A Technical Standard Order (TSO) part is one that has been manufactured to meet specific performance standards as dictated by the Federal Aviation Administration (FAA). With TSO standardization, authorities ensure that materials, parts, and appliances all have been approved for production and have shown how they will be installed and function on a particular aircraft.
