Australian Standard 3760
Jan 04, 2011 AS/NZS 3760:2010 - Summary of the new Australian Testing and Tagging Standard This article featured in the Summer 2010 Edition of Electrical Connection magazine. Over the past 12 months, a group of passionate representatives from various industry groups and associations (including a number of electrical safety experts) have met to review In-service safety inspection and testing of electrical equipment. Recommendations were put forward, and lively debate ensued as to the impact the proposed changes would make not only to industry, but to the safety of employees in Australia and New Zealand.
AS/NZS 3760:2010 is a standard created by Standards Australia that outlines a testing method and frequency for electrical appliances. It was created to minimize electrical hazards in the workplace. Appliances are inspected for damage, and various measurements are made to the appliances' earth continuity, insulation, polarity, and.
Following the comprehensive review, Derek Johns the Chairman of EL-036 In-service safety inspection and testing of electrical equipment, the group charged with the review of the Standard, stated he was confident that 'The revisions to AS/NZS 3760 will help to assure users that electrical equipment is safe when it has been tested and marked in accordance with this Standard. ' Whilst the Standard has been completely revised, there are a few key areas worth noting as they may affect the way your test and tag program is implemented. Responsible Person The new Standard makes specific references to the responsibilities of 'the responsible person' to ensure the competency of technicians undertaking a test and tag program. The responsible person is the owner of the premises, equipment or under the relevant OH&S Act is deemed to be responsible for the safety of the workplace. One of the most important areas of competency is the understanding of the Standard, and I encourage all 'responsible persons' to ensure their test and tag provider owns a current copy of the Standard and understands the changes. Medical Equipment Requirements for medical electrical equipment have been clarified to reduce confusion between the use of AS/NZS 3760 and AS/NZS 3551:2004 Technical management programs for medical devices.

- AS/NZS 3760:2010 is a standard created by Standards Australia that outlines a testing method and frequency for electrical appliances. It was created to minimize electrical hazards in the workplace.
- This standard has been superseded and is referred to as Australian/New Zealand Standard AS/NZS 3760:2010: In-service safety inspection and testing of electrical equipment.
All items that are defined as a medical system are now to be tested under AS/NZS 3551:2004 regardless of whether the individual appliance is deemed to be bio-medical equipment. For example, a standard printer located on a 'crash cart' in a hospital and connected to bio-medical equipment on the 'crash cart' will no longer be tested under AS/NZS 3760:2010 but under AS/NZS 3551:2004. Retesting Frequencies (Table 4) Table 4 of AS/NZS 3760:2010 has been reviewed and now aligns more closely with the NZ Electricity (Safety) Regulations 2010. There are 3 changes to Table 4 worth highlighting. In order to reduce confusion within manufacturing environments, no longer are there different retesting time frames for Class I and Class II equipment. Therefore all portable electrical equipment located in a manufacturing environment is now subject to retesting every six months. The 'Cord extension sets and EPODs' column has been removed, and now incorporated in to one column along with Class I and Class II items.
Portable RCD's used in commercial cleaning are now required to be tested by the 'push button' daily or prior to use (whichever is the longer) and an operating time test conducted every 12 months. It is important to note that as the QLD Electrical Safety Regulations specify retesting time frames based on 'Classes of Work', QLD based test and tag technicians should continue to refer to the QLD Electrical Safety Regulations for detail on retesting time frames. Items with functional earthing The new Standard makes reference to equipment with functional earthing. Care should be taken when conducting an earth bond test to ensure the functional earth is not being tested. A functional earth is not designed for safety, but the internal operation of the equipment and may give an incorrect test result. In addition, the completion of an earth bond test on a functional earth may place the equipment in danger. Leakage current testing The Standard now includes additional information for leakage current tests on Class II single-phase and three-phase equipment.

It also includes leakage current test methodology for equipment that is normally immersed in water. 3 Phase RCD's New guidance information has been added to the Standard for the testing of three phase residual current devices (RCDs) and electrical equipment.
This has been added to improve technician safety. Information on Tag AS/NZS 3760:2010 now specifies that the retest date must be added to the durable, non-reusable, non-metallic tag placed on the item after testing. This is in addition to the requirement for Technician/Company Name, Test or Inspection Date, and whether the item passed or failed testing. This addition has been made to assist workplaces in easily identifying when their appliances are due for retesting. Leased Equipment Whilst the 2003 standard made many references to the requirements for hired equipment, there was no reference to the requirements for the testing and tagging of leased equipment.
In order to clarify, AS/NZS 3760:2010 now states that the hiree or the leasee is responsible for the inspection testing and tagging of hired and leased equipment whilst the equipment is in their possession. The equipment should be inspected tested and tagged by the hiree or leasee in accordance with the retest frequencies detailed in Table 4 of AS/NZS 3760:2010. For example, traditionally leased appliances such as Vending Machines, Water Coolers, Computers, Photocopiers and the like must now be inspected tested and tagged in accordance with Table 4 of AS/NZS 3760:2010 by the lease while the equipment is in their possession.
Appliances with Removable Cord sets AS/NZS 3760:2010 notes specifically that for equipment supplied by a cord set, the intention of the Standard is for the cord set and the equipment to be tested and tagged separately. For example, a Kettle with a removable IEC lead would consist of 2 tests. One test for the Kettle, with a tag applied to the kettle. And one test for the IEC lead, with the tag applied to the plug end of the IEC lead. The newly revised standard, AS/NZS 3760:2010 was launched in Australia in October 2010 and is available for download or hard copy purchase from SAI Global in Australia or in New Zealand, Standards NZ.
Should you engage a test and tag service provider I highly recommend you confirm the technician owns a copy of the new Standard and completely understands the impact of the revisions.

AS/NZS 3760:2010 is a standard created by that outlines a testing method and frequency for electrical appliances. It was created to minimize electrical hazards in the workplace. Appliances are inspected for damage, and various measurements are made to the appliances', and physical condition. After testing has determined a pass, a tag is attached to the appliance lead indicating when it was tested, when the next test is due, and a tracking code.
Retesting intervals of equipment can vary from 3 months to 5 years, depending of the environment where the equipment is located. This standard is used in both Australia and New Zealand. Colloquially, the standard is often referred to as.

Testing can be done by anyone deemed competent by training or experience. It does not require a registered electrician. Many businesses are required to maintain records of their compliance with AS/NZS 3760:2010 and can use tools such as to record testing dates, equipment tested and retest dates. The current regulation is AS/NZS 3760:2010. There is also an amendment: AS/NZS 3760:2010/Amdt 1:2011. References.
