Short definition
DIN EN ISO 20109 is the international standard for simultaneous interpreting equipment – it sets minimum technical requirements for interpreting systems and their components.
Detailed explanation
Standards aren't dry bureaucracy – they're the backbone of professional quality assurance. DIN EN ISO 20109 defines the technical requirements interpreting systems must meet: audio quality, number of channels, control desk functions, transmission paths, and requirements for interpreter consoles in the booths.
The standard applies to all types of transmission systems – infrared, radio, wired systems – and makes quality requirements measurable. It's closely linked to ISO 2603 (fixed interpreting booths) and ISO 4043 (mobile booths), which define requirements for the physical structure.
For technical providers who rent out or operate professional interpreting systems, knowing this standard is essential. It protects interpreters, ensures the quality of interpretation, and is often cited as a minimum requirement in public tenders.
Relevance in this subject area
DIN EN ISO 20109 is the technical quality benchmark for simultaneous interpreting systems. Anyone working professionally knows it – and complies with it.
Practical example
A public contracting authority puts out a tender for equipping a multilingual conference and explicitly requires systems compliant with DIN EN ISO 20109 in the tender documents. Providers must demonstrate the compliance of their systems.
