1. Performance: Pads must be tested by an independent authorised body and must perform within ± 15% of the original friction material. The original brake pads are tested and the results are recorded for comparison. Then the aftermarket pad is tested in exactly the same way and the results are compared. Both sets of pads are initially  put through a bedding in cycle, weighed and measured for thickness. They are then put through a series of brake simulations using a Dynamometer or on vehicle tests.

These tests simulate braking at different speeds. Further tests are  then done to determine the performance, fade and recovery characteristics.

If the aftermarket pad performs to ± 15% of the original counterpart then a certificate of conformance and E number is issued 

2. Packaging: The outer packaging label must be marked with a defined set of information as shown.Including an illustration, application, contents and the approval number. The box must be tamper proof and contain a set of fitting instructions.
