High visibility clothing EN ISO 20471
EN ISO 20471 specifies requirements for clothing that visually signals the user's presence – high visibility clothing. The standard includes performance requirements for colour and retroreflection, as well as minimum areas and placement of fluorescent and reflective materials.
The high visibility clothing standard defines three different classes. Class 3 provides the highest visibility. Each class has specific requirements for the size of fluorescent, reflective, and contrasting areas, as well as their placement. Since they serve different purposes, fluorescent and reflective materials cannot replace each other in terms of surface area calculation.
Protective clothing against rain EN 343
Standard EN 343 specifies the performance and requirements for clothing that protects against rain and vapor. The purpose is to protect you from getting wet and cold from rain, as it can hinder you in your work. The standard defines the resistance to water penetration that the fabric and seams of the garment should have, as well as its resistance to water vapor. Both of these properties are classified into three different levels: 1, 2, and 3. Class 3 has the highest performance and provides the best protection.
Due to heavy sweating and clothing with poor ventilation (breathability), you can still get wet and cold from the inside even with a certified product that protects against rain. To minimize the amount of water vapor (sweat) from the body, you should choose clothing based on the intensity of the work. The higher the intensity of the work, the better breathability you need, and vice versa.
