EN ISO 20471 standard: high visibility clothing for professional use

Our clothing meets the new EN ISO 20471 standard: high visibility clothing for professional use. What exactly does that mean? What requirements does this clothing have to meet? The number next to the pictogram on the label indicates which class it comes under. This depends on the minimum surface fluorescent and reflective fabric:

  • Class 3 requires 0.8 m² fluorescent surface and 0.2 m² reflective surface.
  • Class 2 requires 0.5 m² fluorescent surface and 0.13 m² reflective surface.
  • Class 1 requires 0.14 m² fluorescent surface and 0.10 m² reflective surface.

The fluorescent fabric is available in the colours orange, yellow and red. The colour coordinates and the illumination factor must be within certain parameters (the illumination factor is the amount of light that is radiated by a surface, before and after being lit up). There are also requirements regarding colour fastness for both the fluorescent and the contrasting colours.

What requirements are set for this standard?

  1. Conditions for placing the reflective borders:
  • The width of the reflective borders is at least 50 mm (or it doesn’t count in the surface calculations and is seen as decorative).
  • A break (for closure system or seam) in the border of reflective fabric is not more than 50 mm. The total of such breaks will not be more than 100 mm in border around the body and 50 mm around sleeves and trouser legs.
  • The space between the 2 reflective borders must be at least 50 mm (with a maximum 20° angle) and these borders must be at the distance of at least 50 mm from the bottom of the garment (such as the hem of the trouser legs).
  • The reflective borders can be attached in various ways. They only count in the surface calculation if they have been applied according to regulations. This means that the torso, the legs and the arms must be encircled 2x (or 1x horizontally with vertical borders over the shoulder).
  1. Conditions for the fluorescent fabric:
  • The fluorescent fabric must encircle at least the torso, the sleeves and the legs by 5 mm.
  • Breaks in the fluorescent fabric by the reflective borders are permitted (such as in the case of Department of Waterways and Public Works garments: the 25 mm vertical reflection border over the sleeves and trouser legs).
  • The ratio of fabric in front and in back will be equal to 50% +/-10%.
