Short definition
E DIN ISO 22259 is a standard for conference systems that defines technical requirements for conference equipment with integrated microphone and speech distribution functions.
Detailed explanation
Conference systems are complex – they combine microphone technology, signal distribution, speaker management, and often interpreting functions in a single integrated system. ISO 22259 brings clarity here: it defines what a conference system must technically deliver, what functional classes exist, and what minimum requirements apply to audio quality, operation, and system integration.
The standard distinguishes between different system classes – from simple discussion systems to fully integrated conference systems with simultaneous interpreting, voting functions, and digital signal processing. It's therefore broader in scope than ISO 20109, which focuses specifically on simultaneous interpreting systems.
For planners and buyers, the standard provides a reliable reference framework for comparing different offers and systems. Knowing which system class a product belongs to under ISO 22259 makes it possible to define requirements more precisely and evaluate proposals more effectively.
Relevance in this subject area
ISO 22259 is the overarching standard for conference systems – it complements the more specific standards for booths and simultaneous systems and creates a shared quality framework.
Practical example
A manufacturer of conference systems certifies its new system to ISO 22259. Sales teams can then provide documented proof of standard compliance to public contracting authorities and international clients.
