EN 20471 (CLASE 1)

EN ISO 20471 Class 1 is a European standard specifying the requirements for high-visibility warning clothing providing a basic level of visibility. Its purpose is to improve wearer safety by enhancing visibility during daylight and in low-light conditions. Garments certified according to EN ISO 20471 Class 1 contain the minimum required amount of fluorescent material and reflective elements, providing a basic level of protection in working environments with lower visibility risks. Class 1 garments are intended for workers operating in areas with limited vehicle traffic and relatively low visibility hazards. Compared to Class 2, Class 1 provides a lower level of visibility, while Class 3 offers the highest level of protection defined by the standard.
