New standard high visibility ISO20471 2013

Which evolutions compared to previous EN 471 ?

  • The width of reflective bands should be minimum 50mm, wherever it is situated
  • If clothes have sleeves, there should be both reflective and fluorescent elements on sleeves
  • Clothes must have sleeves to obtain class 3 certification, no vest can thus claim to be classify class 3.

The requirements in terms of conception and design are classified by type of garments, illustrated as examples below :
