Reference standard, not for use alone, but only in association with another standard containing the protection performance requirements. This standard specifies general performance requirements for ergonomics, innocuousness, size designation, durability, ageing, compatibility and marking of protective clothing and the information to be supplied by the manufacturer with the protective clothing.

This standard specifies the requirements for protective clothing aiming to signal the presence of the wearer visually, so that he may be detected and seen in hazardous situations, in all conditions of daylight, and night under illumination of car headlights. There are three classes of high-visibility clothing. Each class must have minimum surfaces of visible material constituting the garment; the higher the class, the more visible the garment: – CLASS 1: Background material (Fluorescent): 0.14 m² Retroreflective material (Bands): 0.10 m² – CLASS 2: Background material (Fluorescent): 0.50 m² Retroreflective material (Bands): 0.20 m² – CLASS 3: Background material (Fluorescent): 0.80 m² Retroreflective material (Bands): 0.20 m² Background material: Yellow, orange/red or red fluorescent material intended to be highly conspicuous. Retroreflective material: Classified into 2 levels. The highest level of retroreflection gives the best contrast and visibility of high-visibility clothing seen in darkness, under headlamps. Marking: X : Class of high visibility surface (from 1 to 3) X : Performance level of the retro-reflective material (1 to 2)
