Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

Subcommittee SC 5, Translation, interpreting and related technology, in collaboration with the European

services, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna

Agreement).

This first edition cancels and replaces ISO/PAS 24019:2020, which has been technically revised.

The main changes are as follows:

— the document has been restructured to attribute requirements and recommendations to the

different parties in the audio and video path;

— a simultaneous interpreting delivery platform can be used in conjunction with another system;

— a new clause has been added, entitled “Overall performance”;
— the clause on continuity of transmission has been altered;

— a new clause has been added, entitled “Information on the quality of the speaker or signer’s input”;

— requirements for signed language interpreting have been added;
— communication between interpreters with sound and image has been added;

— requirements about the working environment of both speakers and signers have been added;

— the original annex on information security has been incorporated into the body of the document;

— an annex on audible and visual disturbance has been added;
— an annex including recommendations for microphones has been added;
— an annex including recommendations for test protocols has been added.

Introduction

Using simultaneous interpreting delivery platforms is relatively new to conference organizers,

participants and interpreters alike. Parameters and conditions for using these platforms in settings

where the interpreters are not at the same venue as participants, speakers and signers or each other

are evolving.

In January 2020, ISO/PAS 24019 was published to provide guidance to those developing simultaneous

interpreting delivery platforms. At the same time, it was decided that an International Standard was

needed to go into more depth regarding the requirements and recommendations for such platforms.

This document covers simultaneous interpreting delivery platforms for spoken and signed language

interpreting.

Equipment and facilities for simultaneous interpreting are covered in ISO 2603, ISO 4043, ISO 20108

and ISO 20109. Conference systems, and their related interpreting systems, are covered in ISO 22259.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction

Using simultaneous interpreting delivery platforms is relatively new to interpreters. Parameters and

conditions for using these services in settings where the interpreters are not at the same venue as

participants, speakers and signers are evolving. Developers, providers, users and interpreters need

information about requirements and recommendations relating to these platforms.

Early 2020 a Publicly Available Specification (ISO/PAS 24019, Simultaneous interpreting delivery

platforms — Requirements and recommendations) was published to structure the very recent

development of these platforms. At the same time, it was decided that a full-fledged standard was

needed to go into more depth and detail regarding the requirements and recommendations for such

platforms.

The pandemic public health situation affecting the entire world completely changed the meeting and

conference market. It led to an unprecedented surge in the demand for distance meeting and interpreting

facilities, in which simultaneous interpreting delivery platforms, amongst other technologies, play an

important part.

This document contains requirements and recommendations for the use of simultaneous interpreting

delivery platforms for spoken and signed language interpreting.

Equipment and facilities for simultaneous interpreting are also covered in ISO 2603, ISO 4043,

ISO 20108 and ISO 20109. Conference systems, and their related interpreting systems, are covered in

ISO 22259.

Simultaneous interpreting delivery platforms —
Requirements and recommendations
1 Scope

This document specifies requirements and recommendations for using simultaneous interpreting

delivery platforms at communicative events where the interpreters are not at the same venue as

participants, speakers and signers.

In cases where interpreters are at the same venue as participants, speakers and signers, ISO 20109

shall apply to ensure a high level working environment and the acoustic performance of the overall

conference system.

In conjunction with ISO 20108, this document provides requirements and recommendations for

ensuring the quality of sound and images and their transmission to interpreters and from interpreters

to participants, and for the configuration of the interpreter’s working environment.
