OS&H Legislation and the following Australian Standards:
 AS/NZS 3760  In-service Safety Inspection and Testing of Electrical Equipment.                                                                
AS/NZS 3012  Electrical Installation - Construction and Demolition Sites.                                                                
What tests are carried out during Appliance Testing
Visual inspection is a process of simply inspecting the appliance, cable and plug for any obvious signs of damage. According to statistical data , this process can find more than 90% of faults.

If a fault is found at this stage the equipment / appliance being tested is deemed to have failed and must be tagged appropriately to ensure that it is not used. Further testing of this equipment / appliance must not continue because an unacceptable risk to the tester is introduced, with the potential for electrocution.
At periodic intervals,  Its essential to test the portable appliances to measure the degree of protection and to ensure that it is adequate. These intervals are dependent upon the equipment type and the environment in which it is used. A visual inspection must carried out before progressing to a PAT test.
The tests that an individual must carry out to declare an item electrically safe is dependent on the type of equipment and class of construction (shown below).

These tests are:
- Earth Continuity
- Insulation Resistance
- Polarity
- Earth Leakage

Class I Earth Single insulated wiring which requires an earth connection. There is no symbol for a Class I product so if a rating plate has no symbol on it then it is usually Class I.

Class II Double Earth Double insulated wiring, therefore no need for a earth lead. Class II is indicated by double box.   

EXT / IEC / Powerboard T his equipment type is related to extension leads, equipment power cables and power boards.
