Authorization
Receiving a TSO authorization is approval to manufacture an article that may be installed on an aircraft only after showing that the article meets the specific airworthiness requirements (certification basis) of a particular aircraft model. In other words, receiving a TSO authorization means that an article meets a minimum performance requirement independent of the article's intended installation on an aircraft. A separate FAA approval is required to install the article on an aircraft.
Contact your local FAA office to request an application for TSO Authorization.
