CSA Z96 and AS/NZS 1906.4: Hi-Vis Compliance for Canada, Australia and NZ
The short answer
CSA Z96 is the Canadian hi-vis standard, with three classes based on the amount and configuration of fluorescent and retro-reflective material, plus levels of retro-reflective performance (Level 1 and Level 2). AS/NZS 1906.4 is the Australian and New Zealand standard for high-visibility materials, used together with AS/NZS 4602.1 to classify day, night and day-and-night garments (D, N and D/N). Neither accepts EN ISO 20471 or ANSI/ISEA 107 marking.
If you supply Canada, Australia or New Zealand, the class system looks familiar but the marking does not transfer, and customs or site inspectors check the marking.

Key takeaways
- CSA Z96 has three classes and two retro-reflective levels (Level 1 and Level 2).
- AS/NZS uses D, N and D/N to show whether a garment is for day, night or both.
- Local practice can be stricter than the standard, especially on mining and rail sites.
- Dual or multi-certified garments are normal for international suppliers.
- Tape certification is part of the chain in every one of these systems.
1. Standard vs use case vs purchasing notes
| Standard | Region | Typical use case | What to check when buying |
|---|---|---|---|
| CSA Z96 Class 1 | Canada | Low-risk sites, visitors | Minimum area and configuration, Level 1 or 2 tape |
| CSA Z96 Class 2 | Canada | Roadway, construction, logistics | Configuration and sleeve coverage for the higher classes |
| CSA Z96 Class 3 | Canada | High-speed traffic, night work | Full coverage, front-back-side visibility |
| AS/NZS 4602.1 with 1906.4 — D | Australia, New Zealand | Daytime work in daylight | Fluorescent fabric performance to 1906.4 |
| AS/NZS 4602.1 with 1906.4 — N | Australia, New Zealand | Night work | Retro-reflective performance and layout |
| AS/NZS 4602.1 with 1906.4 — D/N | Australia, New Zealand | Day and night use | Both fluorescent and reflective requirements |
2. How the three systems compare
| Concept | CSA Z96 (Canada) | AS/NZS (AU/NZ) | EN ISO 20471 (EU/UK) |
|---|---|---|---|
| Basis of classification | Class 1–3, plus Level 1–2 tape | D, N and D/N garment use | Class 1–3 by material area |
| Daytime requirement | Fluorescent background | Fluorescent material to 1906.4 | Fluorescent area threshold |
| Night-time requirement | Retro-reflective configuration | Retro-reflective material and layout | Retro-reflective area threshold |
| Marking | Standard, class and level on the garment | Standard and D/N marking | Standard and class |
| Interchangeability | None | None | None |
3. What to specify on a purchase order
| Item | Specification to write | Why |
|---|---|---|
| Standard and class | "CSA Z96 Class 2 Level 2" or "AS/NZS 4602.1 D/N" | The class system differs from the EU and US |
| Tape | Certified tape to the local standard | Tape certified for EN ISO 20471 may not satisfy the local test |
| Colour | Fluorescent yellow-green or orange per local practice | Local mining and rail rules often specify |
| Configuration | Number and layout of bands, front, back and sides | Configuration is part of the class definition |
| Local add-ons | Reflective piping, ID panels, rail-issued specifications | Site rules can exceed the standard |
4. Frequently asked questions
What is CSA Z96?
It is Canada's high-visibility clothing standard. It defines classes based on the amount and configuration of fluorescent and retro-reflective material and two levels of retro-reflective performance.
What does AS/NZS 1906.4 cover?
It covers the performance of high-visibility materials, including fluorescent and retro-reflective fabrics and tapes. Garments are then classified for day, night or day-and-night use under AS/NZS 4602.1.
Can I use an EN ISO 20471 garment in Canada or Australia?
Not for a contract or site requiring the local standard. The marking must match the jurisdiction, so specify certification to CSA Z96 or AS/NZS where you sell into those markets.
What does D/N mean on a hi-vis garment?
It shows the garment is suitable for both day and night use, meeting the fluorescent requirements for daytime and the retro-reflective requirements for night.
Do mining and rail sites accept the standard alone?
Often not. Many sites publish their own specifications on top of the standard, including colours, reflective piping and identification panels.
Are these garments more expensive than EU-standard ones?
Usually slightly, because the tape and test programmes differ and volumes are smaller. Multi-certified garments cost more again, since they carry several test programmes.
