EN 471:2003


EN 471 was an European Standard for high-visibility clothing. It was discontinued in 2013 as its successor ISO EN 20471 became valid.


ISO 20471:2013


ISO 20471:2013 specifies requirements for high visibility clothing which is capable of visually signalling the user's presence. The high visibility clothing is intended to provide conspicuity of the wearer in any light condition when viewed by operators of vehicles or other mechanized equipment during daylight conditions and under illumination of headlights in the dark.

Performance requirements are included for colour and retroreflection as well as for the minimum areas and for the placement of the materials in protective clothing.

It specified three classes of garments:

  • Class 1

Class 1 defines the lowest visibility level e.g. High-visibility trousers with two 5 cm reflective bands around each leg. These become Class 3 when worn with a Class 3 jacket.

  • Class 2

The class 2 defines an intermediary visibility level. Example: vests. Two 5 cm bands of reflective around body or on one 5 cm band around body and braces to both shoulders. (This class is required for motor vehicles in France and other continental EU member states).

  • Class 3

The class 3 defines the highest level of visibility. Example jacket with long sleeves, jacket and trouser suit. Two 5 cm bands of reflective tape around the body, arms and braces over both shoulders. Class 3 should be worn when working within 1.2 meters of a Highway with traffic moving in excess of 50 km/h.
