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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
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.
ISO 6182-5 was prepared by Technical Committee 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 6182-5:2006), which has been
technically revised.
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
— Part 5: Requirements and test methods for deluge valves
— Part 6: Requirements and test methods for check valves
— Part 7: Requirements and test methods for early suppression fast response (ESFR) sprinklers
— Part 8: Requirements and test methods for pre-action dry alarm valves
— Part 9: Requirements and test methods for water mist nozzles
— Part 10: Requirements and test methods for domestic sprinklers
— Part 11: Requirements and test methods for pipe hangers
— Part 12: Requirements and test methods for grooved-end components for steel pipe systems

INTERNATIONAL STANDARD ISO 6182-5:2012(E)
Fire protection — Automatic sprinkler systems —
Part 5:
Requirements and test methods for deluge valves
1 Scope
This part of ISO 6182 specifies performance requirements, methods of test and marking requirements
for deluge valves and manufacturer’s specified relevant trim used in deluge and pre-action automatic
fire protection systems. Deluge valves covered by these requirements can be operated by hydraulic,
pneumatic, electric, mechanical, manual, or thermal means, or combinations thereof.
Performance and test requirements for other auxiliary components or attachments to deluge valves are
not covered by this part of ISO 6182.
This part of ISO 6182 does not cover thermally operated valves released by heat acting directly on the
valve. This type of valve utilizes a thermal device, such as the link-and-lever arrangement or glass bulb
of a sprinkler, to hold the valve closed. Operation of the thermal device allows the valve to open.

less than 800 °C shall not form part of the valve body or cover.
4.4.4 It shall not be possible to assemble the valve with the cover plate in a position which either
