EN 471 - High-visibility warning clothing for professional use - Test methods and requirements

This standard details test methods and performance requirements for clothing designed to enhance the wearer’s visibility in poor and low lighting, during bad weather, and in locations with mechanical hazards. Requirements include very bright colours (e.g., fluorescents) and retroreflective features (i.e., those with high reflectivity).

Design specifications include the minimum required retroreflective surface areas and the configuration of those areas.

• X = classification of the fluorescent and retroreflective material
Classes 1 to 3 (in which 3 is the highest)

• Y = classification of the retroreflective material’s quality
Level 1 and 2 (in which 2 is the best)
