Test and Tag

AIMAC Electronics can Test and Tag your equipment to comply with AS/NZ3760 (General electrics) and AS/NZ3551 (Medical devices). Either as a one off or a regular maintenance compliance contract.

Test and tagging is a generic name given to the process of visually inspecting and electrically testing in-service electrical equipment for personal safety. Colloquially, it is also referred to as; tagging, test tag, test and tag, electrical tagging, appliance testing, portable appliance test or lead tagging.

The aim of test and tagging is to determine if the appliance is electrically safe for personal use. The appliance undergoes a visual inspection for defects such as damage or missing components and a number of electrical tests to measure earth continuity, insulation resistance and polarity.

In Australia and New Zealand, this is done using the Standard; AS/NZS 3760:2010 “In-service inspection and testing of electrical equipment” as a reference document.

Electrical safety and regular yearly inspections of your electrical tools, appliances, power leads, extension leads and all other workplace and home electrical equipment are not to be taken lightly.

Each year in New Zealand there are dozens of workplace related deaths caused by electrocution and many more serious injuries or destructive fires. The more shocking stats are for the home. Most of these could have been prevented with regular Test and Tag inspections.

This is why it is now WH&S legislation that some businesses, contractors, sole traders operating in a working environment must have a regular test and tag performed on their electrical equipment if they want to be compliant with the AS/NZS 3760:2010.

AIMAC Electronics can give you piece of mind that your home and or workplace and the people in it are safe from defective electrical equipment. We also test microwaves for faults as well as radiation leaks which can be harmful to your health and in some cases deadly.

Frequently Asked Questions

Why must I inspect, test and maintain my electrical equipment?

If you are an employer, you have a duty of care to ensure that employees and visitors to the workplace are safe from injury and risks to health. You must therefore manage any safety risks surrounding electrical hazards, in accordance with the requirements of the WH&S Act AS/NZS 3760:2010. You must apply a systematic risk management approach to eliminate or control the risk of electrical hazards. After the risk assessment, you can then implement a range of control measures including:

  • routine visual checks
  • regular inspection
  • maintenance
  • repair
  • replacement
  • use of residual current devices (RCDs)
  • and, where warranted, testing of identified electrical equipment.

Are there any special requirements for construction work?

Yes. Due to the hazardous nature of construction work regular inspection and testing of electrical equipment is warranted and must be carried out. The requirements are outlined in the WorkSafe NZ Code of Practice – Electrical practices for construction work

Are there any special requirements for hired electrical equipment?

Yes. Electrical equipment that has been serviced or repaired which could have effected electrical safety must be inspected, tested and tagged in accordance with the requirements of the Standard, AS/NZS 3760:2010 prior to the equipment being placed back into service

What is a hostile working environment?

This is a working environment where the electrical equipment is normally subjected to events or operating conditions likely to result in damage to the equipment or a reduction in its expected life span. This includes, but is not limited to:

  • physical or mechanical damage
  • exposure to:
    •  moisture
    •  heat
    •  vibration
    •  corrosive chemicals
    •  dust
    •  fumes

Safety and inspection of electrical equipment revised Standard published AS NZS 3760

In-service safety inspection and testing of electrical equipment AS/NZS 3760:2010 provides a process to reduce the risk of electrical shock to users of electrical equipment. The Standard covers electrical equipment that connects to the mains supply by a flexible cord and plug. AS/NZS 3760 is used by electricians and electrical contractors that inspect electrical equipment.

AS/NZS 3760 has been completely revised and the key changes to the Standard are as follows.

  • 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.
  • Table 4 has been reviewed to align with the Electricity (Safety) Regulations 2010. Changes have been made to some requirements, including allowing for the intervals between testing to be varied, based on a risk analysis.
  • Equipment with functional earthing has been identified – such equipment does not need an earth continuity test.
  • The Standard now includes information for leakage current tests on Class II single-phase and three-phase equipment, and leakage current test methodology for equipment that is normally immersed in water.
  • New information to test three phase residual current devices (RCDs) and electrical equipment has been added to improve user safety.
  • AS/NZS 3760:2010 In-service safety inspection and testing of electrical equipment.
  • AS/NZS 3551:2004 Technical management programs for medical devices.
