What is Test and Tag? Complete 101 Guide
Test and Tag is the name given to the process of checking the safety of portable electrical appliances. It involves two parts: first visually inspecting the appliance for any damage, followed by electrically testing it with a Portable Appliance Tester.
Once tested, the item is then placed with a tag to confirm that it has in fact been tested, along with showing who tested it, the test date and when the next test is due.
The primary reason behind doing testing and tagging is to ensure the safety of the people in the workplace coming into contact with the appliance, while also minimising the risk of an electrical hazard. If an accident does occur and no testing and tagging was previously completed on that item, the employer may be considered liable.
The AS/NZS 3760 is the Australian and New Zealand Standard that provides guidelines and regulations for the test and tag industry with regards to electrical safety of appliances. It sets out recommendations to issues such as test and tag intervals, defines who can test and tag and general guidelines. This Standard was updated in 2022 with a list of various changes, along with now being called the AS/NZS 3760:2022.
Who needs to test and tag?
Industries such as construction, demolition and mining are required to have their appliances tested and tagged every 3 months. This is because of the harsh nature of the industry which is likely to damage equipment at a faster rate. For each 3 months of testing, the test and tag colours will change for different periods throughout the year, which effectively make certain months coincide with a specific test tag colour.
With the exception of these industries, testing and tagging is not a legislative requirement for other workplaces. However, the employer does have a duty of care to ensure the safety of its employees, meaning that if someone was hurt from an appliance that wasn’t tested and unsafe, they could be found liable. Because of this, it’s the employer’s responsibility to have all portable electrical appliances tested.
For people in the hire industry, there are some minimum requirements. For instance, before equipment is hired out it needs to be visually inspected by the hirer before every lease. The actual appliance needs to be tested also every 3 months, which is the hirer's responsibility when they have possession of it.
Who can test and tag electrical equipment?
There is a common misconception that you must be an electrician to test and tag. However, according to AS/NZS 3760:2022, someone who is considered a ‘Competent Person’ is also able to test and tag in Australia. This is most commonly achieved by undertaking a test and tag course, where that person acquires the knowledge and skills in learning to use a PAT tester.
Once you're qualified, you won't need to keep refreshing your certificate or do any additional courses. You will however need to stay-up-to-date with the latest changes in the AS 3760 Standard and remain competent with the latest skills and knowledge. This is something that we do automatically at Test & Tag Training for all of our past students.
For people living in QLD who want to offer test and tag as a service, they must fulfill an additional requirement for a Restricted Electrical Contractors Licence.
What type of equipment is tested and tagged?
In short, any device that has a flexible cable, a removable plug and is not low voltage (not exceeding 50V). This includes extension leads, cord sets and portable RCD's.
Generally, electrical appliances can be classed as either:
- Class I – this is an earthed appliance i.e. kettles, irons and toasters.
- Class II – double insulated appliances, which are usually identified with a symbol (a square within a square) or with the words ‘Double Insulated’ i.e. most electric drills and hair dryers.
It's worth mentioning that new equipment doesn't need to be tested - just visually inspected and tagged.
How often should appliances be tested and tagged?
The Australian Standard recommend particular test and tag frequencies based on the type of environment the appliance resides in. This is shown in the AS 3760 Standard via 'Table 2.4' which explains the minimum requirement. Sometimes, this might differ depending on a workplaces individual risk assessment.
For example, construction sites are tested generally every 3 months, whereas a factory or a warehouse will be 6 months.

What is a Portable Appliance Tester
A portable appliance tester, also known as a PAT Tester or PAT, is the main piece of equipment used by someone testing and tagging. It allows you to test an electrical appliance to ensure it's safe, which does so by giving you results on whether it passed or failed your particular tests.
There are many factors to consider before you buy an appliance tester, such as deciding on how much you want to spend (they range from $500 up to $3000) how much functionality you'll need and what kind features you want.
There's also different brands to choose from, such as Metrel, Seaward and Wavecom. Generally, the more you spend will mean the more you'll get. Nowadays, you can easily read portable appliance tester reviews on every tester and figure out which is the best one for your needs.
It's worth noting that the majority of defects or faults are usually found during the visual inspection of the electrical appliance, which is conducted before you even use your appliance tester.
Important Test & Tag Terminology
If you’re new to the test and tag industry, you’ll quickly discover there’s a unique vocabulary to master, with specific terms used. To help you get familiar with the essentials, we’ve highlighted some of the most important terms below. For a deeper dive, download our comprehensive Test & Tag Glossary, which covers all the major electrical terms and industry jargon.
PAT Tester Calibration: Calibration is the process of regularly adjusting and testing equipment to ensure it provides accurate and reliable results. This ensures the accuracy of the testing process.
Leakage Current Test: This test verifies that an electrical appliance doesn't leak electrical current, which could be a potential hazard to users. It's a critical safety check and PAT Testers need to have this test as a minimum requirement.
Test and Tag Labels: Also known as electrical test tags or appliance test tags, these attach to electrical appliances to indicate their testing status. Test Tags provide a clear visual reference, showing whether an appliance has passed its safety checks.
Test & Tag Equipment: Testing equipment refers to the tools and devices used to assess the safety of electrical appliances. This includes PAT testers, adaptors, and other testing devices.
3 Phase Testing: This involves checking the electrical safety of machines or equipment that use three electrical power lines or extra-strong electricity. It ensures that these machines are safe to use and won't pose a risk of electrical shock or other hazards.
RBGY: This represents the colour-coding system used on test labels. It stands for Red, Blue, Green, and Yellow, and each colour corresponds to a different testing date.
