The requirements for vision strips on glazing have been updated, with the key requirements now covered by AS 1428.1–2021, which replaced the 2009 edition. The updated standard clarifies placement, dimensions, and contrast rules to improve safety and accessibility.

KEY REQUIREMENTS IN AS 1428.1–2021 ARE:

• Placement heights: Vision strips must be installed at two distinct horizontal bands:
  • Between 900 mm and 1000 mm above the floor.
  • Between 1400 mm and 1600 mm above the floor.
• Width: Each strip must be at least 75 mm wide.
• Contrast: Strips must achieve a minimum 30% luminance contrast against the background surface, ensuring visibility from both sides of the glazing.
• Continuity: Strips must run continuously across the full width of the glazed panel or door.
• Visibility: They must be clearly visible under all lighting conditions, including natural and artificial light.
• Application: Applies to any glazing that could be mistaken for a doorway or opening, including glass walls, partitions, and doors.

HOW HAVE THE STANDARDS CHANGED?

Clause 6.6 on vision strips has effectively been updated.

The original requirements were set out in AS 1428.1–2009, but as of 29 July 2025, the AS 1428.1–2021 edition is now the referenced standard for compliance under both the National Construction Code (NCC/BCA) and the Disability (Access to Premises – Buildings) Standards 2010.

📌 What Changed

• Old reference: Clause 6.6 of AS 1428.1–2009 specified how visual indicator strips (warning strips) must be applied to glazing — including their height, width, contrast, and placement.
• New reference: The AS 1428.1–2021 edition is now the governing standard. This means that for new building work, compliance must follow the updated 2021 provisions, not the 2009 ones.
• Practical impact: Installers, designers, and certifiers must now use the 2021 requirements when applying vision strips to glazing in accessible buildings.

🧩 Why Vision Strips Matter

• They are safety features applied to glass doors, partitions, and panels to prevent people (especially those with vision impairments) from accidentally walking into clear glazing.
• Strips must be contrasting in colour, placed at specific heights, and visible from both sides of the glass to meet accessibility standards.

⚠️ Key Notes for Compliance

• Existing buildings: If glazing was installed under the 2009 standard, it remains compliant for those works.
• New projects: Any building work approved after July 2025 must comply with AS 1428.1–2021.
• Common issues: Many defects arise from strips being installed at the wrong height or with insufficient contrast, so careful adherence to the updated diagrams and specifications is critical.

✅ Summary

• AS 1428.1–2009 Clause 6.6 is no longer the active reference.
• AS 1428.1–2021 now sets the rules for vision strips on glazing.
• Compliance requirements have shifted, so designers and builders should review the updated 2021 standard.
