Reasonable technical basis

Reasonable technical basis means information that would lead a person familiar with engine design and function to reasonably believe a conclusion related to compliance with the requirements of this part. For example, it would be reasonable to believe that parts performing the same function as the original parts (and to the same degree) would control emissions to the same degree as the original parts. Note that what is a reasonable basis for a person without technical training might not qualify as a reasonable technical basis.
