TS ISO 23155

TS ISO 23155 is the standard that addresses requirements and recommendations for how conference interpreting services are provided. The technical focus is the professional organisation of spoken-language mediation in conference settings, where consistency, role clarity and service coordination are essential to effective multilingual communication.

What the standard covers

This standard is concerned with the provision of conference interpreting services, meaning the service framework used when spoken messages at meetings, congresses, seminars or similar events are rendered into another language in real time. Its purpose is to help preserve the flow of communication while supporting accurate transfer of meaning, tone and communicative intent. It provides a common reference point for interpreting service providers, conference interpreters and users of those services.

General technical context for conference interpreting

Conference interpreting differs from written translation because it depends heavily on speaking rate, turn-taking, terminology consistency and event logistics. In practice, service quality is shaped by factors such as simultaneous or consecutive interpreting modes, team coordination and preparation. A standard in this area is valuable because it helps clarify responsibilities, support service planning and establish shared expectations among the parties involved.
