High-visibility clothing isn’t just a requirement—it’s a lifesaving layer of protection for workers in construction, roadwork, mining, utilities, and industrial sites. To ensure garments deliver reliable visibility in both day and night conditions, AS/NZS 1906.4 sets strict performance standards for hi-vis materials.
This guide breaks down what the standard requires and how companies can choose compliant, long-lasting hi-vis garments.
AS/NZS 1906.4 is the Australian/New Zealand standard that specifies the performance of high-visibility materials used in safety garments. It focuses on the ability of fabrics to remain visible under various lighting conditions, including daylight, low light, and when illuminated by vehicle headlights.
The standard applies to:
Fluorescent fabrics
Retroreflective tapes
Combined-performance materials
① Color & Fluorescence Performance
Garments must be dyed in certified high-visibility colors such as Hi-Vis Yellow, Hi-Vis Orange, or Hi-Vis Red.
The fabric must maintain luminance and chromaticity after washing and UV exposure.
② Retroreflective Tape Performance
Reflective tape must meet strict retroreflectivity values to ensure visibility at night.
Tape must maintain reflectivity after:
Abrasion
Flexing
Rain
Washing cycles
③ Durability Testing
Materials are tested for:
UV degradation
Colorfastness
Weathering
Washing durability
Only fabrics that maintain performance after testing can be certified.
Improves Worker Safety
High-visibility PPE significantly reduces risks of struck-by accidents, especially in low-light or high-traffic environments.
Ensures Legal Compliance
Many industries in Australia, New Zealand, and global export markets require garments to meet this standard.
