EN ISO 20471: What are Hi-Vis Standards?
2 min read
What is EN ISO 20471?
The standard assesses the suitability and durability of retro-reflective materials. It doesn't support conventional workwear that may feature a small amount of Hi-Vis material used for decorative purposes. The requirements for the EN20471 maintains a 1-3 class system - class 3 provides the highest level that makes the wearer more visible.
20471 Hi Vis Vests
The majority of the vest range meet EN20471 Class 2, the intermediate level. If you require a Class 3 vest, look for a vest that has sleeves that features reflective material.
20471 Hi Vis Pants
The vast range of Hi-Vis trousers available today are Class 1, the minimum level of a fluorescent and retro reflective material. However, if you wear Class 1 trousers and combine them with a Class 2 jacket, you can bump up your protection to achieve Class 3.
20471 Hi Vis Fleece
Under the standards, if a sleeve on a sweatshirt or hoodie, blocks the view of the reflective bands on the torso then the sleeves must feature two reflective bands, positioned 50mm from each other.
20471 Hi Vis T shirts
To conform to the standards, the T-shirts and Hi-Vis polo shirts have been adapted - the sleeves have been shortened not to block a clear view of the horizontal torso bands. Where this has not been possible, a reflective band has been added.
