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.
ISO 30061 was prepared as Standard CIE S 020/E by the International Commission on Illumination, which
has been recognized by the ISO Council as an international standardizing body. It was adopted by ISO under
a special procedure which requires approval by at least 75 % of the member bodies casting a vote, and is
published as a joint ISO/CIE edition.
The International Commission on Illumination (abbreviated as CIE from its French title) is an organization
devoted to international cooperation and exchange of information among its member countries on all matters
relating to the science and art of lighting.
ISO 30061 was prepared by CIE Technical Committee 5-19 Emergency Lighting.

FOREWORD
Standards produced by the Commission Internationale de l’Eclairage (CIE) are a concise
documentation of data defining aspects of light and lighting, for which international harmony
requires such unique definition. CIE Standards are therefore a primary source of
internationally accepted and agreed data, which can be taken, essentially unaltered, into
universal standard systems.
This CIE Standard has been prepared by CIE Technical Committee TC 5-19*

EMERGENCY LIGHTING
1. INTRODUCTION
The primary objective of emergency lighting is the provision of visual conditions that can
alleviate panic and facilitate safer evacuation of buildings’ occupants during the failure of
normal power supply/lighting, in clear (non-smoke) and smoke filled conditions.
The emergency lighting scheme design should be based on worst conditions (e.g.
minimum light output, maximum glare limits) of the luminaires during operating life and should
be based only on direct light from luminaires. The contributions by room surface inter-
reflections should be ignored. However, in lighting systems such as indirect luminaires or
uplights (used in maintained/combined mode), where the luminaire works in conjunction with
a reflecting surface, the first reflection should be taken as direct light from the system and
subsequent reflections should be ignored.
The requirements given in this standard are a minimum for design purposes and are
calculated for the full rated duration period and end of design life of the equipment. A special
chapter for smoke is included.
Safety signs may also fulfil further functions within maintained operation.
In most countries, states or towns statutory regulations relating to emergency lighting
already exist. For this reason, the appropriate authority should always be consulted before
commencing the design of a specific emergency lighting system. It is hoped that by providing
an international standard, lighting technical requirements in local statutory regulations will
converge on that standard.
2. SCOPE
This standard specifies the luminous requirements for emergency lighting systems installed in
premises or locations where such systems are required. It is principally applicable to locations
where the public or workers have access.
