D3EA® testing allows aftermarket brake manufacturers to verify whether their products are consistent with the minimum United States Federal Motor Vehicle Safety Standards for brake performance requirements for new passenger vehicles.
D3EA® testing is conducted with vehicle specific hardware and test conditions. Each platform requires a unique set of test parameters and performance criteria. Development and validation of these specific tests and criteria is a major breakthrough in laboratory evaluation of brake friction materials.
- D3EA® testing does not address noise, wear or pulsation, but it does tell the customer which pads are suitable for the front brakes, and which pads or shoes are suitable for the rear brakes of a vehicle.
- The front and rear brake components are tested simultaneously to measure braking performance.
- The test simulates the vehicle weight and speed and measures the effectiveness of friction materials to determine their performance relative to that required by the vehicle.
- Because vehicles have different brake effectiveness requirements, D3EA® testing is available for different vehicle platform configurations.
- To identify replacement disc brake friction materials meeting the D3EA® criteria, a Certification Seal has been developed and is affixed to qualified parts.
- D3EA® Certification Seal appears only on replacement friction materials which meet platform-specific criteria. This
testing provides the installer
and the consumer with an objective basis for deciding which friction materials should be installed on a given vehicle.
Greening Testing Laboratories is the only lab to conduct Dual Dynamometer Differential Effectiveness Analysis). D3EA® certification meets the highest standard resulting in greater customer satisfaction and confidence. D3EA® takes the guess-work out of defining/determining the workload ratio between the front and rear braking systems. This ratio ultimately impacts stopping distance performance.
