What Does ISO 23155 Guarantee in Conference Interpreting and How Does It Benefit Your Event?

In international events, multilateral congresses, and institutional meetings, simultaneous interpreting cannot be left to chance. The quality of the service directly impacts message comprehension, the organizer’s reputation, and the overall success of the event.

ISO 23155 sets international requirements for delivering high-quality simultaneous interpreting services. But beyond the technical aspects, what does it really mean for you as a client?

What is ISO 23155?

ISO 23155 is an international standard that defines the requirements for organizing and providing simultaneous interpreting services. It establishes clear criteria regarding:

• Interpreter preparation in advance

• Adequate technical conditions

• Booth and sound equipment

• Professional coordination

• Responsibilities of the service provider

Its goal is to ensure that interpreting is carried out under optimal conditions to preserve the fidelity of the original message.

Direct Benefits for Your Event

1. Accuracy and faithfulness to the message

The standard requires rigorous terminological preparation and prior access to relevant documentation. This reduces the risk of errors, ambiguities, or inaccurate interpretations, especially in technical, legal, institutional, or corporate contexts.

For the client, this means communicative confidence.

2. Reduction of technical risks

ISO 23155 specifies minimum requirements for audio quality, appropriate booths, and technical coordination. Poor sound quality directly affects the interpreter’s performance and, consequently, the final outcome.

Compliance with the standard minimizes interruptions, failures, and the loss of critical information.

3.Structured Professionalism

It is not just about speaking two languages. The standard reinforces clear professional processes: planning, coordination, confidentiality, and ethical standards.

For the organizer, this translates into peace of mind and predictability.

4. Protection of Event Reputation

In international meetings, poor interpreting can negatively impact the image of the organizing institution or company. Applying international standards reduces this risk and conveys professionalism.

5. Adaptation to On-site, Remote, and Hybrid Formats

The standard also addresses remote environments. In a context where hybrid events are common, ensuring proper technical standards is key to maintaining quality across all channels.

Why is it important to work with interpreters aligned with international atandards?

When an interpreter works according to standards like ISO 23155 and international professional principles, the client is not just hiring a language service but a structured workflow.

This includes:

• Advanced preparation

• Technical coordination

• Evaluation of working conditions

• Compliance with ethical criteria

• Professional responsibility

Conclusion

ISO 23155 is not an irrelevant technical detail. It is a structural quality guarantee that protects your event, your message, and your reputation.

When interpreting is managed under international standards, communication flows with precision, rigor, and confidence.

In events where every word counts, standards matter.
