TS 12404

TS 12404 is a professional standard for the radio and television repairer occupation. It addresses how practitioners in this trade are defined and classified, and it sets out the knowledge, skills, behaviour, and equipment framework expected for the job. In technical terms, the occupation centers on fault finding, repair, adjustment, and verification work on radio and audio-video equipment.

Occupational definition and classification

The main purpose of this standard is to clarify what counts as competent practice in radio and television repair. That kind of framework helps distinguish levels of responsibility within the same trade, from routine maintenance tasks to more complex electronic troubleshooting. The standard is aimed at describing the competency profile associated with the occupation rather than turning the subject into a generic repair label.

General technical context

From a general technical perspective, radio and television repair involves components and subsystems such as signal paths, power supplies, RF/IF stages, audio and video circuits, connectors, and user interface elements. Troubleshooting commonly relies on measurement, circuit inspection, component replacement, safe disassembly/reassembly, and functional testing. Framed as a vocational standard, the subject is not only about tools and test equipment, but also about work discipline, correct procedures, and professional conduct.
