Protection for all types of weather. EN ISO 20471:2013 All our high visibility conforms to the European norm EN ISO 20471: 2013. The garments that conform to this norm are given a specific class depending on the size of the area of the respective material (fluorescent and reflective). Class 3 has the highest visibility. For each class, the norm dictates the area and placement of the fluorescent, reflective and contrast materials. To reach a higher visibility and class, garments with lower class can be combined. To be sure you reach class 3 keep in mind that 2+2 always adds up to 3 when talking about high visibility clothing. How high-vis garments work in the dark The reflective material in the garment works in the same way as a road sign. When headlights shine on the clothing, the material reflects the light back in the direction of the light source. In the light of a car’s headlights, regular clothing is visible at a distance of 150 metres, while reflective workwear is visible at a distance of 450 metres! Bear in mind that the beam of light from a car shines on the lower part of the body first. For this reason, reflectors on the legs are most visible. 1237 AllroundWork, Women’s High-Vis Softshell Jacket Class 2/3 ORANGE TRUMPS YELLOW DURING WINTER It’s usually easier to spot a person wearing yellow fluorescent garments compared to orange. This is because yellow has higher luminous power than orange, meaning it appears brighter to the eye from a specific angle. In a white winter landscape, however, the opposite applies. This is because orange provides a higher contrast to a white background. So, although orange has lower luminance than a yellow fluorescent material, the orange colour is more visible in a winter landscape because of higher contrast. In this case, contrast trumps luminance. How high-vis garments work in daylight The fluorescent material converts invisible ultraviolet light into visible light, which gives the garment a brightness that makes it stand out. 50 100 150 200 250 300 350 400 The illustration shows how the visibility differs between persons wearing dark, light and reflective clothing while illuminated by high and low beam lights. Dark person – dark clothes. White person – light-coloured clothes. Yellow person – reflective workwear. 450 m Snickers Workwear I autumn/winter 2018 57
