In order to create protective clothing that effectively signals the presence of the wearer, the EN ISO 20471 standard outlines specific requirements for fabric and materials. This type of high-visibility clothing is designed to ensure the wearer is visible in all lighting conditions, whether during daylight or when illuminated by lamps at night.
To meet these standards, clothing must be inspected for particular colour and retro-reflection features. Additionally, the amount and type of materials used in creating the protective clothing is also taken into consideration to guarantee it meets minimal area requirements.
