AS/NZS 1906.4:2010

Visibility saves lives. Whether working near moving vehicles, on offshore rigs, or in high-risk construction zones, workers must be seen to stay safe. AS/NZS 1906.4:2010 sets the requirements for high-visibility and retro-reflective materials used in safety garments.

This standard ensures that garments signal a wearer’s presence under varying light and weather conditions — from bright daylight to low-light or nighttime environments.

Scope of AS/NZS 1906.4:2010

The standard applies to:

  • Fluorescent materials for high daytime visibility
  • Retro-reflective materials for night and low-light conditions
  • Combined materials that meet both requirements

It specifies photometric and colorimetric properties, ensuring consistent brightness, reflectivity, and color performance across different conditions.

Classes of high-visibility materials

AS/NZS 1906.4 defines multiple classes of materials based on their performance:

Class Description Application
Class F Fluorescent material for high daytime visibility Outdoor work in daylight conditions
Class F (W) Fluorescent material tested for wet weather Daytime outdoor work in rain/wet conditions
Class R Retro-reflective material for low-light or nighttime visibility Roadworks, night operations, offshore decks
Class RF Combined retro-reflective and fluorescent material Protection across both day and night
Class NF High-visibility non-fluorescent material Specialized use where non-fluorescent materials are required

Class RF garments offer the broadest coverage, ensuring visibility both day and night.

When AS/NZS 1906.4 Matters

High-visibility clothing is a critical element of personal protective equipment across industries:

  • Maritime & Offshore – reflective gear ensures workers are visible on decks and in emergency evacuations.
  • Petrochemical – high-visibility garments reduce accident risks around moving equipment and vehicles.
  • Construction – essential for roadside works, cranes, scaffolding, and heavy machinery zones.

By defining strict visibility classes, AS/NZS 1906.4 ensures garments meet consistent performance levels across environments and weather conditions.

Frequently asked questions

What is the difference between Class F and Class R?
Class F provides visibility in daylight (fluorescent colors). Class R ensures visibility in low-light or night (retro-reflective materials).
What is Class RF?
It combines Class F and R requirements, making it suitable for both day and night.
What does Class F (W) mean?
It indicates fluorescent material tested for wet weather, ensuring performance during rain.
Why is high-visibility clothing important in construction and offshore industries?
Because workers often operate near vehicles, cranes, or machinery where being seen can prevent accidents.
Does the standard cover garment design?
No. AS/NZS 1906.4 specifies material properties. Garment design is covered under separate standards (e.g., AS/NZS 4602).
