AS/NZS 4602.1 & 1906.4: The Australian Hi-Vis Standards Most Buyers Get Wrong

A buyer once sent us a photo of a container of hi-vis vests, rejected at an Australian port. The vests were EN ISO 20471 certified, CE marked, beautiful quality. They were also illegal to sell in Australia, because the importer had assumed "European certified" meant "Australian compliant."

It does not. Australia runs its own two-standard system, and the gap between it and the European system trips up even experienced importers. Here is the map we use when quoting Australian programs.

The Two-Standard System: Design + Materials

Australian hi-vis compliance is built on two standards that work together:

AS/NZS 4602.1 — the garment design standard. It tells you how to build the garment: how much fluorescent fabric, where the tape goes, what the classes mean.

AS/NZS 1906.4 — the materials standard. It tells you what the materials must do: how bright the fluorescent fabric must be, how the tape must perform under headlights, how both must survive washing and UV exposure.

A compliant garment must satisfy both. You can have the perfect design (4602.1) made from non-compliant fabric (fails 1906.4) — that garment fails. You can have certified materials assembled into a non-compliant design — that also fails. Both standards, both passed, or the garment is not compliant.

This is different from Europe, where EN ISO 20471 covers both design and materials in one standard. The Australian split means your supplier needs to test the materials separately from the garment design — and you need to see both certificates.

AS/NZS 4602.1: The Design Standard

The 2024 edition (AS 4602.1:2024, replacing AS/NZS 4602.1:2011+A2:2020) defines three classes:

Class D — Day Only Fluorescent fabric, no retroreflective tape. For workers visible in daylight but not near traffic at night. This is the uniquely Australian category that does not exist as PPE in Europe — a Class D polo shirt or vest would not qualify as hi-vis PPE under EN ISO 20471 at all.

Australia runs enormous Class D volumes: mining site polos, construction work shirts, outdoor vests. The logic is heat — Australia is hot, tape adds weight and reduces breathability, and most outdoor work happens in daylight. If your program is day-only, Class D is cheaper and cooler than taped garments. But it is useless after dark.

Class N — Night Only Retroreflective tape, fluorescent background not required (though often present). For workers visible only at night under vehicle headlights. Rare in practice — most programs need day visibility too.

Class D/N — Day and Night Fluorescent fabric PLUS retroreflective tape. The default for construction, road work, and any program where workers might be out after dark. This is the Australian equivalent of EN ISO 20471 Class 2 or 3 — but the areas and tape geometry differ, so an EN Class 2 garment does not automatically meet AS/NZS Class D/N.

The 2024 update added garment levels (Level 1, 2, 3) aligned with risk assessment, ensemble classifications for multi-garment systems, and — critically — women's-specific fit guidance. If your workforce includes women, the 2024 edition is the first Australian standard that explicitly addresses fit for diverse body types.

AS/NZS 1906.4: The Materials Standard

The 2023 edition (AS/NZS 1906.4:2023, replacing AS/NZS 1906.4:2010+A1:2014) defines the performance requirements for the materials inside the garment:

Fluorescent background fabric classes:

• Class F — fluorescent material (the standard choice, usually polyester)
• Class NF — non-fluorescent high-visibility material (usually cotton, for hot climates — lower colour intensity but better breathability)
• Class RF — combined retroreflective and fluorescent (for materials that do both jobs)

  Retroreflective tape class:

• Class R — retroreflective material (the tape itself)

  What changed in 2023 that you need to know:

  1. Two new colours: Pink and green joined yellow, orange-red and red as compliant fluorescent colours. This matters for programs that need colour-coding by role or gender — pink is now a legitimate compliant option, not a fashion colour.

  2. Two new material classes: Class NF(W) for non-fluorescent materials that pass wet-weather requirements, and Class SP for retroreflective materials where one part meets Class R and another meets Class F.

  3. Optional extended wash testing: Manufacturers can now claim durability beyond the standard 5 wash cycles if they pass additional testing. If your program involves industrial laundering, ask for the extended wash test results.

  If your supplier is still quoting to AS/NZS 1906.4:2010, they are using a superseded standard. The 2023 edition is current.

  The Practical Difference: What This Means for Your Program

  If you are sourcing for Australia, your RFQ must specify:

  1. Both standards, both editions: "AS 4602.1:2024 garment design, AS/NZS 1906.4:2023 materials"

2. The class: D, N, or D/N (and if D/N, the garment level from the 2024 edition) 3. The colour: yellow, orange-red, red, pink or green — by standard name, not by eye 4. The fabric class: F (fluorescent) or NF (non-fluorescent, for hot climates) 5. Testing evidence: material test reports for 1906.4, garment design compliance for 4602.1

If your program is multi-market (you sell the same garment in Australia and Europe), the garment needs dual certification: EN ISO 20471 for Europe, AS/NZS 4602.1 + 1906.4 for Australia. Some labs can run both test sequences on the same samples — cheaper than two separate programs, but budget for both.

If you are buying from a supplier who says "our EN certification covers Australia" — it does not. Ask for the AS/NZS test reports. If they cannot produce them, the garments are not Australian-compliant, full stop.

The Mistake That Costs Buyers Real Money

The most common failure we see: an importer sources EN ISO 20471 Class 2 vests from a European supplier, ships them to Australia, and discovers at customs (or worse, at a site safety audit) that the vests do not meet AS/NZS Class D/N because the tape geometry is wrong or the fluorescent area is measured differently.

The fix is not complicated, but it must happen before production: specify the Australian standards in the RFQ, ensure the factory tests to Australian methods, and verify both certificates (materials + design) before the goods ship.

We run Australian programs routinely — mining polos in Class D, construction vests in Class D/N, rail programs with the additional AS 7471 requirements. The testing is done to order with SGS or Intertek, and both certificates (1906.4 materials, 4602.1 design) ship with the goods.
