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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

Introduction
0.1 General
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 has traditionally been limited to the field of fire testing.
The first edition of this document, 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 in order 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 some fire safety terms can have a somewhat different interpretation than
the one used in this document when used for regulations. In that case, the definition given in this
document may not apply.
The terms in this document concern:
— fundamental concepts;
— more specific concepts, such as those used specifically in fire testing or in fire safety engineering
and potentially in ISO or IEC International Standards relating to fire; and
— related concepts, such as terms used in building and civil engineering.
The layout is designed according to ISO 10241-1:2011. The terms are presented in English alphabetical
order and preferred terms are written in bold type with admitted and deprecated terms listed below
in normal type.
0.2 Use of the term “item”
For the purposes of this document, the term “item” (in French “objet”) is used to represent any single
object or assembly of objects. It 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.
