Discs belonging to the same group must have following features, as indicated at following paragraphs from 2.1 to 2.9.
Ruka stola poveže se s otvorom izbušenim na kočnom disku.
For a given group of discs, the approval tests may be performed on one disc, belonging to the group, subjected to the highest braking torque and to the largest energy to be absorbed.
