What is EN ISO 20471:2016?

EN ISO 20471:2016 is an international standard that provides specifications for high-visibility clothing intended to enhance the visibility of wearers in hazardous situations, especially in low-light conditions. The standard specifies requirements for the design, material properties, and performance of such clothing items, with the aim to improve safety and reduce accidents in workplaces with risks associated with low visibility.

Design and Material Requirements of EN ISO 20471:2016

The standard lays down specific design features and material requirements that high-visibility clothing must adhere to. These include using fluorescent background material combined with retro-reflective tape or fabric to ensure maximum visibility at different light levels. The ratio of visible material to the background material is also specified to ensure optimum contrast. Clothing should be designed to provide 360-degree visibility when worn correctly and fulfill requirements for colour, luminance, and chromaticity.

Performance and Certification of High-Visibility Clothing

EN ISO 20471:2016 defines three different classes of high-visibility clothing based on the amount of visible fabric they possess and the level of risk present in the work environment. Class 1 provides the lowest level of visibility, suitable for low-risk situations. Class 2 and Class 3 offer higher levels of visibility, intended for higher-risk environments or where weather conditions may decrease visibility. Manufacturers are required to test their products according to specific methods and ensure compliance with the standard's requirements before affixing the CE mark.

Benefits and Importance of EN ISO 20471:2016

Adhering to EN ISO 20471:2016 benefits both employers and employees. By wearing high-visibility clothing that meets the standard's requirements, workers increase their visibility, reducing the risk of accidents and injuries caused by low visibility. Employers can demonstrate their commitment to employee safety and maintain compliance with health and safety regulations. Additionally, high-visibility clothing ensures that workers are easily identifiable, improving overall site security. By implementing the standard's guidelines, workplaces can create a safer environment that protects both workers and employers.
