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.

ISO 13943:2017(E)
Introduction
Over the last two decades, there has been a significant growth in the field of fire safety. There has been
a considerable development of fire safety engineering design, especially as it relates to construction
projects, as well as the development of concepts related to performance-based design. With this
continuing evolution, there is an increasing need for agreement on a common language in the broad and
expanding area of fire safety, beyond what traditionally has been limited to the field of fire testing.
The first edition of this vocabulary, ISO 13943:2000, contained definitions of about 180 terms. However,
the areas of technology that are related to fire safety have continued to evolve rapidly and this edition
contains many new terms and their definitions, as well as revised definitions of some of the terms that
were in earlier editions.
This document defines general terms to establish a vocabulary applicable to fire safety, including fire
safety in buildings and civil engineering works and other elements within the built environment. It will
be updated as terms and definitions for further concepts in the field of fire safety are agreed upon and
developed.
It is important to note that, it is possible that, when used for regulation, some fire safety terms may have
a somewhat different interpretation than the one used in this document and, in that case, the definition
given in this document may not apply.
The terms in this document are
— fundamental concepts,
— more specific concepts, such as those used specifically in fire testing or in fire safety engineering
and may be used in ISO or IEC fire standards, and
— related concepts, as exemplified by terms used in building and civil engineering.
Annex A provides an index of deprecated terms.
The layout is designed according to ISO 10241-1, unless otherwise specified. The terms are presented in
English alphabetical order and are in bold type except for deprecated terms, which are in normal type.
Use of the term “item”
For the purposes of this document, in the English version, the term “item” (and in French “objet”) is
used in a general meaning to represent any single object or assembly of objects, and may cover, for
example, material, product, assembly, structure or building, as required in the context of any individual
definition.
If the “item” under consideration is a test specimen, then the term “test specimen” is used.
The German version uses terminology such as material, product, kit, assembly and/or building to clarify
the meaning of each definition.

acceptance criteria
criteria that form the basis for assessing the acceptability of the safety of a design of a built
environment (3.32)
Note 1 to entry: The criteria can be qualitative, quantitative or a combination of both.
3.4
accuracy
closeness of the agreement between the result of a measurement and the true value of the measurand
[SOURCE: ASTM E176: 2015]
3.5
activation time
time interval from response by a sensing device until the suppression system (3.375), smoke (3.347)
control system, alarm system or other fire safety system is fully operational
3.6
active fire protection
method(s) used to reduce or prevent the spread and effects of fire (3.114), heat or smoke (3.347) by
virtue of detection and/or suppression of the fire and which require a certain amount of motion and/or
response to be activated
EXAMPLE The application of agents (e.g. halon gas or water spray) to the fire or the control of ventilation
and/or smoke.
ISO 13943:2017(E)
Note 1 to entry: Compare with the terms passive fire protection (3.293) and suppression systems (3.375).
