High-visibility clothing



EN ISO 20471

This norm specifies the requirements for high-visibility clothing that visually signals the presence of a worker. High-visibility clothing has to work in every light condition   to make one visible by vehicle or machine operators   at daylight or under artificial illumination.

High-visibility garments have a fluorescent surface combined with retroreflective material. There are 3 different certified grades:

Classe 3 pittogramma

Class 3 – Highest grade
The highest visibility grade, required for those who work on highways, main roads or airports. It must include at least 0,80 m2 of reflective surface
and 0,20 m2 of retroreflective material (4 meters by 5 cm of reflective band).

Classe 2 pittogramma

Class 2: Intermediate level
Required for anyone who works on A and B roads, also for vehicle drivers. It must include at least 0,50 m2 of reflective surface and 0,13 m2 of retroreflective material (2,60 meters by 5 cm of reflective band).

Classe 1 pittogramma

Class 1: Minimum level
Minimum level required for those who work on private roads, or as an addition to higher class clothing. It must include at least 0,14 m2 of reflective surface and 0,10 m2 of retroreflective material (2 meters by 5 cm of reflective band).


EN ISO 20471 Class 3 combined
There are two ways of reaching Class 3 protection under EN ISO 20471: either choosing a certified Class 3 product, or two products that together can be certified Class 3.

ISO 13688 – Protective clothing – general requirements
The international standard specifies the general requirements and recommendations for the ergonomics, ageing, dimensioning and marking of protective clothing with the information provided by the manufacturer. Each certified garment in this catalogue is also certified ISO 13688. This standard substitutes EN340.

High-visibility equipment for medium-risk conditions
Norm EN 17353 applies to clothing and equipment used in medium-risk situations, in areas where low-speed vehicles are used, and in areas where EN ISO 20471 for high-visibility is not required. It is intended for clothing used under daylight conditions (during the day), in the dark (at night), or both at daylight and in the dark.


Type A: Equipment for daylight conditions
Equipment to use where the worker risks not being seen only under daylight conditions. This type uses only fluorescent materials for higher visibility.


Type B: Equipment for dark conditions
Equipment used where the worker risks not being seen only in dark conditions. This type only uses fluorescent material for higher visibility.


Type AB: Equipment for daylight, twilight and dark conditions
Equipment used where the worker risks not being seen at daylight, at twilight and in dark conditions. This type uses fluorescent and retro-reflective materials, and/or combinations of both for higher visibility.

EN 13356 – Visibility accessories for non-professional use
This standard specifies the performance requirements for accessories meant for non-professional use. Visibility accessories under this standard are meant to give visibility to users on dimly lit or dark roads.

EN 14058 – Clothing for protection in cool environments
This standard specifies the requirements and testing methods to guarantee the heat retention performance of clothing in cool environments. Cool environments are defined as a possible combination of humidity and wind at temperatures of -5 °C and above. At moderately low temperatures, these garments can be used not only outdoors, but also for indoors activities. In these cases, garments do not need to be made with waterproof materials. Therefore, these requirements are optional under this standard.
