EN ISO 20471 Class 3

High visibility garments must all conform to EN ISO 20471 safety standards and then are classified by the volume of fluorescent and retroflective surface areas. Class 3 is the highest level of hi-vis classification and these products require a minimum 0.8m² of fluorescent material and 0.2m² of reflective tape. It is possible to combine Class 1 and Class 2 products to also meet the Class 3 standard.
