TS 7747

TS 7747 is a vocabulary standard for electrotechnical terms and definitions used for electromechanical components in electronic equipment. Standards of this kind reduce ambiguity in naming and help create a common language for engineering documents, catalogues, technical drawings, and maintenance texts.

Groups of terms covered by the vocabulary

The scope covers general components, the parts of those components, the properties of those parts, and the related technical characteristics. It also includes terms for replacement characteristics of a component, surrounding elements, and connecting components, together with the parts and properties of those connecting elements. The focus is not on how a product is designed, but on establishing consistent terminology for electromechanical components.

Technical context of electromechanical components

Electromechanical components combine electrical function with mechanical motion or interaction. They are commonly involved in switching, contact making, latching, movement transmission, or connection functions. In electronic equipment, precise terminology matters because terms such as housing, contact, actuator, terminal, or connector element can describe different physical features and functional roles. The standard’s value lies in clarifying these distinctions in technical communication.

This TS 7747 edition was published as equivalent to IEC 50/581:1978 and is now withdrawn. It is therefore a historical terminology reference rather than a document specifying test methods or performance requirements.
