The EN13356:2001 directive standard specifies the optical performance requirements and surface area requirements for accessories intended for non-professional use, and intended to signal the user's presence visually when illuminated by vehicles on dark roads. The accessories can be worn, attached to or carried by persons. This standard does not apply to garments.
There are 2 ways to present the certificate:
The producer sends the products for testing to accredited laboratories and get documentary which corroborates that the product is tested officially.

If the compliance statement is untrue, the producer will face the consequences in court.

Type 1: Free hanging, such as reflective hangers or dangle tags.
Type 2: Removable, such as slap wraps and arm bands.
Type 3: Mounted, such as adhesive stickers.
