ISO 20471 High Visibility
High Visibility Garments
High visibility (hi vis) workwear is essential for industries that operate around traffic, motorised vehicles or work in low visibility. The main purpose of high visibility is to ensure that employees stand out in poorly lit conditions and that they are clearly visible from all angles. All of the garments within this category have ISO 20471 certification which is the international standard for testing high visibility workwear. There are three main components of hi-vis clothing, fluorescent material, reflective strips and contrast material.
| Class 1 | Class 2 | Class 3 | |
| Reflective Tape | 0.10 sqm | 0.13 sqm | 0.20 sqm |
| Fluorescent Material | 0.14 sqm | 0.50 sqm | 0.80 sqm |
