No. It is possible to create a group/family of products that can be issued under one certificate. Depending several criteria, we group parts together on factors like:
- Diameter for rotors and drums
- Thickness for rotors
- Material for lining, pads, drums and rotors
- Surface treatment for rotors
- Backing plate design for pads
- Friction design for pads
- Etc.
If a family or group is determined, the “Worst Case vehicle” is selected which is the application used to test the item that needs R90 certification.
