The work of preparing International Standards is normally carried out through ISO technical com
10、mittees. 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
11、 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 Internatio
12、nal 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 t
13、he 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 cance
14、ls 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
15、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: Requir

18、his part of ISO 6182 specifies performance requirements, methods of test and marking requirements for deluge valves and manufacturers specified relevant trim used in deluge and pre-action automatic fire protection systems. Deluge valves covered by these requirements can be operated by hydraulic, pne
19、umatic, 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
20、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. 2 Normative references The following referenced documents are indispens
