Recently the Australian and New Zealand Standard AS/NZS 3760 went through a makeover and has now officially changed. We’ve done the hard work and summarized everything you need to know about the changes relating to the test and tag industry and how it affects your work. We've also summarised everything below for a quick summary.
Some simple but notable changes include the Standard now including the words ‘RCD’ in the title of the Standard, along with the year changing it to AS/NZS 3760:2022 (formerly 2010).
This isn't of course going to affect how you test and tag or anything close to it, but it's important to be aware of this change when referring to the most recent Standard.
For people in New Zealand, it is now a requirement to keep records of testing and inspection with a register of all equipment that is inspected/tested. This essentially means everyone testing and tagging must keep a register of all equipment that is tested. For anyone offering test and tag as a service provider (as a 3rd party) they will be required to document exact test measurements for every test performed, rather than a simple pass or fail. It then specifically mentions examples of Earth continuity resistance, Insulation Resistance and Leakage Current. This is especially important when buying a new PAT Tester, as you'll want to make sure it complies with the new reporting requirements, which some of the basic level appliance testers can't perform.
For anyone in Australia, the above point is highly recommended, but not compulsory based on how it’s worded differently. For people in Australia it states that records “should be kept”, as opposed to New Zealand which says “records shall be kept”.
Another noteworthy alteration is that there is an extra mention of VSD’s (variable speed drives), which indicates that extra support will be required when dealing with VSD’s.
This is mentioned in the Leakage Current table 2.1 on page 15. It specifically states "For equipment containing a variable speed power drive system, alternative requirements to leakage current requirements that may be accepted are included IEC 61800-5-1 Edition 2.1 Advanced technical support may be required for assessement.
When discussing a Competent Person (which is someone who is able to test and tag in Australia or New Zealand), AS/NZS 3760 2022 now specifically mentions that skills and knowledge should be maintained and updated, essentially going into more detail when compared to the previous version. It also uses the words 'should be maintained' as opposed to 'may need to be updated'.
This is a significant point as this is an area we've been pointing out for many years now and really trying to make sure our students are constantly staying up-to-date with the most recent skills and know-how. Because if you've completed a course years ago, it's most likely that you're not fully up-to-date with everything.
In this same section, it now mentions that a Compentent Person should have an understanding of the risks associated with electrical equipment, something which is brought up during our test and tag course.
It’s worth pointing out that majority of the changes in the Australian and New Zealand Standard aren’t critical elements when testing. Instead, the changes mostly involve actual wording changes within the booklet, such as it being easier to read, extra dot points and breaks, more images of PAT Testers and a better flow of content. As a result, there are now an addition 13 pages in the Standard compared to the previous version.
Likewise, table numbers have been changed, which at first glance isn’t a big deal. It’s more noticeable for highly used and referred to tables such as the test and tag intervals which was previously Table 4 and has now become Table 2.4. The bottom section that previously mentioned both repaired and second hand testing in the same line have been split and their associated standards listed.
For anyone that would like clarification on any of the changes or extra support, please don’t hesitate to contact us anytime with any questions.
