Fire protection -- Automatic sprinkler systems -- Part 1: Requirements and test methods for sprinklers

This part of ISO 6182 specifies performance and marking requirements and test methods for conventional,
spray, flat spray, and sidewall sprinklers. It is not applicable to sprinklers having multiple orifices.
NOTE The requirements for early suppression fast response (ESFR) sprinklers are in ISO 6182-7; the
requirements for domestic sprinklers are in ISO 6182-10; and the requirements for extended coverage (EC)
sprinklers are under development.

Požarna zaščita - Avtomatski sprinklerski sistemi - 1. del: Zahteve in preskusne metode za sprinklerje

Ta del standarda ISO 6182 določa zahteve za zmogljivost in označevanje ter preskusne metode za običajne, ploske in stenske sprinklerje. Ne uporablja se za sprinklerje z več odprtinami.
OPOMBA Zahteve za sprinklerje ESFR (early suppression fast response) so zajete v standardu ISO 6182-7; zahteve za sprinklerje za gospodinjstva so zajete v standardu ISO 6182-10; zahteve za sprinklerje EC (extended coverage) so v pripravi.

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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 5, Fixed firefighting systems using water.
This third edition cancels and replaces the second edition (ISO 6182-1:2004), of which it constitutes a
minor revision.
ISO 6182 consists of the following parts, under the general title Fire protection — Automatic sprinkler
systems:
— Part 1: Requirements and test methods for sprinklers
— Part 2: Requirements and test methods for wet alarm valves, retard chambers and water motor alarms
— Part 3: Requirements and test methods for dry pipe valves
— Part 4: Requirements and test methods for quick-opening devices
