Guide To: ECE R150 - Retro-Reflective Devices (RRD)

UN ECE R150, or Regulation No. 150 of the Economic Commission for Europe of the United Nations, is a regulation that specifies the requirements for retro-reflective devices and markings for power-driven vehicles and their trailers.

Retro-reflective devices and markings are used to improve the visibility of vehicles, especially at night and in poor weather conditions. They reflect light back to the source, making them more visible to other road users.

UN ECE R150 applies to all retro-reflective devices and markings that are installed on vehicles. The regulation specifies the size, shape, color, and photometric performance of these devices and markings. It also specifies the test methods that must be used to verify that they meet the requirements of the regulation.

UN ECE R150 is recognized by many countries around the world. This means that retro-reflective devices and markings that have been approved under UN ECE R150 can be used on vehicles in these countries.

Here are some of the key requirements of UN ECE R150:

Retro-reflective devices and markings must be retro-reflective, meaning that they reflect light back to the source. Retro-reflective devices and markings must be of a type that is approved for use on vehicles. Retro-reflective devices and markings must be able to withstand a certain amount of vibration without deforming. UN ECE R150 is an important regulation that helps to improve the safety of vehicles on the road. By requiring retro-reflective devices and markings to meet certain standards, the regulation helps to ensure that these devices and markings are effective in improving the visibility of vehicles, especially at night and in poor weather conditions.

Here are some additional points about UN ECE R150:

Retro-reflective devices and markings must be marked with the UN ECE R150 approval number. Retro-reflective devices and markings must be installed in a way that ensures that they are visible to other road users. Retro-reflective devices and markings must be replaced if they are damaged or become defective. I hope this helps! Let me know if you have other questions.
