EN ISO 20471 HI VISIBILITY PROTECTION
EUROPEAN HIGH VISIBILITY STANDARD
High-visibility garments are certified according to EN ISO 20471 and make the user visible to the environment in daylight, darkness and in bad weather.
High-visibility clothing has a fluorescent surface and reflectors that meet requirements according to three different classes depending on how visible they are. Class 3 is the highest safety class. The certified class can be achieved with a single garment or a garment combination*. A class 3 garment shall cover the torso and shall have either sleeve with reflectors or full-length trouser legs with reflectors.
*in Europe it is acceptable to combine EN ISO 20471 Class 1 Trousers with EN ISO 20471 Class 2 jacket/Top to create an ensemble that equals EN ISO 20471 Class 3, HOWEVER this method is not acceptable for UK highways – the torso protection MUST confirm to EN ISO 20471 Class 3 as a standalone garment.
