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 16003 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 8, Gaseous media and firefighting systems using gas.

Introduction
This International Standard has been prepared by a specialist working group of ISO/TC 21/SC 8 as a
companion document to ISO 14520 (all parts) and is compatible with corresponding documents prepared by
CEN. It does not cover all components incorporated in gaseous fire extinguishing systems dealt with in
ISO 14520 (all parts); rather, it is restricted to key components only, viz., container valve assemblies, flexible
connectors, check valves and non-return valves, selector valves and associated actuators and discharge
nozzles.
CO system components are also covered by this International Standard (see ISO 6183).
NOTE The components requirements of this International Standard are also satisfied by the requirements of
EN 12094 (all parts).

INTERNATIONAL STANDARD ISO 16003:2008(E)

Components for fire-extinguishing systems using gas —
Requirements and test methods — Container valve assemblies
and their actuators; selector valves and their actuators;
nozzles; flexible and rigid connectors; and check valves and
non-return valves
1 Scope
This International Standard specifies requirements and describes test methods for the following components
used in gaseous fire-extinguishing systems: container valve assemblies, which include container valve,
actuator and, if applicable, a diptube; selector valves and their actuators; agent distribution nozzles; flexible
connectors; and check and non-return valves.
Container valve assemblies are designed to control the extinguishant flow from the container to the
distribution pipe work. They are normally in the closed position. The automatic control device triggers the
actuator and the valve opens. Where applicable, the requirements contained in the test methods also apply to
separate container valves.
The design of the nozzles influences the area coverage, the height limitations, the discharge rate and the flow
rate.
This International Standard is applicable to check valves installed between container valve and manifold and
non-return valves installed in pilot lines, except those valves that are tested in combination with non-electrical
control devices. It is required that non-return and check valves allow the passage in the direction of flow and
prevent flow in the reverse direction.
NOTE For the purpose of this International Standard, the pressure in megapascals (bars) means gauge pressure,
unless otherwise indicated.

4.28 Documentation
4.28.1 The manufacturer shall prepare and maintain documentation that specifies the installation, operation,
routine testing and maintenance procedures applicable to the component and all other information relating to
its incorporation within a fire-extinguishing system.
4.28.2 The manufacturer shall prepare installation and user documentation, which shall be submitted to the
testing authority together with the sample(s). This documentation shall be comprised of at least the following:
a) general description of the component, including a list of its features and functions;
b) technical specification including
⎯ the information specified in 4.1,
⎯ sufficient information to permit an assessment of the compatibility with other components of the
system (if applicable, e.g. mechanical, electric or software compatibility);
c) installation instructions including
⎯ the suitability for use in different environments,
⎯ mounting instructions,
⎯ operating instructions,
⎯ maintenance instructions.
4.28.3 The manufacturer shall prepare design documentation, which shall be submitted to the testing
authority together with the sample(s). This documentation shall include drawings, parts lists, block diagrams
(if applicable), circuit diagrams (if applicable) and a functional description in sufficient detail that compliance
with this International Standard can be checked and that a general assessment of the design is possible.
4.28.4 An installation, operation and maintenance manual and a design manual (when applicable) shall
either be provided with each automatic extinguisher or extinguishing system unit or be made available upon
request. When these manuals are not included with each system, an owner's manual shall be shipped with
each system.
5 Test methods
5.1 Test conditions
The components shall be assembled for test as specified in the technical description. The tests shall be
carried out at a temperature of (25 ± 10) °C, except when otherwise specified for a particular test. The
tolerance for all test parameters is ± 5 %, unless otherwise specified.
5.2 Test samples and order of tests
The number of samples of each component type and the order of testing of each component are given in the
relevant table as follows:
⎯ container valves and their actuators: Table 5;
⎯ selector valves and their actuators: Table 6;
⎯ nozzles: Table 7;
⎯ flexible connectors: Table 8;
⎯ check valves and non-return valves: Table 9.
