ISO 20471: high visibility clothing

ISO publishes ISO 20471 covering high visibility clothing capable of signalling the wearer visually, with test methods and requirements. Listings in this corpus name it on high visibility protective coveralls rather than on Australian hi-vis workwear.

What is ISO 20471?

ISO 20471 is the international standard for high visibility clothing, published by ISO and often written EN ISO 20471. It is the international counterpart to the Australian designation AS/NZS 4602.1, and on this hub it appears on high visibility protective coverall listings.

ISO 20471 is the international standard for high visibility clothing. It is the European and international counterpart to the Australian designation AS/NZS 4602.1, and it appears here on hi-vis disposable coveralls.

Frequently asked questions

Is ISO 20471 the same as AS/NZS 4602.1?

No. Both cover high visibility clothing, but they are separate documents with their own requirements and their own class systems. Australian hi-vis workwear listings name AS/NZS 4602.1. If your workplace specifies the Australian designation, buy a garment that names it.

Why does a disposable coverall name ISO 20471?

Because the coverall is manufactured to international specifications and the hi-vis version is certified against the international high visibility standard. Guides on this hub name whichever designation the product listing names, without translating one into the other.

Does a class number under ISO 20471 match a Class D or D/N marking?

No, and they should not be treated as equivalent. The Australian marking describes daytime, night time or combined use, and the international standard uses its own class system. Read the marking that is actually on the garment.
