Glass vs. Plastic

Reflectors and road marking studs are subject to the harshest influences. The requirements for these products are defined in the EN 1463 standards family. To cover the different material properties, the EN 1463 standard differentiates between three different types of reflectors:

Type 1: Glass
Type 2: Plastic
Type 3: Plastic with surface protection

All test samples are tested for resistance to the following influences:

  • Salt corrosion (salt spray test)

  • Sulphur dioxide (Kesternich test)
  • UV radiation (Arizona sun test)

  • Air humidity and temperature (climate test)

  • Abrasion (abrasion test)
