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).

Introduction
Extended coverage sprinklers are intended provide fire control in occupancies or portions of
occupancies where the quantity and/or combustibility of contents is low and fires with relatively low
rates of heat release are expected. Examples of occupancies where these sprinklers may be installed
include offices, restaurant seating areas, educational facilities and other areas having similar fire
challenges.
These sprinklers have a relatively flat spray pattern compared to the sprinklers described in ISO 6182-1.
This allows the sprinklers to effectively distribute water over a larger area; thus permitting the
sprinklers to be spaced greater distances from each other, as well as from the walls of the compartment.
Obstructions can pose a greater challenge to extended coverage sprinklers because of the flat spray
pattern. Extended coverage sprinkler installation guidelines need to account for the flat spray pattern
when considering the distances between obstructions and the sprinkler.
Product standards, such as this one, can provide a minimum level of safety in the built environment, as
well as a level of quality to the products on the market.
