Hazardous area certification in Australia: what operators check

The most common mistake an international technology vendor makes with Australia is assuming an ATEX marking will get equipment onto a classified-area site. It will not, on its own. Australia runs on the IECEx scheme and the AS/NZS 60079 series of standards, and ATEX is a European directive rather than a certification scheme. For an operator, the practical effect is simple: the equipment that goes into a Zone 1 area on an Australian site needs IECEx certification, or an accepted equivalent assessment, not just a CE mark and an ATEX number. This is the gap that strands good equipment in the approval process.

What Australia actually recognises

Australia uses the AS/NZS 60079 series, which is harmonised with the international IEC 60079 series. The national certification scheme, ANZEx, is harmonised with the international IECEx scheme. Equipment certified to IECEx can be used in Australia almost without exception, without separate national testing. That is the clean path.

Why an ATEX mark is not the same thing

ATEX is an EU directive. It sets essential health and safety requirements, and for some equipment categories the manufacturer can self-assess and self-declare conformity. IECEx, by contrast, is a third-party certification scheme based on testing by an accredited laboratory and a certificate issued by an accredited body. Australia does not automatically accept an ATEX self-declaration, so equipment marked only to ATEX usually needs a conformity assessment to show it meets a level of safety equivalent to IECEx.

What operators check at the gate

An operator's electrical and HSE team will look for a current IECEx or ANZEx Certificate of Conformity, and they will check that the gas group and temperature class on the certificate suit the area. For an installation, they will expect a Hazardous Area Verification Dossier under AS/NZS 60079.14, and they will expect the people installing and inspecting the equipment to hold the relevant competency. These are not optional extras. They are what makes the equipment legal to energise on site.

The trap with equipment assemblies

A single certified device is straightforward. An assembly of several certified items is not. An IECEx certificate for an assembly is not automatically accepted in Australia unless it is validated against the current AS/NZS 60079.14, or the assembly is independently inspected. Vendors who ship a packaged system assuming the assembly certificate covers everything often find the real compliance work starts on arrival.

What good looks like, with two examples

Two of the technologies in the Hub gallery show the right approach. Air2Work's E-Compressor, a mobile breathing air system for confined space and tank work, carries ATEX Zone 1 and IECEx certification. Xshielder's enclosure turns an iPhone into an IECEx Zone 1 device for use in classified areas. In both cases the IECEx certification is the part that makes them usable on an Australian site, provided the gas group and temperature class match the area.

Where this leaves a vendor entering the market

For a vendor, the lesson is to treat IECEx certification and the AS/NZS 60079 installation requirements as part of market entry, not an afterthought once equipment is in country. The certification pathway, the gas group and temperature class, the assembly question, and the dossier all need to be settled before equipment ships. Getting that right is the difference between equipment that energises on schedule and equipment that sits in a warehouse while a conformity assessment is arranged.

Common Questions

Is ATEX certification accepted in Australia?

Not automatically. Australia runs on IECEx and the AS/NZS 60079 series. ATEX is an EU directive that allows manufacturer self-declaration for some categories, so equipment marked only to ATEX usually needs a conformity assessment to show an equivalent level of safety.

What certification does hazardous area equipment need in Australia?

It needs a current IECEx or ANZEx Certificate of Conformity under the AS/NZS 60079 series, with a gas group and temperature class that suit the classified area.

What is the difference between ATEX and IECEx?

ATEX is a European directive that can be self-certified by the manufacturer for some categories. IECEx is a third-party certification scheme based on accredited testing and a certificate from an accredited body, which is why Australia accepts it.

Does IECEx-certified equipment need extra testing in Australia?

Generally no. IECEx-certified equipment is accepted in Australia almost without exception, without separate national testing, because AS/NZS 60079 is harmonised with IEC 60079.

Are equipment assemblies treated differently from single devices?

Yes. An IECEx certificate for an assembly of several items is not automatically accepted unless it is validated against the current AS/NZS 60079.14 or the assembly is independently inspected.

What is a Hazardous Area Verification Dossier?

It is the set of documents showing that an installation complies with its equipment certificates and with AS/NZS 60079.14. Electrical inspectors ask to see it for hazardous area installations.

What do operators check before energising equipment in a Zone 1 area?

They check a current IECEx or ANZEx Certificate of Conformity, the correct gas group and temperature class, the verification dossier, and that the people installing and inspecting the equipment are competent to do so.
