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

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/

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;

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:
— identification;
— spe
