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 6182-3 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 6182-3:2005), 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

Introduction
This part of ISO 6182 is one of a number of International Standards prepared by ISO/TC 21 covering
components for automatic sprinkler systems, including the following:
a) Carbon dioxide systems (ISO 6183);
b) Explosion suppression systems (ISO 6184).
An International Standard covering foam systems is planned.

Part 3:
Requirements and test methods for dry pipe valves
1 Scope
This part of ISO 6182 specifies performance, requirements, methods of test and marking requirements,
for dry pipe valves and manufacturer’s specified relevant trim used in dry pipe automatic fire
protection systems.
Performance and test requirements for other auxiliary components or attachments to dry pipe valves
are not covered by this part of ISO 6182. Quick opening devices, including accelerators, used with dry
pipe valves are covered in 6182-4.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 898-1, Mechanical properties of fasteners made of carbon steel and alloy steel — Part 1: Bolts, screws
and studs with specified property classes — Coarse thread and fine pitch thread
ISO 898-2, Mechanical properties of fasteners made of carbon steel and alloy steel — Part 2: Nuts with
specified property classes — Coarse thread and fine pitch thread
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
alarm device
mechanical or electrical device to sound an alarm upon operation of the valve
3.2
automatic drain
normally open device that automatically drains water from and vents the intermediate chamber of a
valve to the atmosphere when the valve is in the ready position, and limits water flow from the chamber
after the valve has tripped
3.3
clapper
type of sealing element
NOTE See also 3.18.
3.4
corrosion-resistant material
1)
metallic material of bronze, brass, Monel metal, austenitic stainless steel, or equivalent, or plastic
material conforming with the requirements of this part of ISO 6182

1) Monel is an example of a suitable product available commercially. This information is given for the convenience
of users of this part of ISO 6182 and does not constitute an endorsement by ISO of this product.
