This class designation (the X next to the symbol) indicates the class in relation to how well the product is able to offer protection. The highest class that can be achieved is class 3. In EN ISO 20471, all reflectors must meet the requirements for class 2 with regard to the reflector’s ability to reflect light. If the manufacturer so desires, combined outfits can be classified according to a higher protection class than the one given to a single garment used on its own. The possible higher class is specified on the label of the garment. Clothing that is certified in accordance with this version is tested after washing. Unless otherwise stated on the clothing label, the material has been tested after five wash cycles.
