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

    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
