About This Item
TS 9390 is a standard focused on the graphical symbols used on electrical equipment in medical practice. It brings together general symbols, symbols identifying the equipment class, safety symbols, and special symbols for ionizing-radiation equipment as well as for display, communication, and recording functions. In medical electrical equipment, symbols are especially important because they communicate essential information quickly and without relying on a specific language.
The role of symbols on medical electrical equipment
From a general technical perspective, these symbols help users recognize the equipment safely and distinguish its basic functions at a glance. Class-identifying symbols give clues about the electrical protection arrangement, while safety symbols point to hazards or precautions that deserve attention. Symbols related to display, communication, and recording are used to indicate functional areas such as screens, data transfer, or recording output.
Symbol groups covered by this standard
- General graphical symbols
- Symbols identifying the equipment class
- Safety symbols
- Special symbols for ionizing-radiation equipment
- Special symbols for display, communication, and recording
The document provides a consolidated list intended to support consistent recognition of these symbols in medical environments. TS 9390 was published as equivalent to IEC 878:1988 and is now withdrawn; even so, it remains useful as a historical reference for the terminology and marking conventions used on medical electrical equipment.
