The frequency of testing is dependent on the equipment being tested and the environment it is used in. AS/NZS 3760:2010 specifies the generally observed safety inspection and maintenance standards for Australia. This includes the safety inspection and testing of single polyphase (240v–415v) portable electrical equipment, and, machinery connect to supply by flexible cord which is currently in-service, available for re-sale or hire. Inspection and testing intervals can range from daily, monthly, 3 months, 6 months, 12 months, 2 years and up to 5 yearly testing schedules.
