Austest & Co Offers Appliance Testing Services to Ensure Safety in the Workplace

Supplier News

Austest & Co  now offers appliance testing services to ensure product safety. The highly experienced staff will measure the degree of insulation to ensure that the device is electrically insulated against short circuits, cross polarisation, deterioration of cables, burnouts and shorts circuits to earth.  

Electrical appliances are differentiated by a series of IEC protection classes. In testing it is essential for the tester to know the difference in classes and therefore what requirements must be fulfilled before declaring the item electrically safe for use in the workplace. Austest appliance testing services are undertaken by staff who are highly trained and differentiate the classes by the following details:  

  • Class I: single insulated wiring that 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 insulated wiring, therefore no need for an earth lead. Class II is indicated by a double box sign.  
  • Class III: appliances that are supplied at a low voltage (usually called Separated Extra Low Voltage) which must be less than 50 V. These appliances are equipped with a marked transformer that supplies a low voltage to the unit.  
All portable electrical equipment, RCDs and appliances used in a workplace must be regularly inspected and tested. The frequency of inspection and testing varies for different work situations:  
  • Construction and demolition sites: the inspection and testing intervals must be in accordance with AS/NZS 3012:2003
  • Mining sites and operations: quarterly testing and tagging must be carried out on all portable appliances normally used in heavy operating environments such as workshops, mining areas, processing areas, construction sites and similar place
  • Most other workplaces with some exceptions: require a risk management approach to identify the if any testing is necessary and the type of inspection required
