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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire

fighting, Sub-committee SC 8, Gaseous media and firefighting systems using gas.

This second edition cancels and replaces the first edition (ISO/TR 23107:2019), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— the title has been modified;
— additional information has been added to the Introduction;
— the Scope has been reworded;

— checklist items 7.5, 7.5.1 and 7.5.2 have been renumbered 8, 8.1 and 8.2 respectively.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction

The ISO 14520 series sets forth important information necessary for introducing total flooding fire

extinguishing agents into the marketplace. Important information includes that related to physical,

thermodynamic and chemical properties, safe exposure criteria, performance criteria such as minimum

extinguishing and design concentrations, and environment characteristics.

This document includes technical information related to the design and use of total flooding fire

extinguishing systems using liquefied or non-liquefied gaseous fire extinguishing agents. Suggested

minimum extinguishant information includes:
