16、rds 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 organ
17、izations, 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 i
18、n 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 %
19、 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, Equipm

ISO 16003:2008(E) vi ISO 2008 All rights reservedIntroduction This International Standard has been prepared by a specialist working group of ISO/TC 21/SC 8 as a companion document to ISO 1
21、4520 (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 connec
22、tors, check valves and non-return valves, selector valves and associated actuators and discharge nozzles. CO 2system 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
23、 12094 (all parts). INTERNATIONAL STANDARD ISO 16003:2008(E) ISO 2008 All rights reserved 1 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; a
24、nd 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; sele
25、ctor 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 contr
26、ol 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 Stan
27、dard 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
28、 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. 2 Normative references The following referenced documents are indispensable for the application of this docume
